class VipLlavaConfig(PretrainedConfig):
r"""
This is the configuration class to store the configuration of a [`VipLlavaForConditionalGeneration`]. It is used to instantiate an
VipLlava model according to the specified arguments, defining the model architecture. Instantiating a configuration
with the defaults will yield a similar configuration to that of the VipLlava-9B.
e.g. [ybelkada/vip-llava-7b-hf](https://huggingface.co/ybelkada/vip-llava-7b-hf)
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
documentation from [`PretrainedConfig`] for more information.
Args:
vision_config (`VipLlavaVisionConfig`, *optional*):
Custom vision config or dict
text_config (`Union[AutoConfig, dict]`, *optional*):
The config object of the text backbone. Can be any of `LlamaConfig` or `MistralConfig`.
ignore_index (`int`, *optional*, defaults to -100):
The ignore index for the loss function.
image_token_index (`int`, *optional*, defaults to 32000):
The image token index to encode the image prompt.
projector_hidden_act (`str`, *optional*, defaults to `"gelu"`):
The activation function used by the multimodal projector.
projector_layernorm_eps (`float`, *optional*, defaults to 1e-05):
The layer norm epsilon of the projector layernorm
vision_feature_layers (`List[int]`, *optional*, defaults to `[-2, -5, -8, -11, 6]`):
The list of layers to select the vision features from.
Example:
```python
>>> from transformers import VipLlavaForConditionalGeneration, VipLlavaConfig, CLIPVisionConfig, LlamaConfig
>>> # Initializing a CLIP-vision config
>>> vision_config = CLIPVisionConfig()
>>> # Initializing a Llama config
>>> text_config = LlamaConfig()
>>> # Initializing a VipLlava vipllava-7b style configuration
>>> configuration = VipLlavaConfig(vision_config, text_config)
>>> # Initializing a model from the vipllava-7b style configuration
>>> model = VipLlavaForConditionalGeneration(configuration)

Auli.
This model inherits from [`FlaxPreTrainedModel`]. Check the superclass documentation for the generic methods the
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
etc.)
This model is also a Flax Linen
[flax.nn.Module](https://flax.readthedocs.io/en/latest/_autosummary/flax.nn.module.html) subclass. Use it as a
regular Flax Module and refer to the Flax documentation for all matter related to general usage and behavior.
Finally, this model supports inherent JAX features such as:
- [Just-In-Time (JIT) compilation](https://jax.readthedocs.io/en/latest/jax.html#just-in-time-compilation-jit)
- [Automatic Differentiation](https://jax.readthedocs.io/en/latest/jax.html#automatic-differentiation)
- [Vectorization](https://jax.readthedocs.io/en/latest/jax.html#vectorization-vmap)
- [Parallelization](https://jax.readthedocs.io/en/latest/jax.html#parallelization-pmap)
Parameters:
config ([`Wav2Vec2Config`]): Model configuration class with all the parameters of the model.
Initializing with a config file does not load the weights associated with the model, only the
configuration. Check out the [`~FlaxPreTrainedModel.from_pretrained`] method to load the model weights.
dtype (`jax.numpy.dtype`, *optional*, defaults to `jax.numpy.float32`):
The data type of the computation. Can be one of `jax.numpy.float32`, `jax.numpy.float16` (on GPUs) and
`jax.numpy.bfloat16` (on TPUs).
This can be used to enable mixed-precision training or half-precision inference on GPUs or TPUs. If
specified all the computation will be performed with the given `dtype`.
**Note that this only specifies the dtype of the computation and does not influence the dtype of model
parameters.**

[`~FlaxPreTrainedModel.to_bf16`].
"""
WAV_2_VEC_2_INPUTS_DOCSTRING = r"""
Args:
input_values (`jnp.ndarray` of shape `(batch_size, sequence_length)`):
Float values of input raw speech waveform. Values can be obtained by loading a `.flac` or `.wav` audio file
into an array of type `List[float]` or a `numpy.ndarray`, *e.g.* via the soundfile library (`pip install
soundfile`). To prepare the array into `input_values`, the [`AutoProcessor`] should be used for padding and
conversion into a tensor of type `jnp.ndarray`. See [`Wav2Vec2Processor.__call__`] for details.
attention_mask (`jnp.ndarray` of shape `(batch_size, sequence_length)`, *optional*):
Mask to avoid performing convolution and attention on padding token indices. Mask values selected in `[0,
1]`:
- 1 for tokens that are **not masked**,
- 0 for tokens that are **masked**.
