] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | This PR fixes a bug typo where in single-node settings, flos in the Trainer would stay constant, and also updates the flo count in the trainer state at every log occasion (instead of every model-saving occasion) so that users that wish to use a flo-logging callback can access it more frequently. I feel like the first bug should have been caught by a test (at the moment few other people use trainer flos, since it's mostly for large-scale training and researchers that need or want to report flos, and neither group uses the Trainer a lot, so it's mostly the HF bigscience efforts), and I should make one.

probably defined the `BertModel` inside it using `self.bert = BertModel.from_pretrained(\"...\")`. \r\n\r\nSo of course, you can't load it back into a `BertModel`, without first removing the \"bert\" prefix from all parameter names. Do you understand? You should however be able to directly load the weights into a `BertClassifier`.",
"Oh ok, so basically i have to remove the bert. prefix? And how would i have to do this ?",
"Is there a reason you don't want to load your weights into a `BertClassifier`, but only the `BertModel`? Because this:\r\n\r\n```\r\nmodel = BertClassifier(freeze_bert=False)\r\nmodel.load_state_dict(torch.load('finetuned_model.pt')))\r\n```\r\nshould work. In case you only want to have a `BertModel`, then you'll need to remove the \"bert\" prefix from the parameter names. This can be done as follows:\r\n\r\n```\r\nfrom transformers import BertModel, BertConfig\r\n\r\nmodel = BertClassifier(freeze_bert=False)\r\nmodel.load_state_dict(torch.load('finetuned_model.pt'))\r\n\r\nnew_state_dict = dict()\r\nfor name, param in model.state_dict().items():\r\n name = name[4:]\r\n new_state_dict[name] = param\r\n\r\nconfig = BertConfig.from_pretrained('bert-base-multilingual-uncased', num_labels=2)\r\nmodel = BertModel.from_pretrained('bert-base-multilingual-uncased')\r\n\r\nfor name, param in model.state_dict().items():\r\n model.state_dict()[name].copy_(new_state_dict[name])\r\n```\r\n\r\n\r\n",
"So the thing is, i trained and defined the BertClassifier in a .py file and in another .py file i want to use the fine-tuned model on user input data. If I do 'model = BertClassifier(freeze_bert=False)' i will have to import ` from bert import BertClassifier` and when i run the code, it starts the training of the model again... \r\n**Update:** So if i use the above code and after that torch.save the model.state_dict() and will it be the same finetuned model? will i have the same accuracy? ",
"If i just take the definition of BertClassifier class in the .py file where I want to test the model on user input and i do the following :\r\n```\r\nmodel = BertClassifier(freeze_bert=False)\r\nmodel.load_state_dict(torch.load('finetuned_model.pt'))\r\n```\r\nWill that be a workaround? As i told before, if I just import the BertClassifier from the other .py file where i trained it, on this file it will start the training again). Doing the above i see that doesn't start the training and `print(model.state_dict().keys())` returns `\"bert.embeddings.position_ids\", \"bert.embeddings.word_embeddings.weight\"` which should work fine if I'm not wrong. ",
"It's weird that when you import the model, it starts the training again. You only need to import the definition of the model, not the training related code.\r\n\r\n```\r\nmodel = BertClassifier(freeze_bert=False)\r\nmodel.load_state_dict(torch.load('finetuned_model.pt'))\r\n```\r\n\r\nThis should work indeed.

"Many thanks for the help!"
] | 1,621 | 1,621 | 1,621 | NONE | null | Hello, I’m having issues loading a finetuned BERT model for binary classification. I have this class for the BERT model:

super(BertClassifier, self).__init__()
self.bert = BertModel.from_pretrained('bert-base-multilingual-uncased')
self.lstm = nn.LSTM(768, 50, batch_first=True, bidirectional=True)

sequence_output = outputs[0]
sequence_output, _ = self.lstm(sequence_output)
linear_output = self.linear(sequence_output[:, -1])

```
The model is `bert_classifier = BertClassifier(freeze_bert=False)`
I save the model by the below line:
`torch.save(bert_classifier.state_dict(), 'finetuned_model.pt')`
Then in another .py file i want to load the model and i have the below code:
```

tokenizer = BertTokenizer.from_pretrained('bert-base-multilingual-uncased', do_lower_case=True)
model.load_state_dict(torch.load('finetuned_model.pt'))

I’ve tried to modify the save part to model.save_pretrained('finetuned_model.pt') but i received an error saying that save_pretrained function doesn’t exist in the model that i defined.
I also tried to save it with `torch.save(bert_classifier.state_dict(), 'finetuned_model.pt') `and load it with` model = BertModel.from_pretrained('finetuned_model.pt') `but i receive the error : `UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 64: invalid start byte`
And I also tried to save it like this `torch.save(bert_classifier.state_dict(), 'model/finetuned_model.bin')` and load it like this:
```
config = BertConfig.from_pretrained('bert-base-multilingual-uncased', num_labels=2)
model = BertModel.from_pretrained('bert-base-multilingual-uncased')
model.load_state_dict(torch.load("model/finetuned_model.bin"))
```
and received the same big error as above. Any idea how can this be fixed so i can save and load the model successfully ? Any help will be much appreciated. | {

when `data_args.line_by_line == False`, the script firstly converts given examples into input_ids, token_type_ids, attention_mask and special_tokens_mask including cls_token, sep_token. Then it concatenates all tokenized outputs and generate chunks of max_seq_length. However, it will generate unintended training examples such as [871, 512, 2492, 1111, 947, 533] not [2 (cls_token), 512, 2492, 1111, 947, 3 (sep_token)]. I fix this problem.
Fixes #11840

"Hey @abhikasd6523,\r\n\r\nI don't think that `generate()` currently supports `inputs_embeds` correctly. It would require quite some changes in `generate()` to make it work I'm afraid. Can you give me some more background on your use-case for passing `inputs_embeds` instead of `input_ids`. If it's a general enough use-case, I think we could try to make the required changes to `generate()`",

While solving this issue, I find that 'attention_mask' argument needs to be included too, to avoid this `self._prepare_attention_mask_for_generation` function being called altogether, another error pops ups.
The changes made are as follows:
```
from transformers import GPT2Tokenizer, GPT2LMHeadModel, GPT2Config

att_mask = torch.ones(tokenized_text.shape[1])
output = model.generate(inputs_embeds=tokenized_text_embeds, attention_mask=att_mask, max_length=50)
```

"Are you trying to convert it a HuggingFace TensorFlow object?

"Thank you for clarifying! In this case, if you have a PyTorch model that correctly loads (we recommend always using `from_pretrained`/`save_pretrained` rather than `.save()` and `torch.load`) that you want to convert to the \"original\" TensorFlow, then you should be able to use this script: \r\n\r\nhttps://github.com/huggingface/transformers/blob/master/src/transformers/models/bert/convert_bert_pytorch_checkpoint_to_original_tf.py\r\n\r\nIt will convert your model to a TF1 model usable in Google's original repository.",
"@LysandreJik thanks a lot. This solved my issue. Can you give me an idea about one thing: when I saved the tensorflow checkpoint with TFBertModel.from_pretrained(\"./demo_model\", from_pt=True).save(..) the saved checkpoint was smaller in size like 411 mb. Today I got the right sized checkpoint with the script you suggested (711 mb)....why the size was smaller in previous approach?",
"I'm not entirely sure, but I guess it would make sense for the sizes to be different as the saving format is different between TFBertModel (TF2) and the TF1 saved checkpoint. Maybe our TF expert @Rocketknight1 has more insights :)",
"No idea, unfortunately! I don't **think** the format changed that massively between TF1 and TF2.\r\n\r\nOne things that strikes me is that 711mb for a bert-base model is quite large: With 110M parameters, we should expect it to take up about 110*4 = 440mb of space uncompressed, because each parameter is a 32-bit (4-byte) float. That said, if it works, don't question it™",
"THANKS @LysandreJik AND @Rocketknight1 . This is helpful. Yes it took 440 earlier but when I used the tf1 conversion script it took 711 mb. I will finetune tydiqa on both of these models and let's see, if there is any difference any performence. "