[What are attention masks?](../glossary#attention-mask) .. warning:: `attention_mask` should only be passed
if the corresponding processor has `config.return_attention_mask == True`. For all models whose processor
has `config.return_attention_mask == False`, such as
[wav2vec2-base](https://huggingface.co/facebook/wav2vec2-base-960h), `attention_mask` should **not** be
passed to avoid degraded performance when doing batched inference. For such models `input_values` should
simply be padded with 0 and passed without `attention_mask`. Be aware that these models also yield slightly
different results depending on whether `input_values` is padded or not.
mask_time_indices (`jnp.ndarray` of shape `(batch_size, sequence_length)`, *optional*):
Indices to mask extracted features for contrastive loss. When in training mode, model learns to predict
masked extracted features in *config.proj_codevector_dim* space.
output_attentions (`bool`, *optional*):
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
tensors for more detail.
output_hidden_states (`bool`, *optional*):
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
more detail.
return_dict (`bool`, *optional*):
Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.

AdaFactor pytorch implementation can be used as a drop in replacement for Adam original fairseq code:
https://github.com/pytorch/fairseq/blob/master/fairseq/optim/adafactor.py
Paper: *Adafactor: Adaptive Learning Rates with Sublinear Memory Cost* https://arxiv.org/abs/1804.04235 Note that
this optimizer internally adjusts the learning rate depending on the `scale_parameter`, `relative_step` and
`warmup_init` options. To use a manual (external) learning rate schedule you should set `scale_parameter=False` and
`relative_step=False`.
Arguments:
params (`Iterable[nn.parameter.Parameter]`):
Iterable of parameters to optimize or dictionaries defining parameter groups.
lr (`float`, *optional*):
The external learning rate.
eps (`Tuple[float, float]`, *optional*, defaults to `(1e-30, 0.001)`):
Regularization constants for square gradient and parameter scale respectively
clip_threshold (`float`, *optional*, defaults to 1.0):
Threshold of root mean square of final gradient update
decay_rate (`float`, *optional*, defaults to -0.8):
Coefficient used to compute running averages of square
beta1 (`float`, *optional*):
Coefficient used for computing running averages of gradient
weight_decay (`float`, *optional*, defaults to 0.0):
Weight decay (L2 penalty)
scale_parameter (`bool`, *optional*, defaults to `True`):
If True, learning rate is scaled by root mean square
relative_step (`bool`, *optional*, defaults to `True`):
If True, time-dependent learning rate is computed instead of external learning rate
warmup_init (`bool`, *optional*, defaults to `False`):
Time-dependent learning rate computation depends on whether warm-up initialization is being used
This implementation handles low-precision (FP16, bfloat) values, but we have not thoroughly tested.
Recommended T5 finetuning settings (https://discuss.huggingface.co/t/t5-finetuning-tips/684/3):
- Training without LR warmup or clip_threshold is not recommended.
- use scheduled LR warm-up to fixed LR
- use clip_threshold=1.0 (https://arxiv.org/abs/1804.04235)
- Disable relative updates
- Use scale_parameter=False
- Additional optimizer operations like gradient clipping should not be used alongside Adafactor
Example:
```python
Adafactor(model.parameters(), scale_parameter=False, relative_step=False, warmup_init=False, lr=1e-3)
```
Others reported the following combination to work well:
```python
Adafactor(model.parameters(), scale_parameter=True, relative_step=True, warmup_init=True, lr=None)
```
When using `lr=None` with [`Trainer`] you will most likely need to use [`~optimization.AdafactorSchedule`]
scheduler as following:
```python
from transformers.optimization import Adafactor, AdafactorSchedule
optimizer = Adafactor(model.parameters(), scale_parameter=True, relative_step=True, warmup_init=True, lr=None)
lr_scheduler = AdafactorSchedule(optimizer)
trainer = Trainer(..., optimizers=(optimizer, lr_scheduler))
```
Usage:
```python
# replace AdamW with Adafactor
optimizer = Adafactor(
model.parameters(),
lr=1e-3,
eps=(1e-30, 1e-3),
clip_threshold=1.0,
decay_rate=-0.8,

This folder contains a template to add a tokenization test.
## Usage
Using the `cookiecutter` utility requires to have all the `dev` dependencies installed.
Let's first [fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo) the `transformers` repo on github. Once it's done you can clone your fork and install `transformers` in our environment:
```shell script
git clone https://github.com/YOUR-USERNAME/transformers
cd transformers
pip install -e ".[dev]"
```
Once the installation is done, you can generate the template by running the following command. Be careful, the template will be generated inside a new folder in your current working directory.
```shell script
cookiecutter path-to-the folder/adding_a_missing_tokenization_test/
```
You will then have to answer some questions about the tokenizer for which you want to add tests. The `modelname` should be cased according to the plain text casing, i.e., BERT, RoBERTa, DeBERTa.
Once the command has finished, you should have a one new file inside the newly created folder named `test_tokenization_Xxx.py`. At this point the template is finished and you can move it to the sub-folder of the corresponding model in the test folder.

Stand in the desert. . . . Near them, on the sand,
Half sunk a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them, and the heart that fed;
And on the pedestal, these words appear:
My name is Ozymandias, King of Kings;
Look on my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away

Utility that checks all docstrings of public objects have an argument section matching their signature.
Use from the root of the repo with:
```bash
python utils/check_docstrings.py
```
for a check that will error in case of inconsistencies (used by `make repo-consistency`).
To auto-fix issues run:
```bash
python utils/check_docstrings.py --fix_and_overwrite
```
which is used by `make fix-copies` (note that this fills what it cans, you might have to manually fill information
like argument descriptions).

# TRL - Transformer Reinforcement Learning
TRL is a full stack library where we provide a set of tools to train transformer language models with Reinforcement Learning, from the Supervised Fine-tuning step (SFT), Reward Modeling step (RM) to the Proximal Policy Optimization (PPO) step.
The library is integrated with 🤗 [transformers](https://github.com/huggingface/transformers).

# Use model after training
Once you have trained a model using either the SFTTrainer, PPOTrainer, or DPOTrainer, you will have a fine-tuned model that can be used for text generation. In this section, we'll walk through the process of loading the fine-tuned model and generating text. If you need to run an inference server with the trained model, you can explore libraries such as [`text-generation-inference`](https://github.com/huggingface/text-generation-inference).
## Load and Generate
If you have fine-tuned a model fully, meaning without the use of PEFT you can simply load it like any other language model in transformers. E.g. the value head that was trained during the PPO training is no longer needed and if you load the model with the original transformer class it will be ignored:
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
model_name_or_path = "kashif/stack-llama-2" #path/to/your/model/or/name/on/hub
device = "cpu" # or "cuda" if you have a GPU
model = AutoModelForCausalLM.from_pretrained(model_name_or_path).to(device)
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path)
inputs = tokenizer.encode("This movie was really", return_tensors="pt").to(device)
outputs = model.generate(inputs)
print(tokenizer.decode(outputs[0]))
```
Alternatively you can also use the pipeline:
```python
from transformers import pipeline
model_name_or_path = "kashif/stack-llama-2" #path/to/your/model/or/name/on/hub
pipe = pipeline("text-generation", model=model_name_or_path)
print(pipe("This movie was really")[0]["generated_text"])
```
## Use Adapters PEFT
```python
from peft import PeftConfig, PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer
base_model_name = "kashif/stack-llama-2" #path/to/your/model/or/name/on/hub"
adapter_model_name = "path/to/my/adapter"
model = AutoModelForCausalLM.from_pretrained(base_model_name)
model = PeftModel.from_pretrained(model, adapter_model_name)
tokenizer = AutoTokenizer.from_pretrained(base_model_name)
```
You can also merge the adapters into the base model so you can use the model like a normal transformers model, however the checkpoint will be significantly bigger:
```python
model = AutoModelForCausalLM.from_pretrained(base_model_name)
model = PeftModel.from_pretrained(model, adapter_model_name)
model = model.merge_and_unload()
model.save_pretrained("merged_adapters")
```
Once you have the model loaded and either merged the adapters or keep them separately on top you can run generation as with a normal model outlined above.

<jupyter_start><jupyter_text>Tune GPT2 to generate positive reviews> Optimise GPT2 to produce positive IMDB movie reviews using a BERT sentiment classifier as a reward function. Figure: Experiment setup to tune GPT2. The yellow arrows are outside the scope of this notebook, but the trained models are available through Hugging Face. In this notebook we fine-tune GPT2 (small) to generate positive movie reviews based on the IMDB dataset. The model gets the start of a real review and is tasked to produce positive continuations. To reward positive continuations we use a BERT classifier to analyse the sentiment of the produced sentences and use the classifier's outputs as rewards signals for PPO training.

""" trl is an open library for RL with transformer models.
Note:
VERSION needs to be formatted following the MAJOR.MINOR.PATCH convention
(we need to follow this convention to be able to retrieve versioned scripts)
Simple check list for release from AllenNLP repo: https://github.com/allenai/allennlp/blob/master/setup.py
To create the package for pypi.
0. Prerequisites:
- Dependencies:
- twine: "pip install twine"
- Create an account in (and join the 'trl' project):
- PyPI: https://pypi.org/
- Test PyPI: https://test.pypi.org/
1. Change the version in:
- __init__.py
- setup.py
2. Commit these changes: "git commit -m 'Release: VERSION'"
3. Add a tag in git to mark the release: "git tag VERSION -m 'Add tag VERSION for pypi'"
Push the tag to remote: git push --tags origin main
4. Build both the sources and the wheel. Do not change anything in setup.py between
creating the wheel and the source distribution (obviously).