The model is trained with DDP.
The error denotes that the batch is smaller than the model required.
However, the test file cannot use `droplast`.
How I can predict the test file with DDP or remove DDP?
### Code
```

warmup_ratio=0.1, # number of warmup steps for learning rate scheduler
weight_decay=1e-2, # strength of weight decay
logging_dir='./logs', # directory for storing logs
logging_steps=100,
evaluation_strategy='epoch',
gradient_accumulation_steps=4,

fp16=True
)
trainer = Trainer(

## Information
I tried to finetune mBART, T5, and MarianMTModel but all of them are running slowly on Colab TPUv2. I think the cause may come from Seq2seqTrainer since it works very well when I finetuned BERT on TPUv2 for MNLI Text classification.
The problem arises when using:
* The official example scripts: I use exactly the example parameter in README to train Translation model.
```
python xla_spawn.py --num_cores 8 \
seq2seq/run_translation.py \
--model_name_or_path Helsinki-NLP/opus-mt-en-ro \
--do_train \
--do_eval \
--source_lang en \
--target_lang ro \
--dataset_name wmt16 \
--dataset_config_name ro-en \
--output_dir /tmp/tst-translation \
--per_device_train_batch_size=4 \
--per_device_eval_batch_size=4 \
--overwrite_output_dir
```
I provide my [Colab notebook](https://colab.research.google.com/drive/1Y8kSbuZJ8ChIjgAf67F1cSciVaHfGTyq?usp=sharing)
The tasks I am working on is:
* an official GLUE/SQUaD task: WMT16

## Expected behavior
Currently, with each step, the training duration increases many times. I want the duration is more stable and faster than GPU.

"Hmmm - thinking about it - the value is also set to None by default in the constructor. I will close this..."
] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | Hi,
there are some places that implement `__getstate__` because an object has a reference to an other object that is not pickable.
`__getstate__` then "deletes" the reference by setting it to `None`. Just a few examples:
https://github.com/huggingface/transformers/blob/73fde1defe9be259a47b9024525882f3ec420994/src/transformers/models/m2m_100/tokenization_m2m_100.py#L272
https://github.com/huggingface/transformers/blob/73fde1defe9be259a47b9024525882f3ec420994/src/transformers/models/marian/tokenization_marian.py#L299
IMO it would be better to delete the keys instead of setting them to `None`. Like this: `del state["sp_model"]`
What do you think @sgugger @LysandreJik ? I can provide a PR if wanted. | {

## Information
Model I am using (Bert, XLNet ...): Wav2Vec2
The problem arises when using:
* [ X ] the official example scripts: (give details below)
* [ ] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
* [ X ] Automatic Speech Recognition
## To reproduce
Steps to reproduce the behavior:
1. Instantiate AutomaticSpeechRecognitionPipeline with device set to GPU
2. Run pipeline inference on example audio input
```
import transformers
model = transformers.Wav2Vec2ForCTC.from_pretrained("facebook/wav2vec2-large-xlsr-53-spanish")
tokenizer = transformers.AutoTokenizer.from_pretrained("facebook/wav2vec2-large-xlsr-53-spanish")
feature_extractor = transformers.AutoFeatureExtractor.from_pretrained("facebook/wav2vec2-large-xlsr-53-spanish")
pl = transformers.AutomaticSpeechRecognitionPipeline(feature_extractor=feature_extractor, model=model, tokenizer=tokenizer, framework='pt',device=0)
pl('waveform.wav')
```
The snippet above results in the following error:
`RuntimeError: Input type (torch.FloatTensor) and weight type (torch.cuda.FloatTensor) should be the same`
## Expected behavior
Inputs should be converted to CUDA tensor.
I believe this is happening because the feature extractor doesn't preserve the device.
I'm able to solve the issue if I add
`processed = self.ensure_tensor_on_device(**processed)`
after https://github.com/huggingface/transformers/blob/master/src/transformers/pipelines/automatic_speech_recognition.py#L136-L138
If this solution is acceptable, I'm happy to open a PR. | {

## Information
I am building a model (using Bert) which needs the `offsets` between tokens and original words. However, if I set `return_offset_mapping=True` in `BertTokenizerFast`, the returned encodings are not accepted by the model. Is this a bug or is it intended behavior?
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [x] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [x] my own task or dataset: (give details below)
## To reproduce
The following code snippet reproduces the problem for me:
```python
from transformers import BertTokenizerFast, BertModel
if __name__ == '__main__':
test_string = 'text with percentage%'
tokenizer = BertTokenizerFast.from_pretrained('bert-base-uncased')
encodings = tokenizer(test_string, return_offsets_mapping=True, return_tensors='pt')
print(encodings.keys())
model = BertModel.from_pretrained('bert-base-uncased')
out = model(**encodings)
```
I got the following error trace showing that `BertModel.forward()` does not accept `offset_mapping` which is included in the dict of `encodings`:
```
dict_keys(['input_ids', 'token_type_ids', 'attention_mask', 'offset_mapping'])
Traceback (most recent call last):
File "~/trans_test.py", line 9, in <module>
out = model(**tokens)
File "~/miniconda3/envs/tf/lib/python3.9/site-packages/torch/nn/modules/module.py", line 889, in _call_impl
result = self.forward(*input, **kwargs)
TypeError: forward() got an unexpected keyword argument 'offset_mapping'
```
<!-- If you have code snippets, error messages, stack traces please provide them here as well.
Important! Use code tags to correctly format your code. See https://help.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks#syntax-highlighting
Do not use screenshots, as they are hard to read and (more importantly) don't allow others to copy-and-paste your code.-->
## Expected behavior
At least, `Model.forward()` is supposed to have a key-arg placeholder for `offset_mapping`. For now, a workaround solution is to pop out `offset_mapping` from `encodings` before feeding the model. :(

Models:
- bert: @LysandreJik
Examples:
- maintained examples (not research project or legacy): @sgugger, @patil-suraj
## Information
Model I am using (Bert, XLNet ...): bert-base-cased
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [x] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [x] my own task or dataset: (give details below)
## To reproduce
Here are some modified parts from the official `run_glue.py` example.
The version of the `run_glue.py` was for v4.1.1.
https://github.com/huggingface/transformers/blob/v4.1.1/examples/text-classification/run_glue.py
``` python
# Preprocessing the datasets
if data_args.task_name is not None:
sentence1_key, sentence2_key = task_to_keys[data_args.task_name]
else:
# Again, we try to have some nice defaults but don't hesitate to tweak to your use case.
non_label_column_names = [name for name in datasets["train"].column_names if name != "label"]
if "sentence1" in non_label_column_names and "sentence2" in non_label_column_names:
sentence1_key, sentence2_key = "sentence1", "sentence2"
else:
if len(non_label_column_names) >= 2:
sentence1_key, sentence2_key = non_label_column_names[:2]
if sentence2_key == "id" or sentence2_key == "idx":
sentence2_key = None
else:
sentence1_key, sentence2_key = non_label_column_names[0], None
print(f"sentence1_key {sentence1_key}")
print(f"sentence2_key {sentence2_key}")
```
``` python
train_dataset = datasets["train"]
eval_dataset = datasets["validation_matched" if data_args.task_name == "mnli" else "validation"]
# if data_args.task_name is not None:
# test_dataset = datasets["test_matched" if data_args.task_name == "mnli" else "test"]
test_dataset = datasets["test_matched" if data_args.task_name == "mnli" else "test"]
# Log a few random samples from the training set:
for index in random.sample(range(len(train_dataset)), 3):
logger.info(f"Sample {index} of the training set: {train_dataset[index]}.")
# Get the metric function
if data_args.task_name is not None:
metric = load_metric("glue", data_args.task_name)
# TODO: When datasets metrics include regular accuracy, make an else here and remove special branch from
# compute_metrics
```
``` python
def compute_metrics(p: EvalPrediction):
preds = p.predictions[0] if isinstance(p.predictions, tuple) else p.predictions
preds = np.squeeze(preds) if is_regression else np.argmax(preds, axis=1)
if data_args.task_name is not None:
result = metric.compute(predictions=preds, references=p.label_ids)
if len(result) > 1:
result["combined_score"] = np.mean(list(result.values())).item()
return result
elif is_regression:
# return {"mse": ((preds - p.label_ids) ** 2).mean().item()}
# use the same metric as stsb (for pearsonr, spearmanr)
metric = load_metric("glue", "stsb")
result = metric.compute(predictions=preds, references=p.label_ids)
return result
else:
return {"accuracy": (preds == p.label_ids).astype(np.float32).mean().item()}
```
I tried to update my modified script referring to the latest version of `run_glue.py,` but it didn't solve the problem.
Steps to reproduce the behavior:
``` sh
(transformers4.1.1) $ CUDA_VISIBLE_DEVICES=0 python run_emobank_4.1.1.py \
--model_name_or_path bert-base-cased \
--train_file /path/to/train.csv \
--validation_file /path/to/validation.csv \
--test_file /path/to/test.csv \
--do_train \
--do_eval \
--do_predict \
--max_seq_length 64 \
--per_device_train_batch_size 32 \
--per_device_eval_batch_size 32 \
--learning_rate 2e-5 \
--num_train_epochs 10.0 \
--load_best_model_at_end \
--evaluation_strategy epoch \
--metric_for_best_model eval_pearson \
--output_dir /path/to/result/v4.1.1 \
--overwrite_output_dir
```
If I run the script with transformers 4.1.1, it works well.
If 4.6.0, it runs without any error, but the result is not good.
`4.1.1 validation result`
```
eval_loss = 0.10065479576587677
eval_pearson = 0.6559863196369287
eval_spearmanr = 0.6244913632922552
epoch = 10.0
```
`4.6.0 validation result`
```
eval_loss = 0.16216666996479034
eval_pearson = 0.1785468733027603
eval_spearmanr = 0.18945952641568345
eval_runtime = 3.1986
eval_samples_per_second = 120.992
epoch = 10.0
```
## Expected behavior
Are there any tips to update my own script, which is written for v4.1.1, to be applied to v4.6.0+?

] | 1,621 | 1,625 | 1,625 | NONE | null | Hi, community!
To better present how our community grows, we develop a tool to show contributors growing history on [https://github.com/api7/contributor-graph](https://github.com/api7/contributor-graph). Since we found it helpful, we think maybe if it could help some other community.
## WHAT IT IS
Basically, it just shows the contributors growth over time, just like the stargazers over time on the README. It would be the same with stars that we would update the graph each day, so the link would always present the real-time data. There is some other stuff to play around with if you would like to give it a try~
## HOW IT WORKS
We use Github API to get all commits, try to find the “Github way” to filter commits so the result data would be similar to Github, and then get the first commit time of each user.
Don't hesitate to tell us if there is a better place to present this graph other than this, or there are some other worries or other features you would like to have~🍻

substitutes faster list concatenation for get_length_grouped_indices() in LengthGroupedSampler and DistributedLengthGroupedSampler as prior sum(megabatches, []) is prohibitively slow for large number of megabatches (in test case takes hours for ~270k megabatches with 100 items each).

"Hi @NicoleJaneway ,\r\n\r\nI think this issue is similar to the following one in `ktrain` repo:\r\n\r\nhttps://github.com/amaiya/ktrain/issues/367\r\n\r\n\"Problem\" is, that there's no TensorFlow compatible model found on the hub (more precisely the `tf_model.h5` one). One good \"workaround\" would be if the model owner (pinging @EmilyAlsentzer here) would upload such a model to avoid these message :hugs: ",
"Thanks, @stefan-it! Unfortunately, with the 404 error, my app is no longer working. I posted a new [ktrain issue](https://github.com/amaiya/ktrain/issues/369) about it. In my experience, the creator has been amazingly responsive, so let's see what comes of the question.",
"Hello @NicoleJaneway, looking at the repository and its commit history, I don't think there ever was a `.h5` file uploaded.\r\n\r\nCould you share the code you're using when using local files so that we can see what's going on? If using local files, `transformers` should look locally before looking on the server, so you shouldn't get a 404 error",

] | 1,621 | 1,621 | 1,621 | NONE | null | I'm building a Named Entity Recognition (NER) model using the Hugging Face implementation of emilyalsentzer/Bio_ClinicalBERT. Up to today, I've had no issues with the model. Today it's not working as expected.
Question 1 - today, trying to train using:
MODEL_NAME = 'emilyalsentzer/Bio_ClinicalBERT'
model = text.sequence_tagger('bilstm-bert', preproc, bert_model=MODEL_NAME)
results in this error: 404 Client Error: Not Found for url: https://huggingface.co/emilyalsentzer/Bio_ClinicalBERT/resolve/main/tf_model.h5
Does Hugging Face offer any kind of health check to ascertain the status of their models?
Question 2 - working with files (model.h5, model.json, and preproc.sav) I'd saved from earlier training iterations, I'm getting the same 404 error shown above. I don't understand wherein these files the call to Hugging Face is occurring. It doesn't seem to be in the .json, and the .h5 and .sav file formats are hard to inspect. Read more about what these files are: https://medium.com/analytics-vidhya/how-to-deploy-your-neural-network-model-using-ktrain-ae255b134c77
Back in February, I'd used these exact model.h5, model.json, and preproc.sav files to run the NER app using Streamlit, no problem. Not sure if this is temporary issue with Bio_ClinicalBERT or if I need to retool my original approach due to potentially permanent problems with this transformer model. | {

"Hi! I believe you should be using `TransfoXLLMHeadModel` instead, as right now you're using the Transfo XL model without it's LM head.\r\n\r\nThe TransfoXL model is one of our older models which doesn't fit one-to-one with other models, unfortunately. I invite you to take a look at the signature here: https://huggingface.co/transformers/model_doc/transformerxl.html#transformers.TransfoXLLMHeadModel.forward\r\n\r\nIt doesn't accept the `attention_mask` parameter, so you would need to tell the tokenizer it doesn't need to output those. The easiest way you can achieve that is by changing the following line:\r\n\r\n```diff\r\n- tokenizer = PreTrainedTokenizerFast(tokenizer_file=\"espertransXL.json\")\r\n+ tokenizer = PreTrainedTokenizerFast(tokenizer_file=\"espertransXL.json\", model_input_names=[\"input_ids\"])\r\n```",

I made those changes and while that error is resolved, I am getting the error `KeyError: 'loss'` \r\n On searching the internet, it seems that this error comes when `labels` are not defined, but I believe I have defined it. \r\nI have created this public notebook for transformerXL https://colab.research.google.com/drive/1vMVoPhtkHFC_-0X-hgwHvH03ynGT0j5i?usp=sharing .

] | 1,621 | 1,698 | 1,625 | NONE | null | Hello, I am trying to recreate this notebook https://colab.research.google.com/github/huggingface/blog/blob/master/notebooks/01_how_to_train.ipynb for transformer XL
I made changes to the tokenizer as follows
```
%%time