First, delete any "build" directory that may exist from previous builds.
For the wheel, run: "python setup.py bdist_wheel" in the top level directory.
(this will build a wheel for the python version you use to build it).
For the sources, run: "python setup.py sdist"
You should now have a /dist directory with both .whl and .tar.gz source versions.
5. Check that everything looks correct by uploading the package to the pypi test server:
twine upload dist/* -r pypitest --repository-url=https://test.pypi.org/legacy/
Check that you can install it in a virtualenv/notebook by running:
pip install huggingface_hub fsspec aiohttp
pip install -U tqdm
pip install -i https://testpypi.python.org/pypi evaluate
6. Upload the final version to actual pypi:
twine upload dist/* -r pypi
7. Fill release notes in the tag in github once everything is looking hunky-dory.
8. Change the version in __init__.py and setup.py to X.X.X+1.dev0 (e.g. VERSION=1.18.3 -> 1.18.4.dev0).
Then push the change with a message 'set dev version'

r"""
KTOConfig collects all training arguments related to the [`KTOTrainer`] class.
Using [`HfArgumentParser`] we can turn this class into
[argparse](https://docs.python.org/3/library/argparse#module-argparse) arguments that can be specified on the
command line.
Parameters:
max_length (`int`, *optional*, defaults to `None`):
The maximum length of the sequences in the batch. This argument is required if you want to use the default data collator.
max_prompt_length (`int`, *optional*, defaults to `None`):
The maximum length of the prompt. This argument is required if you want to use the default data collator.
max_completion_length (`int`, *optional*, defaults to `None`):
The maximum length of the target. This argument is required if you want to use the default data collator and your model is an encoder-decoder.
beta (`float`, defaults to 0.1):
The beta factor in KTO loss. Higher beta means less divergence from the initial policy.
desirable_weight (`float`, *optional*, defaults to 1.0):
The desirable losses are weighed by this factor to counter unequal number of desirable and undesirable paris.
undesirable_weight (`float`, *optional*, defaults to 1.0):
The undesirable losses are weighed by this factor to counter unequal number of desirable and undesirable pairs.
label_pad_token_id (`int`, defaults to `-100`):
The label pad token id. This argument is required if you want to use the default data collator.
padding_value (`int`, defaults to `0`):
The padding value if it is different to the tokenizer's pad_token_id.
truncation_mode (`str`, defaults to `keep_end`):
The truncation mode to use, either `keep_end` or `keep_start`. This argument is required if you want to use the default data collator.
generate_during_eval (`bool`, defaults to `False`):
Whether to sample and log generations during evaluation step.
is_encoder_decoder (`Optional[bool]`, `optional`, defaults to `None`):
If no model is provided, we need to know if the model_init returns an encoder-decoder.
precompute_ref_log_probs (`bool`, defaults to `False`):
Flag to precompute reference model log probabilities for training and evaluation datasets. This is useful if you want to train
without the reference model and reduce the total GPU memory needed.
model_init_kwargs: (`Optional[Dict]`, *optional*):
Dict of Optional kwargs to pass when instantiating the model from a string.
ref_model_init_kwargs: (`Optional[Dict]`, *optional*):
Dict of Optional kwargs to pass when instantiating the ref model from a string.

# Big model inference benchmarks
Running inference with Accelerate on big models.
## Setup
These benchmarks use the `transformers` library:
```bash
pip install transformers
```
To reproduce or test a new setup, run
```py
python inference_acc.py model_name
```
This script supports `gpt-j-6b`, `gpt-neox`, `opt` (30B version) and `T0pp` out of the box, but you can specify any valid checkpoint for `model_name`.
To force a different `torch_dtype` than the one in the config: `--torch_dtype xxx`.
If you get an error linked to disk offload, you need to add the option `--disk-offload`
## Results
On a setup with two Titan RTXs (24GB of RAM) and 32GB of RAM, we get the following benchmarks (T0pp does not run in float16, which is why it's not included).