tokenizer.normalizer = normalizers.Sequence([NFD(), Lowercase(), StripAccents()])
tokenizer.pre_tokenizer = Whitespace()
bert_tokenizer.post_processor = TemplateProcessing(
single="[CLS] $A [SEP]",
pair="[CLS] $A [SEP] $B:1 [SEP]:1",
special_tokens=[
("[CLS]", 1),
("[SEP]", 2),

)
trainer = WordLevelTrainer(show_progress=True, special_tokens=["[UNK]", "[CLS]", "[SEP]", "[PAD]", "[MASK]"])
files = [str(x) for x in Path(".").glob("**/*.txt")]
tokenizer.train(files, trainer)
tokenizer.save("espertransXL.json")
```
and then loaded it into the FastTokenizer
```
from transformers import PreTrainedTokenizerFast

tokenizer._sep_token="[SEP]"
tokenizer._cls_token="[CLS]"
tokenizer._unk_token="[UNK]"
tokenizer._pad_token="[PAD]"

```
Post that, I instantiated the model
```
from transformers import TransfoXLConfig, TransfoXLModel
config = TransfoXLConfig()
model = TransfoXLModel(config=config)
```
Set up the data collator:
```
from transformers import DataCollatorForLanguageModeling
data_collator = DataCollatorForLanguageModeling(
tokenizer=tokenizer, mlm=True, mlm_probability=0.15
)
```
Setting up the trainer as follows
```
from transformers import Trainer, TrainingArguments
training_args = TrainingArguments(
output_dir="./TransfoXL",
overwrite_output_dir=True,
num_train_epochs=1,
per_gpu_train_batch_size=16,
save_steps=10_000,
save_total_limit=2,
prediction_loss_only=True,
)
trainer = Trainer(
model=model,
args=training_args,
data_collator=data_collator,
train_dataset=dataset,
)
```
When I execute:
```
%%time
trainer.train()
```
I get the following error:
```

"No we can't just add the new argument without checking the version, as it's probably not going to work anymore for earlier versions of datasets (that's why it's bad to do breaking changes :-P).\r\nIt seems like it's the way the Datasets library wants to be used, so I would leave the default behavior here and you can change the script locally for your use case.

"Makes sense, @sgugger - thank you - back to `datasets`"
] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | `datasets==0.1.6` introduced in-memory datasets, which unfortunately has no caching which makes it very slow to develop with as the dataset gets reprocessed on every run. Supposedly this should make things faster overall, but at this huge cost to us developers.
It's also inconsistent where some datasets behave in one way, others in another way. This is too magical, IMHO.
This PR adds `keep_in_memory=False`, to disable in-memory cache, but restores normal caching.
Perhaps adding a note in the example that the user can change it to `True` if they don't care for the slow startup?
Alternatively, if you believe that the new behavior is good, let's create an env var at `datasets` that will control that, so that we can turn off this painful behavior w/o needing to manually modify the code.
Fixes: https://github.com/huggingface/transformers/issues/11801
p.s. working on this one script on many fronts - and then will sync other scripts at once.

This PR adds the option to only log on one node when doing multinode training. This is controlled by the `is_local_process_zero` method, so I apply the switch there to avoid putting in multiple places.

As seen with @stas00, there is a bug in the current speed metrics reporting: training reports the number of training steps per second while evaluation and predict report the number of samples per second. After discussion we concluded that both are interesting, so this PR updates the Trainer to report both. | {

] | 1,621 | 1,624 | 1,624 | NONE | null | I use nn.Softmax(dim=-1) to softmax. I find different outputs.

} | [] | closed | false | null | [] | [] | 1,621 | 1,621 | 1,621 | NONE | null | Hi,
I am currently using BertForSequenceClassification for my project, to show some results regarding transfer performance on the GLUE Benchmark.
I wan't to do two things.
1. Add a seperate nn.Linear() head on top of the already fine-tuned BertForSequenceClassification model and train the entire model:
Input -> BERT_BASE_MODEL -> CLASSIFIER -> nn.Linear
2. Remove (or reinitialize) classifier head with random weights with |out_features| = |labels of the new task| of the classifier.layer of BertForSequenceClassification model and retrain it on the new task.
I have problem with 2. If I try to execute my script, I always get the following error.
I tried various things, but couldn't get the code work. I also searched for similar posts, but couldn't find one.

I am solving a text clustering problem by fine-tuning a trained BERT model. After seeing a number of articles on the subject, I decided to use the masking problem and the TFBertForMaskedLM model for fine-tuning. I was able to fine-tune the network on my set, and now I want to use the embbedings of this model to transform my set and feed into the clustering algorithm.
The question and problem is that the output of `bert_model.layers[0]` is `[None, max_len, emb_size]`, I get emb of each word, and I need emb of a document or sequence, any way out?

I'm having issues accessing the `cardiffnlp/twitter-roberta-base-emotion` model using:
```
task='emotion'
MODEL = f"cardiffnlp/twitter-roberta-base-{task}"
tokenizer = AutoTokenizer.from_pretrained(MODEL)

When I substitute another task, such as `task='sentiment'`, it works fine. I have also tried using the `cardiffnlp/twitter-roberta-base-emotion` model within an NLP framework (AdaptNLP) but got a `permission denied` error.

"Could this also be a fallback for `AutoTokenizer` when none of the children classes match?"
] | 1,621 | 1,623 | 1,623 | CONTRIBUTOR | null | # What does this PR do?
In this PR, I propose to add the features needed to use `PreTrainedTokenizerFast` as a standalone tokenizer. These features include:
1. The ability to save a `PreTrainedTokenizerFast` tokenizer. Until now, it was not possible to `save_pretrained` ( with default values in the method) a `PreTrainedTokenizerFast` initialized from a folder containing only the `tokenizer.json`, `tokenizer_config.json` and `special_tokens_map.json` files. An error was previously returned because the `save_vocabulary` method was not implemented, which is normal when trying to use a fast tokenizer alone as it has no slow version. This feature allows this kind of use:
```
from transformers import PreTrainedTokenizerFast
tokenizer = PreTrainedTokenizerFast.from_pretrained("SaulLu/bengali-tokenizer-v2")
tokenizer.save_pretrained("./local_tokenizer")
```
2. The ability to specify in the `config.json` file that the type of tokenizer to be loaded is `PreTrainedTokenizerFast` in order to be able to load a `PreTrainedTokenizerFast` with `AutoTokenizer`.
In this PR, I also propose the modification/addition of 3 types of tests:
- Modifications: This design change required the modification of common tests for tokenizers stored in the `tests/test_tokenization_common.py` file. To my knowledge, this is quite a different use as this is the first time a tokenizer will not have a slow/legacy version. The changes to `tests/test_tokenization_common.py` allow a test class derived from `TokenizerTesterMixin` to leave the `tokenizer_class` attribute set to None and to only set the `rust_tokenizer_class` attribute. In other words, the derived class will allow to test a tokenizer which would not have an associated slow/legacy version. As there were several possibilities to modify these tests, if you ever think that it is easier to develop these tests in another PR, I can remove this part from this PR.
- Added : Added tests for using a standalone `PreTrainedTokenizerFast` in the `tests/test_tokenization_fast.py` file. I have created a tokenizer for this and stored it [here](https://huggingface.co/robot-test/dummy-tokenizer-fast).
- Added : Added tests to load a standalone `PreTrainedTokenizerFast` via `AutoTokenizer` in the `tests/test_tokenization_auto.py ` file. I have created a tokenizer for this and stored it [here](https://huggingface.co/robot-test/dummy-tokenizer-fast-with-model-config).
This PR should make it easy to use a fast tokenizer created with the `Tokenizers` library in the `Transformers` library. A typical use case would be :
1. Create a tokenizer with `Tokenizers` library
```
from tokenizers import Tokenizer
from tokenizers.models import BPE
from tokenizers.trainers import BpeTrainer
from tokenizers.pre_tokenizers import Whitespace
tokenizer = Tokenizer(BPE(unk_token="[UNK]"))
trainer = BpeTrainer(special_tokens=["[UNK]", "[CLS]", "[SEP]", "[PAD]", "[MASK]"])
tokenizer.pre_tokenizer = Whitespace()
files = [...]
tokenizer.train(files, trainer)
```
2. Adapt the tokenizer to `Transformers` library
At the end of this step, the tokenizer will be saved in a folder named `brand_new_tokenizer` and containing `tokenizer.json`, `tokenizer_config.json` and `special_tokens_map.json` files.
a. Save and initialize `PreTrainedTokenizerFast` with json file
```
tokenizer.save("tokenizer.json")
```
```
from transformers import PreTrainedTokenizerFast
from transformers.tokenization_utils import AddedToken
fast_tokenizer = PreTrainedTokenizerFast(
tokenizer_file="tokenizer.json",
model_max_length=512,
padding_side="right",
mask_token=AddedToken("[MASK]", lstrip=True, rstrip=False
)
fast_tokenizer.save_pretrained("brand_new_tokenizer")
```
b. Initialize `PreTrainedTokenizerFast` from the tokenizer object
```
from transformers import PreTrainedTokenizerFast
from transformers.tokenization_utils import AddedToken
fast_tokenizer = PreTrainedTokenizerFast(
tokenizer_object=tokenizer,
model_max_length=512,
padding_side="right",
mask_token=AddedToken("[MASK]", lstrip=True, rstrip=False
)
fast_tokenizer.save_pretrained("brand_new_tokenizer")
```
3. Load tokenizer with `PreTrainedTokenizerFast`
```
from transformers import PreTrainedTokenizerFast
tokenizer = PreTrainedTokenizerFast.from_pretrained("brand_new_tokenizer")
```
4. (Temporary solution before a next PR) Create a `config.json` file in `brand_new_tokenizer` folder and initialize a tokenizer with `AutoTokenizer`.
Config file:
```
{
"model_type": "albert",
"tokenizer_class": "PreTrainedTokenizerFast"
}
```
```
from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("brand_new_tokenizer")
```
In one (or more) next PRs, we would still have to :
- disassociate the tokenizer from the `config.json` file so that `AutoTokenizer` can load a saved tokenizer without a model
- if necessary adjust the documentation (for example [here](https://huggingface.co/transformers/fast_tokenizers.html) )

### Who can help
@patrickvonplaten (issue with "bert-base-uncased" checkpoint)
## Information
Model I am using (Bert, XLNet ...): BERT(base, uncased)
The problem arises when: loading "bert-base-uncased" model weights from state_dict
## To reproduce
Steps to reproduce the behavior:
1. Download model checkpoint from hub:
```
git lfs install
git clone https://huggingface.co/bert-base-uncased
```
2. Load pre-trained model from checkpoint using `.from_pretrained` (this sort of works)
```python
import torch
from transformers import BertForPreTraining
model = BertForPretraining.from_pretrained('./bert-base-uncased')
"""
[Output]:
Some weights of BertForPreTraining were not initialized from the model checkpoint at ./bert-base-uncased and are newly initialized: ['cls.predictions.decoder.bias']
You should probably TRAIN this model on a down-stream task to be able to use it for predictions and inference.
"""
```
3. Re-load same weights, this time using `.load_state_dict`
```python
state_dict = torch.load('./bert-base-uncased/pytorch_model.bin')
model.load_state_dict(state_dict)
```
This fails and outputs:
```
RuntimeError: Error(s) in loading state_dict for BertForPreTraining:

```
## Expected behavior
Opening the checkpoint using `torch.load` then loading these weights using `model.load_state_dict` should result in matching all keys successfully (in particular here, all LayerNorm weights should be loaded).
## Solution?
The issue here seems to be that the weight and bias parameters in LayerNorm were renamed from gamma and beta previously but the bert-base-uncased checkpoint wasn't updated to reflect this change. I am using a somewhat older version of transformers / pytorch but this seems to be still the case in recent versions of both libraries. The test was done using the model checkpoint from the model hub on 21 May 2021. | {

"Hi, you're quite right with your diagnosis. The problem is that by default, the tokenizer creates a dict of Python lists, not Tensors. Our models don't really understand those list inputs, and so you get errors. \r\n\r\nYou already found the solution of converting those lists to TF Tensors or Numpy arrays, but there is an easier way - just tell the Tokenizer that you want array output. Then you will get the dict you want, and the rest of your code will work correctly. Here's an updated code sample that returns a dict of Numpy arrays instead:\r\n\r\n```\r\ntokenizer = transformers.BertTokenizer.from_pretrained('bert-base-uncased')\r\nmodel = transformers.TFBertModel.from_pretrained('bert-base-uncased')\r\nmodel(**tokenizer(['i, ne'], return_tensors='np'))\r\n```",

## Information
Model I am using (Bert, XLNet ...):
TFBertModel, BertTokenizer
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [x] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [x] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
Want to check what input BertModel will take, so I tested with code
```
tokenizer = transformers.BertTokenizer.from_pretrained('bert-base-uncased')
model = transformers.TFBertModel.from_pretrained('bert-base-uncased')
model(**tokenizer(['i, ne']))
```
This gives an error
```
File "C:\Users\liche\anaconda3\lib\site-packages\transformers\models\bert\modeling_tf_bert.py", line 887, in call
outputs = self.bert(
File "C:\Users\liche\anaconda3\lib\site-packages\tensorflow\python\keras\engine\base_layer.py", line 1012, in __call__
outputs = call_fn(inputs, *args, **kwargs)
File "C:\Users\liche\anaconda3\lib\site-packages\transformers\models\bert\modeling_tf_bert.py", line 645, in call
embedding_output = self.embeddings(