| Model | Model load time | Generation time | dtype | GPU 0 use | GPU 1 use | CPU use | Disk offload |
|:-----:|:---------------:|:---------------:|:-----:|:---------:|:---------:|:-------:|:------------:|
| GPT-J-6B | 8.7s | 0.05s per token | float16 | 11.7GB | 0GB | 0GB | no |
| GPT-J-6B | 12.4s | 0.06s per token | float32 | 21.9GB | 1.5GB | 0GB | no |
| GPT-Neo-X-20B | 30.9s | 0.08s per token | float16 | 21.5GB | 18GB | 0GB | no |
| GPT-Neo-X-20B | 78.2s | 10.72s per token | float32 | 20.3GB | 22.7 GB | 24.4GB | yes |
| T0pp (11B) | 29.4s | 0.05s per token | float32 | 21.1GB | 21.3GB | 0GB | no |
| OPT-30B | 34.5s | 2.37s per token | float16 | 20.7GB | 22.3GB | 14.1GB | no |
| OPT-30B | 112.3s | 33.9s per token | float32 | 20.2GB | 21.2GB | 23.5GB | yes |
Note on the results:
- using two GPUs instead of one does not slow down generation
- using CPU offload slows down a bit (see OPT-30b)
- using disk offload slows down a lot (need to implement prefetching)
You will also note that Accelerate does not use anymore GPU and CPU RAM than necessary:
- peak GPU memory is exactly the size of the model put on a given GPU
- peak CPU memory is either the size of the biggest checkpoint shard or the part of the model offloaded on CPU, whichever is bigger. | accelerate/benchmarks/README.md/0 | {

# Troubleshoot
This guide provides solutions to some issues you might encounter when using Accelerate. Not all errors are covered because Accelerate is an active library that is continuously evolving and there are many different use cases and distributed training setups. If the solutions described here don't help with your specific error, please take a look at the [Ask for help](#ask-for-help) section to learn where and how to get help.
## Logging
Logging can help you identify where an error is coming from. In a distributed setup with multiple processes, logging can be a challenge, but Accelerate provides the [`~accelerate.logging`] utility to ensure logs are synchronized.
To troubleshoot an issue, use [`~accelerate.logging`] instead of the standard Python [`logging`](https://docs.python.org/3/library/logging.html#module-logging) module. Set the verbosity level (`INFO`, `DEBUG`, `WARNING`, `ERROR`, `CRITICAL`) with the `log_level` parameter, and then you can either:
1. Export the `log_level` as the `ACCELERATE_LOG_LEVEL` environment variable.
2. Pass the `log_level` directly to `get_logger`.
For example, to set `log_level="INFO"`:
```py
from accelerate.logging import get_logger
logger = get_logger(__name__, log_level="DEBUG")
```
By default, the log is called on main processes only. To call it on all processes, pass `main_process_only=False`.
If a log should be called on all processes and in order, also pass `in_order=True`.
```py
from accelerate.logging import get_logger
logger = get_logger(__name__, log_level="DEBUG")
# log all processes
logger.debug("thing_to_log", main_process_only=False)
# log all processes in order
logger.debug("thing_to_log", main_process_only=False, in_order=True)
```
## Hanging code and timeout errors
There can be many reasons why your code is hanging. Let's take a look at how to solve some of the most common issues that can cause your code to hang.
### Mismatched tensor shapes
Mismatched tensor shapes is a common issue that can cause your code to hang for a significant amount of time on a distributed setup.
When running scripts in a distributed setup, functions such as [`Accelerator.gather`] and [`Accelerator.reduce`] are necessary to grab tensors across devices to collectively perform operations on them. These (and other) functions rely on `torch.distributed` to perform a `gather` operation, which requires tensors to have the **exact same shape** across all processes. When the tensor shapes don't match, your code hangs and you'll eventually hit a timeout exception.
You can use Accelerate's operational debug mode to immediately catch this issue. We recommend enabling this mode during the `accelerate config` setup, but you can also enable it from the CLI, as an environment variable, or by manually editing the `config.yaml` file.
<hfoptions id="mismatch">
<hfoption id="CLI">
```bash
accelerate launch --debug {my_script.py} --arg1 --arg2
```
</hfoption>
<hfoption id="environment variable">
If enabling debug mode as an environment variable, you don't need to call `accelerate launch`.
```bash
ACCELERATE_DEBUG_MODE="1" torchrun {my_script.py} --arg1 --arg2
```
</hfoption>
<hfoption id="config.yaml">
Add `debug: true` to your `config.yaml` file.
```yaml
compute_environment: LOCAL_MACHINE
debug: true
```
</hfoption>
</hfoptions>
Once you enable debug mode, you should get a traceback that points to the tensor shape mismatch issue.
```py
Traceback (most recent call last):
File "/home/zach_mueller_huggingface_co/test.py", line 18, in <module>

- Process 0: [1, 5]
- Process 1: [1, 2, 5]
```
### Early stopping
For early stopping in distributed training, if each process has a specific stopping condition (e.g. validation loss), it may not be synchronized across all processes. As a result, a break can happen on process 0 but not on process 1 which will cause your code to hang indefinitely until a timeout occurs.
If you have early stopping conditionals, use the `set_breakpoint` and `check_breakpoint` methods to make sure all the processes
are ended correctly.