position_embeds = tf.tile(input=position_embeds, multiples=(input_shape[0], 1, 1))
IndexError: list index out of range
```

## Expected behavior
<!-- A clear and concise description of what you would expect to happen. -->
I think my code should produce something, but not an error. So I check the code and find that `input_ids` for `TFBertEmbedding` is a () shape Tensor. Then tracing back to where produce it, and I finally end at function `input_processing` in modeling_tf_utils.py, and find that input_ids are a list of five Tensors, each is a shape of ().
So here comes the problem. As shown in the documentation, `TFBertModel` takes input_ids as a type of `TFModelInputType`, which only accepts either Tensor or numpy array or a list of them. My tokenizer produces ` [[101, 1045, 1010, 11265, 102]]` as input_ids. If manually converting it whole to Tensor or numpy array, I will get a shape (1,5) variable and can be successfully fed to the model and get outputs. However, if directly fed the dict to the model (as the code above), since the model only accepts Tensor or numpy array type, so it will convert the list to a type it accepts. Then it doesn't correctly covert the whole list to tensor, instead, it converts each individual element, i.e. integers, as the accepted type. And after `input_processing`, not the list of Tensor is fed to `TFEmbedding` but each individual empty shape integer Tensor. And it raises the error.
It can be solved by converting it to Tensor as desired before calling the model but my code is logically correct, and expect it works. | {

## Information
Model I am using Bert:
When I run a code like this:
```
from transformers import AutoTokenizer, AutoModel
tokenizer = AutoTokenizer.from_pretrained('bert-base-chinese')
bert = AutoModel.from_pretrained('bert-base-chinese')
tokens = tokenizer(query, answer, padding=True, truncation=True, max_length=128, return_tensors="pt")
out = bert(**tokens)
```
where query and answer are both tensors with batch size 128
however, it consumes over 10G memory in this line of code, ```out = bert(**tokens)```, anyone knows why?
and in the next iteration, it consumes 20, 30, 40G memory...

] | 1,621 | 1,623 | 1,623 | CONTRIBUTOR | null | developing with `run_clm` is difficult since its startup is very slow - it rebuilds the dataset on each start.
@VictorSanh says it started to do that recently...
I think it's because it has to chunk the existing dataset into smaller pieces, it's a slow start everytime and it doesn't save these results.
So the original dataset has already been preprocessed, but it's not good enough for `run_clm.py`.
So I'm thinking perhaps for dev needs we need a dataset with short <512 entries? and then it could use it w/o additional preprocessing?
But I could be wrong I haven't investigated the reason for the slow start.
to reproduce:
```
USE_TF=0 python examples/pytorch/language-modeling/run_clm.py \
--model_name_or_path gpt2 \
--dataset_name "stas/openwebtext-10k" \
--output_dir output_dir \
--overwrite_output_dir \
--do_train \
--do_eval \
--max_train_samples 1000 \
--max_eval_samples 200 \
--per_device_train_batch_size 4 \
--per_device_eval_batch_size 4 \
--num_train_epochs 1 \
--warmup_steps 8 \
--block_size 64 \
--fp16 \
--report_to none
```
So look at the tqdm bars before training starts to see the symptom. And this is already a very truncated dataset.

### Who can help
Library:
- tokenizers: @LysandreJik
## Information
Model I am using camemBert https://huggingface.co/camembert-base.
The problem arises when using:
* [x ] the official example scripts:
``` python
from transformers import CamembertModel, CamembertTokenizer
# You can replace "camembert-base" with any other model from the table, e.g. "camembert/camembert-large".
tokenizer = CamembertTokenizer.from_pretrained("camembert-base")
camembert = CamembertModel.from_pretrained("camembert-base")
camembert.eval() # disable dropout (or leave in train mode to finetune)
import torch
# Tokenize in sub-words with SentencePiece
tokenized_sentence = tokenizer.tokenize("J'aime le camembert !")
```
## To reproduce
Steps to reproduce the behavior:
1. Install transformers
2. Run code
I get a AttributeError: 'NoneType' object has no attribute 'tokenize' Error as the tokenizer is None when I load from pre trained.

### Who can help
tokenizer: @LysandreJik
## Information
Model I am using (Bert, XLNet ...): GPT2
The problem arises when using:
* [ ] my own modified scripts: (give details below)
* [ ] my own task or dataset: (give details below) text generation
After upgrade to 4.6.1 (same error in 4.6.0), I have an error when I load tokenizer.
### What I have tried
I searched for a similar issue and thought that this is a possible duplicate of [this issue](https://github.com/huggingface/transformers/issues/11713), but there was no change after I apply the solution.
I uninstalled transformers and tokenizers package, reinstall those, and still there is the same issue.
## To reproduce

1. Import tokenizer (like below)
```
from transformers import (PreTrainedTokenizerFast,
GPT2Tokenizer,)

] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | This PR is addressing a need to:
1. be able to quickly whip up a model of any desired size for the big-science experiments.
2. be able to activate gradient checkpointing (later addition)
We already have the functionality to create a model instead of using a pretrained one, but there was no way to control its config - it would choose the defaults of the Config object, which is very doubtful is of any practical use.
This PR:
1. adds a new `PretrainedConfig` method: `update_from_string` so one can update from a string.
```
config.update_from_string("n_embd=10,n_head=5,scale_attn_weights=false,summary_type=super_cls_index")
```
plus test.
2. adds a new `ModelArguments` arg: `--config_overrides="n_embd=1024,n_head=16,n_layer=48,n_positions=102"` which overrides the default config
3. auto-logs the resulting model size e.g.:
```
Training new model from scratch - Total size=626.69M params
```
Usage:
```
PYTHONPATH=src python examples/pytorch/language-modeling/run_clm.py --dataset_name \
"stas/openwebtext-10k" --output_dir output_dir --overwrite_output_dir --do_train --do_eval \
--max_train_samples 10000 --max_eval_samples 1000 --per_device_train_batch_size 4 \
--per_device_eval_batch_size 4 --num_train_epochs 1 --warmup_steps 8 --block_size 64 --fp16 \
--report_to none --model_type gpt2 --tokenizer_name gpt2 \
--config_overrides "n_embd=1024,n_head=16,n_layer=48,n_positions=1024"
```
Only `run_clm.py` for this experiment.