```py
# Assume `should_do_breakpoint` is a custom defined function that returns a conditional,
# and that conditional might be true only on process 1
if should_do_breakpoint(loss):
accelerator.set_breakpoint()
# Later in the training script when we need to check for the breakpoint
if accelerator.check_breakpoint():
break
```
### Low kernel versions on Linux
On Linux with kernel version < 5.5, hanging processes have been reported. To avoid this problem, upgrade your system to a later kernel version.
### MPI
If your distributed CPU training job using MPI is hanging, ensure that you have
[passwordless SSH](https://www.open-mpi.org/faq/?category=rsh#ssh-keys) setup (using keys) between the nodes. This means
that for all nodes in your hostfile, you should to be able to SSH from one node to another without being prompted for a password.
Next, try to run the `mpirun` command as a sanity check. For example, the command below should print out the
hostnames for each of the nodes.
```bash
mpirun -f hostfile -n {number of nodes} -ppn 1 hostname
```
## CUDA Out-of-Memory
One of the most frustrating errors when it comes to running training scripts is hitting "CUDA Out-of-Memory". The entire script needs to be restarted and any progress is lost.
To address this problem, Accelerate provides the [`find_executable_batch_size`] utility that is heavily based on [toma](https://github.com/BlackHC/toma).
This utility retries code that fails due to OOM (out-of-memory) conditions and automatically lowers batch sizes. For each OOM condition, the algorithm decreases the batch size by half and retries the code until it succeeds.
To use [`find_executable_batch_size`], restructure your training function to include an inner function with `find_executable_batch_size` and build your dataloaders inside it. At a minimum, this only takes 4 new lines of code.
<Tip warning={true}>
The inner function **must** take batch size as the first parameter, but we do not pass one to it when called. The wrapper will handles this for you. Any object (models, optimizers) that consumes CUDA memory and is passed to the [`Accelerator`] also **must** be declared inside the inner function.
</Tip>
```diff
def training_function(args):
accelerator = Accelerator()
+ @find_executable_batch_size(starting_batch_size=args.batch_size)
+ def inner_training_loop(batch_size):
+ nonlocal accelerator # Ensure they can be used in our context
+ accelerator.free_memory() # Free all lingering references
model = get_model()
model.to(accelerator.device)
optimizer = get_optimizer()
train_dataloader, eval_dataloader = get_dataloaders(accelerator, batch_size)
lr_scheduler = get_scheduler(
optimizer,
num_training_steps=len(train_dataloader)*num_epochs
)
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
train(model, optimizer, train_dataloader, lr_scheduler)
validate(model, eval_dataloader)
+ inner_training_loop()
```
## Non-reproducible results between device setups
If you changed the device setup and observe different model performance, it is likely you didn't update your script when moving from one setup to another. Even if you're using the same script with the same batch size, the results will still be different on a TPU, multi-GPU, and single GPU.
For example, if you were training on a single GPU with a batch size of 16 and you move to a dual GPU setup, you need to change the batch size to 8 to have the same effective batch size. This is because when training with Accelerate, the batch size passed to the dataloader is the **batch size per GPU**.
To make sure you can reproduce the results between the setups, make sure to use the same seed, adjust the batch size accordingly, and consider scaling the learning rate.
For more details and a quick reference for batch sizes, check out the [Comparing performance between different device setups](../concept_guides/performance) guide.
## Performance issues on different GPUs
If your multi-GPU setup consists of different GPUs, you may encounter some performance issues:
- There may be an imbalance in GPU memory between the GPUs. In this case, the GPU with the smaller memory will limit the batch size or the size of the model that can be loaded onto the GPUs.
- If you are using GPUs with different performance profiles, the performance will be driven by the slowest GPU you are using because the other GPUs will have to wait for it to complete its workload.
Vastly different GPUs within the same setup can lead to performance bottlenecks.
## Ask for help
If none of the solutions and advice here helped resolve your issue, you can always reach out to the community and Accelerate team for help.
- Ask for help on the Hugging Face forums by posting your question in the [🤗 Accelerate category](https://discuss.huggingface.co/c/accelerate/18).

# Performing gradient accumulation with 🤗 Accelerate
Gradient accumulation is a technique where you can train on bigger batch sizes than
your machine would normally be able to fit into memory. This is done by accumulating gradients over
several batches, and only stepping the optimizer after a certain number of batches have been performed.
While technically standard gradient accumulation code would work fine in a distributed setup, it is not the most efficient
method for doing so and you may experience considerable slowdowns!
In this tutorial you will see how to quickly setup gradient accumulation and perform it with the utilities provided in 🤗 Accelerate,
which can total to adding just one new line of code!
This example will use a very simplistic PyTorch training loop that performs gradient accumulation every two batches:
```python
device = "cuda"
model.to(device)
gradient_accumulation_steps = 2
for index, batch in enumerate(training_dataloader):
inputs, targets = batch
inputs = inputs.to(device)
targets = targets.to(device)
outputs = model(inputs)
loss = loss_function(outputs, targets)
loss = loss / gradient_accumulation_steps
loss.backward()
if (index + 1) % gradient_accumulation_steps == 0:
optimizer.step()
scheduler.step()
optimizer.zero_grad()
```
## Converting it to 🤗 Accelerate
First the code shown earlier will be converted to utilize 🤗 Accelerate without the special gradient accumulation helper:
```diff
+ from accelerate import Accelerator
+ accelerator = Accelerator()
+ model, optimizer, training_dataloader, scheduler = accelerator.prepare(
+ model, optimizer, training_dataloader, scheduler
+ )
for index, batch in enumerate(training_dataloader):
inputs, targets = batch
- inputs = inputs.to(device)
- targets = targets.to(device)
outputs = model(inputs)
loss = loss_function(outputs, targets)
loss = loss / gradient_accumulation_steps
+ accelerator.backward(loss)
if (index+1) % gradient_accumulation_steps == 0:
optimizer.step()
scheduler.step()
optimizer.zero_grad()
```
<Tip warning={true}>
In its current state, this code is not going to perform gradient accumulation efficiently due to a process called gradient synchronization. Read more about that in the [Concepts tutorial](../concept_guides/gradient_synchronization)!
</Tip>
## Letting 🤗 Accelerate handle gradient accumulation
All that is left now is to let 🤗 Accelerate handle the gradient accumulation for us. To do so you should pass in a `gradient_accumulation_steps` parameter to [`Accelerator`], dictating the number
of steps to perform before each call to `step()` and how to automatically adjust the loss during the call to [`~Accelerator.backward`]:
```diff
from accelerate import Accelerator
- accelerator = Accelerator()
+ accelerator = Accelerator(gradient_accumulation_steps=2)
```
Alternatively, you can pass in a `gradient_accumulation_plugin` parameter to the [`Accelerator`] object's `__init__`, which will allow you to further customize the gradient accumulation behavior.
Read more about that in the [GradientAccumulationPlugin](../package_reference/accelerator#accelerate.utils.GradientAccumulationPlugin) docs.
From here you can use the [`~Accelerator.accumulate`] context manager from inside your training loop to automatically perform the gradient accumulation for you!
You just wrap it around the entire training part of our code:
```diff
- for index, batch in enumerate(training_dataloader):
+ for batch in training_dataloader:
+ with accelerator.accumulate(model):
inputs, targets = batch
outputs = model(inputs)
```
You can remove all the special checks for the step number and the loss adjustment:
```diff
- loss = loss / gradient_accumulation_steps
accelerator.backward(loss)
- if (index+1) % gradient_accumulation_steps == 0:
optimizer.step()
scheduler.step()
optimizer.zero_grad()
```
As you can see the [`Accelerator`] is able to keep track of the batch number you are on and it will automatically know whether to step through the prepared optimizer and how to adjust the loss.
<Tip>
Typically with gradient accumulation, you would need to adjust the number of steps to reflect the change in total batches you are
training on. 🤗 Accelerate automagically does this for you by default. Behind the scenes we instantiate a [`GradientAccumulationPlugin`] configured to do this.
</Tip>
<Tip warning={true}>
The [`state.GradientState`] is sync'd with the active dataloader being iterated upon. As such it assumes naively that when we have reached the end of the dataloader everything will sync and a step will be performed. To disable this, set `sync_with_dataloader` to be `False` in the [`GradientAccumulationPlugin`]:
```{python}
from accelerate import Accelerator
from accelerate.utils import GradientAccumulationPlugin
plugin = GradientAccumulationPlugin(sync_with_dataloader=False)
accelerator = Accelerator(..., gradient_accumulation_plugin=plugin)
```
</Tip>
## The finished code
Below is the finished implementation for performing gradient accumulation with 🤗 Accelerate
```python
from accelerate import Accelerator
accelerator = Accelerator(gradient_accumulation_steps=2)
model, optimizer, training_dataloader, scheduler = accelerator.prepare(
model, optimizer, training_dataloader, scheduler
)
for batch in training_dataloader:
with accelerator.accumulate(model):
inputs, targets = batch
outputs = model(inputs)
loss = loss_function(outputs, targets)
accelerator.backward(loss)
optimizer.step()
scheduler.step()
optimizer.zero_grad()
```
<Tip warning={true}>
It's important that **only one forward/backward** should be done inside the context manager `with accelerator.accumulate(model)`.