The only issue is how to depend on `datasets` dev version, might have to wait for a new `datasets` release 1.6.3 to be able to merge such PR.
A new release should be made in the next few days I'm being told, so a PR can be made. | {

"Thanks a lot for looking at this optimization. It does look like a nice speedup! Do you want to open a PR with the suggested changes since you're the one who designed it?"
] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | Hi,
get_length_grouped_indices() in LengthGroupedSampler and DistributedLengthGroupedSampler is prohibitively slow for large number of megabatches (in my case takes hours for ~270k megabatches with 100 items each) due to slow list concatenation with sum(megabatches, []).
Concatenating the lists with sum() may be repeatedly reallocating memory with each successive concatenation (similar to performance issues with string concatenation).
[item for sublist in megabatches for item in sublist] approach appears to significantly improve speed for large megabatch number, especially for megabatches with larger number of items.
For example:
# 50,000 megabatches with 3 items each:
megabatches = [[1,2,3] for _ in range(50_000)]
%timeit [item for sublist in megabatches for item in sublist];
3.72 ms ± 75.5 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%timeit sum(megabatches, []);
7.66 s ± 31.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
------------------------------------------
# 100,000 megabatches with 3 items each:
megabatches = [[1,2,3] for _ in range(100_000)]
%timeit [item for sublist in megabatches for item in sublist];
8.03 ms ± 14.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
%timeit sum(megabatches, []);
29.6 s ± 36.3 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
------------------------------------------
# 100,000 megabatches with 100 items each:
megabatches = [list(range(100)) for _ in range(100_000)]
%timeit [item for sublist in megabatches for item in sublist];
208 ms ± 44.6 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
%timeit -r1 -n1 sum(megabatches, []);
44min 3s ± 0 ns per loop (mean ± std. dev. of 1 run, 1 loop each)
Thank you for your wonderful work and consideration of this edit. @sgugger | {

"That is true. `len(word_ref) != len(word)` is a heuristic that will work on tokenizers that use BPE `continuing_subword_prefix` concept.\r\n \r\nThe reality is that there is no consistent notion of a \"word\" within arbitrary tokenizers.\r\nThe `continuing_subword_prefix` in BPE that *can* be used makes the concept explicit but it's not in the case of GPT2 (and roberta-large) as they are supposed to be ByteLevel. (it is set to '').\r\n\r\nBecause of that, there cannot be any consistent manner to check for \"is_subword\" for these tokenizers.\r\n\r\nLet's take an example \"Hello thereHello\" with `roberta-large`.\r\n\r\n-> [ 0 31414 89 31414 2]\r\n\r\nWe have twice the same token (31414), one is not a subword, the second one is. So there can't be a perfect output in any case.\r\nToken 89 is really \" there\" the space isn't treated that differently any other characters.\r\n\r\nIs that clearer on why it fails in this use-case ?\r\n\r\nThat being said, if we can figure out a heuristic that works for both, it would be better indeed.\r\n",
"When I had a similar problem, I resolved it by checking the character before that word in the original string. In this case, if there is a space, we can include it to the word, tokenize it and join them into a single string. The `word_ref` would be changed like the follows:\r\n\r\n```python\r\nif start_ind > 0 and sentence[start_ind-1] == \" \":\r\n decoded_word_ref = \"\".join(self.tokenizer.tokenize(sentence[start_ind-1: end_ind]))\r\nelse:\r\n decoded_word_ref = sentence[start_ind:end_ind]\r\n```\r\n\r\n(I am replacing the identifier `word_ref` with `decoded_word_ref` to emphasize that it is reconstructed from the token ids and may not correspond to a valid substring in the original text)\r\nTherefore, the related code segment would be updated as follows:\r\n\r\n```python\r\n if start_ind > 0 and sentence[start_ind-1] == \" \":\r\n decoded_word_ref = \"\".join(self.tokenizer.tokenize(sentence[start_ind-1: end_ind]))\r\n else:\r\n decoded_word_ref = sentence[start_ind:end_ind]\r\n word = self.tokenizer.convert_ids_to_tokens([int(input_ids[idx])])[0]\r\n is_subword = len(decoded_word_ref) != len(word)\r\n\r\n if int(input_ids[idx]) == self.tokenizer.unk_token_id:\r\n word = decoded_word_ref\r\n is_subword = False\r\n``` \r\n\r\nNotice that, even if there were multiple whitespaces before the word, they should not cause an issue since each space would be tokenized as a separate token except the last one.\r\n\r\nAlternatively, we might use the decoded_word_ref only for determining the value of `is_subword`. After that, we can use the `word_ref` as before.\r\n",
"That wouldn't work because some byte-level tokenizers will use space as a postfix, not prefix for \"word-separation\". \r\nThis is where we would like to avoid many if conditions for every possible tokenizer.\r\n",

### Who can help
@Narsil , @LysandreJik
## Information
The problem is in TokenClassificationPipeline, in and [this](https://github.com/huggingface/transformers/blob/f4a0d6ff867e8a82a33d7a653e7d45372a463271/src/transformers/pipelines/token_classification.py#L269) and [that line](https://github.com/huggingface/transformers/blob/f4a0d6ff867e8a82a33d7a653e7d45372a463271/src/transformers/pipelines/token_classification.py#L273) .
Here the aim is to determine if the original word for that token is tokenized into multiple subwords or just a single one. The problem is some tokenizers (such as Roberta or GPT-2) tokenize the whitespace together with the subsequent word which causes a mismatch between the original word and the reconstructed word. Since we reconstruct from the tokenized input ids, a single-word token also includes a whitespace (unles it is not the first word in the sequence).
## To reproduce
Please, consider the following:
```python
from transformers import AutoTokenizer
word_ref = "Car"
tokenizer = AutoTokenizer.from_pretrained("roberta-base")
word = tokenizer.tokenize(" " + word_ref)[0]
print(word)
>>> ĠCar
is_subword = len(word_ref) != len(word)
print(is_subword)
>>> True
```
The problem I simulated occurs in my custom pipeline that inherits from TokenClassificationPipeline when I use Roberta tokenizer. I checked the tests for that pipeline and observed that a small Bert tokenizer is used. This can explain why this bug could not be catched as the Bert model tokenizes the spaces differently. If I recall correctly, it splits the words on the whitespaces, then tokenizes the words. In any case, the following result shows why Bert tokenizer does not suffer from the mentioned problem:
```python
from transformers import AutoTokenizer
word_ref = "Car"
tokenizer = AutoTokenizer.from_pretrained("bert-base-cased")
word = tokenizer.tokenize(" " + word_ref)[0]
print(word)
>>> Car
is_subword = len(word_ref) != len(word)
print(is_subword)
>>> False
```
Finally, this problem might be affecting other pipelines (or inference scripts etc.) that depends on the reconstructed tokens as well.

"@stas00 or @sgugger can chime in if I'm wrong, but I believe half-precision performance improvement is strongly tied to hardware: even hardware that handles half-precision like pascal GPUs may not see a speed increase with FP16 compared to FP32, and I believe it can have the opposite effect. Could you share your setup?\r\n\r\nYou can check this thread for a similar question: https://github.com/huggingface/transformers/issues/9179",

] | 1,621 | 1,622 | 1,622 | NONE | null | Hi,
I am encountering troubles in understanding why the half-precision version of the T5Encoder infers slower than the full-precision one.
## To reproduce
Starting with the `half`-precision.
```python
import torch
from transformers import T5EncoderModel, T5Tokenizer
import time
device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu')
seq="Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet."
seq = ' '.join([seq] * 50)
model = T5EncoderModel.from_pretrained('t5-large', cache_dir='model').to(device)
model = model.half()
model = model.eval()
tokenizer = T5Tokenizer.from_pretrained('t5-large', cache_dir='model')
token_timer = time.time()
tokens = tokenizer.batch_encode_plus(seq, add_special_tokens=True, padding='longest', return_tensors='pt')
end_token = time.time()
input_ids = tokens['input_ids'].to(device)
attention_mask = tokens['attention_mask'].to(device)
model_timer = time.time()
with torch.no_grad():
ignored = model(input_ids=input_ids,attention_mask=attention_mask)
end_timer = time.time()
print(f'Full process:\t{end_timer - token_timer}')
print(f'Model only:\t{end_timer - model_timer}')
print(f'Token only:\t{end_token - token_timer}')
```
To use the `full`-precision, just drop the `model = model.half()` line.
## The output
The `half`-precision:
```
Full process: 10.929700136184692
Model only: 3.4116599559783936
Token only: 7.5169923305511475
```
The `full`-precision:
```
Full process: 7.794144153594971
Model only: 0.23117947578430176
Token only: 7.562213897705078
```
First, I would expect that the half-precision model is faster but secondly what is more confusing to me is the time difference in `Model only`, which measures the time needed to execute the the `torch.no_grad()`-part.
Is there an implementation problem in the code snippet? | {

## Information
Model I am using (Bert, XLNet ...):
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [ x] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ x] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
1. Run the below code
```
from transformers import MBartForConditionalGeneration, MBart50TokenizerFast`
model = MBartForConditionalGeneration.from_pretrained("facebook/mbart-large-50-many-to-many-mmt")
tokenizer = MBart50TokenizerFast.from_pretrained("facebook/mbart-large-50-many-to-many-mmt")
article_hi = "संयुक्त राष्ट्र के प्रमुख का कहना है कि सीरिया में कोई सैन्य समाधान नहीं है"
article_en = "Let's try this again..."
article_sw = 'Mzozo wa Israeli na Palestina:Marekani imekuwa ikiilinda Israel na kuifanya kutogoopa kufanya lolote'
# translate Hindi to Swahili
tokenizer.src_lang = "hi_IN"
encoded_hi = tokenizer(article_hi, return_tensors="pt")
generated_tokens = model.generate(**encoded_hi, forced_bos_token_id=tokenizer.lang_code_to_id["sw_KE"])
output = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
print(output)
# translate English to Swahili
tokenizer.src_lang = "en_XX"
encoded_en = tokenizer(article_en, return_tensors="pt")
generated_tokens = model.generate(**encoded_en, forced_bos_token_id=tokenizer.lang_code_to_id["sw_KE"])
output = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
print(output)
#translate Swahili to English
tokenizer.src_lang = 'sw_KE'
encoded_sw = tokenizer(article_sw, return_tensors="pt")
generated_tokens = model.generate(**encoded_sw, forced_bos_token_id=tokenizer.lang_code_to_id["en_XX"])
output = tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
print(output)
```
## Expected behavior
Output is:
['U. N. head says there is no military solution in Syria']
["! Let's try this again..."]
['The Israeli Prime Minister in Palestine: He visited Israel and visited Israel on any day of the week. Read more']
The translation from Swahili to English works, but the translations to Swahili all end up in English.

## Information
Model I am using: EncoderDecoder with BERT
The problem arises when using:
* [x] the official example scripts: slightly modified/extended, see below
The tasks I am working on is:
* [x] my own task or dataset: just an example sentence from the docs
## To reproduce
Steps to reproduce the behavior:
1. Start with the example script from the [EncoderDecoder forward documenation](https://huggingface.co/transformers/model_doc/encoderdecoder.html#transformers.EncoderDecoderModel.forward)
2. Remove model training and model saving and loading steps (not relevant) and configure model to return attentions
3. Check shapes of cross attention outputs of generation and forward
```python

```
Furthermore, if `num_beams>1` all `num_beams*batch_size` cross attentions are returned even if `num_return_sequences == 1`.
```python
# continued from above...
# generation
generated = model.generate(input_ids, decoder_start_token_id=model.config.decoder.pad_token_id, return_dict_in_generate=True, output_attentions=True, num_beams=10)
generated_cross_attentions = generated.cross_attentions
# generated_cross_attentions contains 19 elements, maybe one for each generation step (generated.sequences has 20 elements)?
print(f"Elements in generation cross attention: {len(generated_cross_attentions)}")
# All of the contained cross attentions have shape (10,12,1,8)
for cross_attention in generated_cross_attentions:
print(f"Shapes in generation cross attention: {[gca.shape for gca in cross_attention]}")
print(f"Shape of the generated sequences: {generated.sequences.shape}")
Yields: torch.Size([1, 20])
```
## Expected behavior
A `Tuple of torch.FloatTensor (one for each layer) of shape (batch_size, num_heads, gen_sequence_length, sequence_length)`. Ideally the cross attentions batch size should match the batch size of the `generated.sequences`.
## Work arounds
Stacking the tuples and then concatting along the dimension which is 1 like this:
```python
torch.cat([torch.stack(ca) for ca in generated_cross_attentions], dim=-2)
```
yields such a tensor of the correct shape, is that the correct way to assemble it?
For the batch size issue I haven't found a work around yet. Is it possible to retain the beam indices of the selected beams from `generate`? `output_scores` is no help, because it has the same shape as `generated.sequences`.
Any help, ideas or pointers how to work around this are highly appreciated. | {

"After some more testing, the above seems to be because of local attention layers in GPT-Neo's default configuration. When specifying ```config = GPTNeoConfig(attention_types=[[[\"global\"], 24]])```, I get similar `past_key_values` as in GPT-2:\r\n```python\r\n# 0: (torch.Size([1, 16, 3, 128]), torch.Size([1, 16, 3, 128]))\r\n# 1: (torch.Size([1, 16, 3, 128]), torch.Size([1, 16, 3, 128])) \r\n# 2: (torch.Size([1, 16, 3, 128]), torch.Size([1, 16, 3, 128])) \r\n# 3: (torch.Size([1, 16, 3, 128]), torch.Size([1, 16, 3, 128])) \r\n# 4: (torch.Size([1, 16, 3, 128]), torch.Size([1, 16, 3, 128])) \r\n# ...\r\n```\r\n\r\nI do think the [documentation](https://huggingface.co/transformers/model_doc/gpt_neo.html#transformers.GPTNeoModel.forward) for `past_key_values` should be updated since it currently says: \"with each tuple having 2 tensors of shape (batch_size, num_heads, sequence_length, embed_size_per_head)\"",

] | 1,621 | 1,631 | 1,631 | NONE | null | I have been successfully using the GPT2LMHeadModel module for text generation for some time and I recently tried to reuse the code to generate with GPTNeoForCausalLM. Though the documentations appear identical, I get the error "ValueError: not enough values to unpack (expected 2, got 1)" for the line`output, past = self.model(context, past_key_values=past, use_cache=True).values()` (which works fine for GPT2).
Is this a bug or has the documentation been copied incorrectly? Would appreciate any tips for fixing.

] | 1,621 | 1,652 | 1,625 | MEMBER | null | This PR aims at reworking the way the ONNX export tool work by introducing a static, checked description format to provide ONNX exporters (pt almost done, TF will follow) all the required knobs.
More specifically this PR introduces the following concepts:
- `OnnxConfig` dataclass which enforces a model to be supported to describe all the properties to generate proper export
- `OnnxVariable` namedtuple which describe a variables w.r.t the name of the variable, shape and potentially how many time it's "repeated" => Useful for `past_keys`
Test case was done initially for BART model, without `use_cache=True` supports.
For the sake of completeness, dropping support for `use_cache=True` is currently needed because we have a double nested tuple at the core of the `past_keys` output structure which would require multiple level of dynamic axis, not currently supported by ONNX.
This might be something we can work on in the future, potentially introducing a ONNX compatible output structure getting rid of the nested tuples layout and activable from a config property (_to be discussed further later on_).
**Update 1:**
- I managed to enable exporting with nested structures such as `past_key_values` for GPT2.
- Need to work on enabling the same for using such values as inputs to the model
Supported models:
- [x] ALBERT
- [x] BART (with & without past)
- [x] BERT
- [x] DistilBERT
- [ ] Longformer => I've support for this, but the exporting fails because of missing ops ... need investigations.
- [x] GPT2 (with & without past)
- [x] Roberta
- [x] T5
- [x] XLM-Roberta | {

" Hey @seongminp,\r\n\r\nThanks for the issue report. It's a rather specific use-case to pass `past_key_values` to `generate()`. Could you give me some more detail when you need to do so? ",
"Hi @patrickvonplaten!\r\n\r\nMy use-case for passing `past_key_values` to `generate` is to manipulate the encoder hidden states before passing them to decoder's cross attention. \r\n\r\nSpecifically, I am using a encoder-decoder generative (as in modeling the latent space, like GAN or VAE) text model. \r\n\r\nSeveral existing works, like [Microsoft's Optimus](https://github.com/ChunyuanLI/Optimus) and [Fang et al.](https://arxiv.org/abs/2101.00828), adds custom manipulations for key/value of decoder's cross attention.\r\n\r\nOfficial implementations of Optimus and Fang et al. are both implemented with this wonderful library, but uses a custom `generate` function because right now restrictions mentioned in this issue exists while passing `past` to `generate`.\r\n\r\nWould love to hear your feedback!",
"Hey @seongminp,\r\n\r\nThanks for the feedback! The problem is that the `past` variable strongly varies from model to model. *E.g.* Bart uses a different `past` tuple structure then `gpt2` does and `xlnet` uses a completely different structure. We would have to add a specific `prepare_cache` method to each model which seems would add to much complexity to the `generate()` method for quite a specific case IMO. Do you think we could instead solve it by just forcing the user to preprocess `past` correctly before passing it to `generate()`? E.g., the following code:\r\n\r\n```python\r\n past = tuple( \r\n (\r\n layer[0].index_select(0, expanded_return_idx).to(layer[0].device), \r\n layer[1].index_select(0, expanded_return_idx).to(layer[1].device), \r\n ) \r\n for layer in past \r\n)\r\n```\r\n\r\n could be executed by the user before calling `model.generate(input_ids, past=past)` no? \r\nWe could make a nice forum post about it so that people interested in the work mentioned above would have access to the correct pre-processing of `past` :-) \r\n\r\nWhat do you think?\r\n\r\n",
"Hi again.\r\n\r\nThat makes more sense.\r\n\r\nTrying to encompass all uses of `past` in `generate_utils` seems to be more trouble than it is worth. \r\n\r\nI'll close the pull request. Feel free to close this issue also!\r\n",
"This issue has been automatically marked as stale because it has not had recent activity.

```python
import torch
from transformers import BartForConditionalGeneration, BartConfig
config = BartConfig.from_pretrained('facebook/bart-base')
bart = BartForConditionalGeneration.from_pretrained('facebook/bart-base', config=config)
batch_size = 4
input_ids = torch.zeros((batch_size, 1), dtype=torch.long)
attention_mask = torch.ones((batch_size, 1))
# past_key_value: tuple of length config.n_layers with each tuple having 2 tuples each,
# of which has 2 tensors of shape (batch_size, num_heads, sequence_length - 1, embed_size_per_head)
embed_size_per_head = config.d_model // config.decoder_attention_heads
keys = torch.ones(config.decoder_layers, batch_size, config.decoder_attention_heads, 1, embed_size_per_head)
past = tuple((key, key) for key in keys)
# Works.
num_beams = 1
encoder_outputs = bart.get_encoder()(input_ids.repeat_interleave(num_beams, dim=0), return_dict=True)
bart.generate(input_ids=input_ids, attention_mask=attention_mask, encoder_outputs=encoder_outputs,past=past, use_cahce=True, num_beams=num_beams)
# Doesn't work.
num_beams = 3
encoder_outputs = bart.get_encoder()(input_ids.repeat_interleave(num_beams, dim=0), return_dict=True)
bart.generate(input_ids=input_ids, attention_mask=attention_mask, encoder_outputs=encoder_outputs, past=past, use_cahce=True, num_beams=num_beams)
```
## Expected behavior
<!-- A clear and concise description of what you would expect to happen. -->
In the code snippet above, second call to `generate` crashes because `past_key_values` are not supplied to all beams.
This happened when `past` argument is passed to `generate` in models where `is_encoder_decoder` is `True` (issue seen in Bart and T5).
To mitigate this issue, `past` should also be expanded in `_expand_inputs_for_generation` in `generation_utils.py`. (I've noticed that, at this point in the generation process, the script looks for `past` not `past_key_values` in `model_kwargs`.)
I've submitted a pull request that applies the above mentioned patch.

"Yes the change was unintentional to enable multi-label regression. I think the old\r\n```\r\nloss = loss_fct(logits.view(-1), labels.view(-1))\r\n```\r\nwill work in the case of one or several labels but might not give a clear error message if we have multiple labels but a shape error (if we have 5 possible lables but the model was configured with 4, we would see, with a batch size of 8, an error saying shape incompatibility between a tensor of size 32 and a tensor of size 40).\r\n\r\nSomething that would give a nicer error message is probably:\r\n```\r\nif self.num_labels == 1:\r\n loss = loss_fct(logits.squeeze(), labels.squeeze())\r\nelse:\r\n loss = loss_fct(logits, labels)\r\n```\r\nwhich would take care of this problem and show a clear error message.\r\n\r\nI can implement that change quickly and we should do a patch release but want to check the fix seems ok. What do you think @LysandreJik and @abhi1thakur ?",
"Thank you @sgugger for your prompt response!\r\nI also found #11583 reports a weird result with STS-B and could be fixed by the patch.",
"Indeed, I don't know why I couldn't reproduce the bad results earlier but this is definitely the same issue (I probably wasn't trying on the master branch.)"
] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | The recent PR #11012 changed the interface of forward function for `labels` in regression tasks as it skips `.view(-1)` in loss function like [this](https://github.com/huggingface/transformers/pull/11012/files#diff-a48ba7f6444ca4954a58f1ac3e66c7941a2bbc4615649d56b182aeac8cc36d9cL1523).
As shown below, that causes `UserWarning: Using a target size (torch.Size([32])) that is different to the input size (torch.Size([32, 1]))` with BERT in glue example code, and it looks like this change was applied **not only to BERT but also a lot of models in #11012**
To resolve it, the current example glue code needs `if` statement that transform `labels` variable before `forward` function only for regression task.
But if the interface change in the PR was unintentional, I think we should revert `.view(-1)` in loss function.

## Information
Model I am using (Bert, XLNet ...): `bert-base-uncased`
The problem arises when using:
* [x] the official example scripts: (give details below)
* [ ] my own modified scripts: (give details below)
The tasks I am working on is:
* [x] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
1. Run
```
mkdir /tmp/stsb/ -p
python transformers/examples/pytorch/text-classification/run_glue_no_trainer.py \
--model_name_or_path bert-base-cased \
--task_name stsb \
--max_length 128 \
--per_device_train_batch_size 32 \
--learning_rate 2e-5 \
--num_train_epochs 3 \
--output_dir /tmp/stsb/
```
2. We will see `UserWarning: Using a target size (torch.Size([32])) that is different to the input size (torch.Size([32, 1])). This will likely lead to incorrect results due to broadcasting. Please ensure they have the same size.` which didn't appear with the previous version of transformers like 2-3 weeks ago.

As a result, this gave me a pretty bad performance `epoch 2: {'pearson': 0.4408745967619131, 'spearmanr': 0.43830345183360847}` while they were both around 0.87 with the previous version.

## Expected behavior
The following warning (actually should be a bug) should not appear, and the validation performance pearson and spearmanr should be around 0.87 with the parameters given in the example command.
`UserWarning: Using a target size (torch.Size([32])) that is different to the input size (torch.Size([32, 1])). This will likely lead to incorrect results due to broadcasting. Please ensure they have the same size.`

"my reason for removing (still keeping a descriptive error obviously) rather than deprecating is that I'd love to know if people actually use those (and if they do, do they use them in scripts or manually)\r\n\r\nBut I will defer to the great transformers-maintainers as the final decision 💖",

] | 1,621 | 1,621 | 1,621 | MEMBER | null | Commands that are both in the `transformers-cli` and in the `huggingface-cli` are deprecated here and will be quickly removed.
I'm voting for deprecating them and not removing them even though better ways exist as I suspect some users to use the `transformers-cli` in bash scripts to automatically upload models to the hub.
Context from @julien-c:
> my thoughts is that we should deprecate the subset of transformers-cli command that are in huggingface-cli, as the commands are identical and having both is confusing.
>
> Transformers-specific commands (model conversion, new model templating) can stay in transformers-cli.

"Hey @patrickvonplaten, I haven't implemented head masking for the `generate` method for LED and T5 intentionally. The reason is that TF LED and T5 does not use head masks properly (there's an old glitch that the decoder uses encoder's `head_mask` instead of `cross_attn_head_mask`).

Is there any step-by-step tutorial regarding this task?

"Basically prior to this change you were running a single jitted function in each train step, and because of asynchronous dispatch it didn't have to wait until the previous step was complete until dispatching the program for the next step. But if you split an RNG in between, then JAX blocks until the previous step was complete, then dispatches and executes the split command, and then dispatches the next training step.\r\n\r\nIn short, the guideline is that each step in a training loop should be a single jitted function. If done right this should lead to close to 100% device utilization.\r\n\r\nThis is a common gotcha -- people hit this regularly, and we should help catch the slow patterns early, such that you could detect this even with a local run with no accelerator/unit test. @jheek is working on a library that would allow you to annotate code such that you'd get that kind of error or warning for this, and other cases.\r\n\r\n@jheek also said:\r\n\r\nYeah this is an example of my number 1 most common and most hurtful JAX performance gotcha that I want to catch automatically\r\n\r\nIn this case it stands out but there are more subtle variants where it's hard to spot in a review\r\n\r\nThis analysis is only true for TPU without async mode enabled btw. Because all other devices have a queue that is > 1\r\n",
"Thanks a lot for this in-detail explanation @avital! \r\n\r\nAlso pinging @sgugger @stas00 @mfuntowicz - might be interesting to read :-) ",

"Great that you discovered this! I actually didn't notice the bug, and since training was already fast enough I didn't look into it. Curious to see whether we will get even more speedup!",
"Reran, the experiments - got a small speed-up on TPU. Here the new numbers: https://github.com/huggingface/transformers/tree/master/examples/flax/text-classification#runtime-evaluation"
] | 1,621 | 1,621 | 1,621 | MEMBER | null | @avital @marcvanzee - I wanted to align `run_mlm_flax.py` more with `run_glue_flax.py` and noticed that by doing the change as shown in this PR, training on TPU slows down very significantly by ca. ~40%.
Currently, [`run_glue_flax.py`](https://github.com/huggingface/transformers/blob/master/examples/flax/text-classification/run_flax_glue.py) and [`run_mlm_flax.py`](https://github.com/huggingface/transformers/blob/master/examples/flax/language-modeling/run_flax_mlm.py) deal slightly differently with the PRNG key: `run_mlm_flax.py` splits the key inside the training step while `run_glue_flax.py` does so before the train step and shards it then before passing it to the train loop. It seems that `run_mlm_flax.py` is significantly faster on TPU.
Do you by any chance have good explanations for that? | {

### Who can help
@LysandreJik @patrickvonplaten @stas00 @sgugger
## Information
Model I am using (Bert, XLNet ...): DEBERTA, but which model is used is not important here.
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [ ] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
1. Train with trainer for more than 200k steps with save_total_limit to 50 for example, and logging steps to 200.
2. Observe how this bug makes you lose your most recent progress and it removes your newest checkpoints, which costs money, as you have been training without saving the newest checkpoints (it removes them just after saving them).
## Expected behavior
It is expected that the trainer doesn't remove the newest checkpoints, but the oldest ones, when you set the save_total_limit. This happens over 200k steps. | {

"Yes merging it was a mistake. It will be removed when we have something better in the future.",
"@sgugger Could you please tell me how could I adapt it for a general fast tokenizer? Or at least how would you do it for a ByteBPETokenizer like Roberta's or Deberta's?",
"I haven't dug into this, but it should probably leverage the `word_ids` the fast tokenizer provide to be more general.",
"This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.\n\nPlease note that issues that do not follow the [contributing guidelines](https://github.com/huggingface/transformers/blob/master/CONTRIBUTING.md) are likely to be ignored.",
"I just ran into the same problem. Is somebody working on this?\r\n\r\nI need a language modeling data collator for RoBERTa-style tokenizers and might as well try my hand at providing an extensible, general implementation that issues proper warnings if used on yet-unsupported tokenizer classes, if there's interest.",
"The problem is that after passing through datasets, the objects are dicts, not BatchEncoding, therefore they don't have the word_ids() method, and without that we cannot generalize Whole Word Masking. One solution is to pre tokenize and pre process the dataset inside the function you put in the datasets map, however you disable dynamic batching which is a key improvement of Roberta with respect to Bert.",
"Thank you for elaborating!\r\n\r\nSimilarly to the implementation for BERT tokenizers in the current `DataCollatorForWholeWordMasking`, it is possible to obtain a word start mask for RoBERTa tokenizers by decoding every token in the collator by using something like this:\r\n\r\n```python\r\ndef _word_starts(self, inputs: torch.Tensor) -> torch.Tensor:\r\n is_word_start = torch.full_like(inputs, fill_value=False)\r\n for i, example in enumerate(torch.split(inputs, split_size_or_sections=1, dim=0)):\r\n line_mask = torch.tensor([self.tokenizer.decode([t]).startswith(\" \") for t in example.flatten().tolist()\r\n if t != self.tokenizer.pad_token_id])\r\n is_word_start[i, 0:line_mask.shape[0]] = line_mask\r\n return is_word_start\r\n```\r\n\r\nI believe that this is accurate if the tokenizer is initialized with `add_prefix_space=True`, otherwise the first word is missing, which is probably acceptable in most circumstances.\r\n\r\nIf this method is correct, it could be extended to BART tokenizers, where the condition for the first token of a word is `not tokenizer.decode([t]).startswith('##')`. I'm not sure whether this is a path one wants to take here, though."

## Information
Model I am using (Bert, XLNet ...): DBERTA (V1) BASE
The problem arises when using:
* [x] the official example scripts: (give details below): DataCollatorForWholeWordMask
* [ ] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
## To reproduce
The DataCollatorForWholeWordMask, that should be used for pre-training a Roberta model, or a Deberta model for example (as you don't have a SpanCollator), only works for BERT, and one needs to look the details in the collator code to notice this. I've been training a language model from scratch for weeks now, just to notice yesterday that your collator for WholeWordMask is wrong and only works for BERT.
Steps to reproduce the behavior:
1. Try to use the DataCollatorForWholeWordMask with any model that is not BERT.
## Expected behavior
A data collator that is included in your data collators should work generally for any model, not only for BERT. Or at least, in the Docstring it should be clear that one will waste huge amounts of money if using this collator for other models that are not BERT. This being said, I would like to know how could I use the word_ids from the tokenizer to do this, as with the TokenClassification example you provide here: https://colab.research.google.com/github/huggingface/notebooks/blob/master/examples/text_classification.ipynb#scrollTo=MOsHUjgdIrIW
In this example the extension of the token labels doesn't depend on the continuation token having "##" at the beginning, but uses the word ids from the FastTokenizer. I think the DataCollatorForWholeWordMask should work generally, at least for all fast tokenizers, not only for BERT. For my case, I would like to know what can I do to at least train a little bit more with the correct objective, not with normal MLM but with WWMLM. | {

In [modeling_encoder_decoder.py line435](https://github.com/huggingface/transformers/blob/680d181ce80070f89f0ebd49bf93ca29b24cd56b/src/transformers/models/encoder_decoder/modeling_encoder_decoder.py#L435), "encoder_outputs" need to behave as Iterable (and the encoder-decoder-model documentation request Tuple as argument).
But, around [line 463](https://github.com/huggingface/transformers/blob/680d181ce80070f89f0ebd49bf93ca29b24cd56b/src/transformers/models/encoder_decoder/modeling_encoder_decoder.py#L463), "encoder_outputs" need to behave something else.

] | 1,621 | 1,621 | 1,621 | CONTRIBUTOR | null | Hi, I'm using large train data (parquet format) and want to pass this as `IterableDataset` to `Trainer`.
I managed to make custom `IterableDataset`, but sadly it doesn't work.
```python

labels = str(row[4])
inputs = self.tokenizer(inputs, return_tensors="pt", padding=True, truncation=True)
self.input_ids = [i.clone().detach() for i in inputs.input_ids]
self.attention_mask = [i.clone().detach() for i in inputs.attention_mask]
if self.with_labels:
yield BatchEncoding({'input_ids': self.input_ids, 'attention_mask': self.attention_mask, 'labels': labels})

for batch in df.to_batches():
return map(self.process, zip(*batch.columns))

"Fill-mask is for encoder-only models like BERT and RoBERTa. The GPT-neo model is a decoder-only model that is capable of doing text generation. There's a `TextGenerationPipeline` available, so you might try that out. The documentation can be found [here](https://huggingface.co/transformers/main_classes/pipelines.html#transformers.TextGenerationPipeline).",
"I read through articles that this model can be used to do grammar checking? Please share relevant documentation for the same.",
"Yes it can do grammar checking similar to GPT-3, in a zero-shot manner. So you can for example try the following prompt:\r\n\r\n```\r\nOriginal: She no went to the market.\r\nStandard American English:\r\n```\r\n\r\nNormally, if GPT-neo is smart enough, it will then generate `She didn't go to the market.`\r\n\r\nThese big generation models like GPT-3 and GPT-neo can learn in a zero-shot manner, just by giving a few examples, and then ask the model what comes next. So in this case, I didn't even give one example, I asked the model directly for an answer. You can also first provide several examples (\"Original\" and \"Standard American English\" pairs) to the model, and then ask it to predict what comes next. ",
"Great, Can you please share some sample implementation on google collab notebook? ",
"I just copied the code sample from the [model card](https://huggingface.co/EleutherAI/gpt-neo-1.3B):\r\n\r\n```\r\nfrom transformers import pipeline\r\ngenerator = pipeline('text-generation', model='EleutherAI/gpt-neo-1.3B')\r\ngenerator(\"Original: She no went to the market. Standard American English: She didn't go to the market. Original: I loving eating pizza. Standard American English:\", do_sample=True, min_length=50)\r\n```",
"Isn't the text generation specific to generating new text with a given prompt?\r\nI tried using the same format as what you have provided and this was the response \r\nInput: `Original: She no went to the market. Standard American English:` \r\nOutput: `Original: She no went to the market. Standard American English: No, I didn’t go to the market yesterday.` \r\nThis completely changed the 3rd person to 1st person? is the format `Original:xxx Standard American English:` important and is this how it does the grammar correction?",
"Isn't the text generation specific to generating new text with a given prompt? => well, normally it is meant to generate new text given a prompt indeed. But as models like GPT-3 and GPT-neo are so powerful and are trained on a lot of data, they are capable of performing what the authors of GPT-3 call \"in-context learning\": this means that the model knows what to do just based on a given prompt. See the [GPT-3 paper](https://arxiv.org/abs/2005.14165) for more info. \r\n\r\nI've just tried it with GPT-3 and it works. However, GPT-neo doesn't seem as powerful. This is logical since GPT-3 has 175 billion parameters, whereas GPT-neo only has 1.3 billion (there's also a 2.7 billion variant available). \r\n\r\nMaybe you can try by giving more examples in the prompt. Sometimes it seems to work:\r\n\r\n\r\n",
"@NielsRogge What other [task-specific pipelines](https://huggingface.co/transformers/main_classes/pipelines.html) can I use the gpt-neo model with?",
"I think the GPT-neo models only support the `TextGenerationPipeline`. But do not that they can be used for summarization, you can just provide a text followed by \"TLDR:\", and then the model will generate a summary. ",

This PR refactores the SpecAugement implementation for Wav2Vec2 by fully relying on PyTorch instead of numpy.
1) The code is made more readable
- `attention_mask` is dropped since it's not required to treat masked batch indices differently
- Previously every batch_idx was forced to have the same number of masked indices (overlapping masked indices can lead to some batch_indices to have fewer masked indices). This is also not enforced here since it would make the function very dependend on the batch_size which is not good IMO. I don't see a reason why different batch_idx cannot have different # of masked indices. It was verified via training that the change does not lead to a performance drop.
2) Replacing a for loop with tensorized code lead to a 1% speed-up in training (not really noticeable thb)

"What do you think about `dtype` being hardcoded?\r\n\r\nWhile this is OK for now hardcoding dtype might be an issue down the road. For most NLP models inputs are int, but for example for wav2vec2 they are floats. \r\n\r\nAnd would this have an impact if the final usage is in fp16 for where you used `float`.\r\n\r\nWe can't derive the dtype from the model in this context. \r\n\r\nThoughts?\r\n\r\nThis is not a showstopper to merge this, but just something to consider - I'm sure we will cross the bridge if we encounter it."

This PR adds a subsection right before the list of supported models & the big table of supported frameworks for each model. Merging this PR would change the "welcome" doc page as follows:
and
The motivation for this PR is mainly to be able to better link to all supported models and framework. *E.g.* when asking which models are supported by Flax, it's nice to have a direct link instead of having to scroll down | {

I found that I broke the link by accidentally adding a newline (probably by my formatter) in #11650.
Here is a fix for that.
Sorry for any inconvenience.

### Who can help
@LysandreJik
## Information
The `word_to_tokens` method of `XLNetTokenizerFast` seems not behaving correctly.
## To reproduce
Code below for example
```py
batch_claim = [
['Colin', 'Kaepernick', 'became', 'a'],
['Tilda', 'Swinton', 'is', 'a', 'vegan', '.']
]
batch_evidence = [
['He', 'remained', 'the', 'team', "'s", 'starting', 'quarterback'],
['Katherine', 'Matilda', '`', '`', 'Tilda', "''", 'Swinton', '-LRB-', 'born', '5', 'November', '1960']
]
tokenizer = XLNetTokenizerFast.from_pretrained('xlnet-base-cased')
# tokenizer = RobertaTokenizerFast.from_pretrained('roberta-base', add_prefix_space=True)
tokenized = tokenizer(
batch_claim, batch_evidence,
padding=True, truncation='do_not_truncate', is_split_into_words=True, return_tensors='pt'
)
print(tokenized)
print(tokenized.word_to_tokens(0, 0, 0))
```
gives None. (Maybe it's because that `XLNetTokenizer` pads on the front that causes this misbehavior?)

## Information
Model I am using (Bert, XLNet ...):
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [ ] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [ ] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
1.
2.
3.
<!-- If you have code snippets, error messages, stack traces please provide them here as well.

## Expected behavior
<!-- A clear and concise description of what you would expect to happen. -->
Hi, I have found a strange thing in the IntSoftmax class of Ibert.
def forward(self, x, scaling_factor):
if not self.quant_mode:
return nn.Softmax(dim=-1)(x), None
x_int = x / scaling_factor
x_int_max, _ = x_int.max(dim=-1, keepdim=True)
x_int = x_int - x_int_max
exp_int, exp_scaling_factor = self.int_exp(x_int, scaling_factor)
# Avoid overflow
exp, exp_scaling_factor = self.act(exp_int, exp_scaling_factor)
exp_int = exp / exp_scaling_factor
exp_int_sum = exp_int.sum(dim=-1, keepdim=True)
factor = floor_ste.apply(2 ** self.max_bit / exp_int_sum)
exp_int = floor_ste.apply(exp_int * factor / 2 ** (self.max_bit - self.output_bit))
scaling_factor = 1 / 2 ** self.output_bit
return exp_int * scaling_factor, scaling_factor
The code above is the forward func of IntSoftmax. And the problem is that `exp, exp_scaling_factor = self.act(exp_int, exp_scaling_factor)` in which self.act is an instance of QuantAct of which the input should be real number, but the exp_int is a quant int number. Although the result of the trained model word well, I think this is not right. | {

My problem is that GPU usage gets increased at the beginning of each step. Although the usage gets decreased with the help of torch.cuda.empty_cache() and gc.collector() during training, OOM errors happened after a while.

## Information
Models I am using: wav2vec2 and MBart
The problem arises when using:
* [ ] the official example scripts: (give details below)
* [x] my own modified scripts: (give details below)
The tasks I am working on is:
* [ ] an official GLUE/SQUaD task: (give the name)
* [x] my own task or dataset: (give details below)
## To reproduce
Steps to reproduce the behavior:
1. Build e2e_model with the following classes: wav2vec2_learn_repr and e2emodel
2. Feed audio and translation under the requirement of the following data_collator.
3. Model training with Trainer.

Adds a Flax examples README. Pretty bare for now, but will include a link to Cloud TPU instructions once they are up.
I hope my use of relative links works well, but looking for feedback. The main goal here is to have a canonical link we can point to. Perhaps later this should live on the proper docs page but I thought a README is a fine first step.

Parallelize and deparallelize methods for distribution of attention modules across multiple GPUs.
## Motivation
Finetuning GPT Neo 2.7B model on 12 GB GPU gives out of memory error. Having a parallelize method would allow us to train that model by splitting attention modules across multiple GPUs of smaller VRAM.
## Your contribution
Considering [this line](https://github.com/huggingface/transformers/blob/daf0d6a97bb0225a2571a2612b8285e2c3913992/src/transformers/models/gpt2/modeling_gpt2.py#L522) in GPT2 code and the absence of doc for parallelize method in [GPT2 documentation](https://huggingface.co/transformers/model_doc/gpt2.html#gpt2model), wanted to know if these methods are still supported. If not, what is the recommended method for fine-tuning large transformer models like GPT-Neo?
If they are still supported, I can take up this task and submit PR for both methods as well as documentation fix.

As pointed out on the [forums](https://discuss.huggingface.co/t/checkpoint-missing-optimizer-pt-how-to-resume/6138) there is a problem in the way checkpoints are deleted currently when `save_total_limit` is set and `load_best_model_at_end` is True. Since the best checkpoint is switched with the last checkpoint, we end up deleting the last checkpoint instead of the oldest available one.
This PR fixes this issue and adds tests. | {

Hi, I am trying to fine-tune a dutch summarization algorithm. I used the [following ](https://github.com/huggingface/notebooks/blob/master/examples/summarization.ipynb) example notebook provided by huggingface.co.
To prepare the targets for the model, we need to tokenize them inside the as_target_tokenizer context manager. This will make sure the tokenizer uses the special tokens corresponding to the targets. This is achieved by running the following code:
```
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("facebook/mbart-large-cc25")
with tokenizer.as_target_tokenizer():
print(tokenizer(["Hello, this one sentence", "This is another sentence."]))
```
However, I get the following error:
```
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-24-0fc6af9091da> in <module>()
----> 1 with tokenizer.as_target_tokenizer():
2 print(tokenizer(["Hello, this one sentence", "This is another sentence."]))

3 frames
/usr/local/lib/python3.7/dist-packages/transformers/tokenization_utils_fast.py in convert_ids_to_tokens(self, ids, skip_special_tokens)
293 tokens = []
294 for index in ids:
--> 295 index = int(index)
296 if skip_special_tokens and index in self.all_special_ids:
297 continue
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'
```
How can I work around this TypeError? I am not a professional and this is actually the first time submitting any question at all.
Thanks in advance :) | {