</Tip>
To learn more about what magic this wraps around, read the [Gradient Synchronization concept guide](../concept_guides/gradient_synchronization)
## Self-contained example
Here is a self-contained example that you can run to see gradient accumulation in action with 🤗 Accelerate:
```python
import torch
import copy
from accelerate import Accelerator
from accelerate.utils import set_seed
from torch.utils.data import TensorDataset, DataLoader
# seed
set_seed(0)
# define toy inputs and labels
x = torch.tensor([1., 2., 3., 4., 5., 6., 7., 8.])
y = torch.tensor([2., 4., 6., 8., 10., 12., 14., 16.])
gradient_accumulation_steps = 4
batch_size = len(x) // gradient_accumulation_steps
# define dataset and dataloader
dataset = TensorDataset(x, y)
dataloader = DataLoader(dataset, batch_size=batch_size)
# define model, optimizer and loss function
model = torch.zeros((1, 1), requires_grad=True)
model_clone = copy.deepcopy(model)
criterion = torch.nn.MSELoss()
model_optimizer = torch.optim.SGD([model], lr=0.02)
accelerator = Accelerator(gradient_accumulation_steps=gradient_accumulation_steps)
model, model_optimizer, dataloader = accelerator.prepare(model, model_optimizer, dataloader)
model_clone_optimizer = torch.optim.SGD([model_clone], lr=0.02)
print(f"initial model weight is {model.mean().item():.5f}")
print(f"initial model weight is {model_clone.mean().item():.5f}")
for i, (inputs, labels) in enumerate(dataloader):
with accelerator.accumulate(model):
inputs = inputs.view(-1, 1)
print(i, inputs.flatten())
labels = labels.view(-1, 1)
outputs = inputs @ model
loss = criterion(outputs, labels)
accelerator.backward(loss)
model_optimizer.step()
model_optimizer.zero_grad()
loss = criterion(x.view(-1, 1) @ model_clone, y.view(-1, 1))
model_clone_optimizer.zero_grad()
loss.backward()
model_clone_optimizer.step()
print(f"w/ accumulation, the final model weight is {model.mean().item():.5f}")
print(f"w/o accumulation, the final model weight is {model_clone.mean().item():.5f}")
```
```
initial model weight is 0.00000
initial model weight is 0.00000
0 tensor([1., 2.])
1 tensor([3., 4.])
2 tensor([5., 6.])
3 tensor([7., 8.])
w/ accumulation, the final model weight is 2.04000
w/o accumulation, the final model weight is 2.04000

To use this function absolutely zero calls to a CUDA device must be made in the notebook session before calling. If
any have been made, you will need to restart the notebook and make sure no cells use any CUDA capability.
Setting `ACCELERATE_DEBUG_MODE="1"` in your environment will run a test before truly launching to ensure that none
of those calls have been made.

Args:
function (`Callable`):
The training function to execute. If it accepts arguments, the first argument should be the index of the
process run.
args (`Tuple`):
Tuple of arguments to pass to the function (it will receive `*args`).
num_processes (`int`, *optional*):
The number of processes to use for training. Will default to 8 in Colab/Kaggle if a TPU is available, to
the number of GPUs available otherwise.
mixed_precision (`str`, *optional*, defaults to `"no"`):
If `fp16` or `bf16`, will use mixed precision training on multi-GPU.
use_port (`str`, *optional*, defaults to `"29500"`):
The port to use to communicate between processes when launching a multi-GPU training.

# Language Adaptation through Continued Pretraining
This directory shows a base example of how to use continued pretraining and further tuning to adapt a language model to new data (e.g. a new language or domain).
Three steps are needed: continued pretraining (`cpt`), supervised finetuning (`sft`), and direct preference optimisation (`dpo`). In this dummy example we'll continue pretraining gpt2 on Dutch raw data, then sft-tuning it, and finally aligning it with DPO. Note that no extensive hyperparameters were tested in this example and that the output models are bad - it is just to show you how you can use the scripts for LM adaptation. The scripts work on 4x 3090s (24GB VRAM). If you have less powerful hardware you may need to reduce the batch size.
## Continued pretraining
This step will further pretrain the original `gpt2` model on plain Dutch text. Note that the script will by default use the `text` column in the dataset but you can change that by specifying `text_column` in the yaml file or on the command-line.
```shell
ACCELERATE_LOG_LEVEL=info accelerate launch \
--config_file recipes/accelerate_configs/multi_gpu.yaml \
--num_processes 4 \
scripts/run_cpt.py \
recipes/gpt2-nl/cpt/config_full.yaml
```
## Supervised finetuning
As other recipes, such as the famous zephyr-7b-beta recipe, have shown, we can then teach our model how to hold a conversation by finetuning it on chat-formatted data. As a base model we'll make use of the output of the previous step.
```shell
ACCELERATE_LOG_LEVEL=info accelerate launch \
--config_file recipes/accelerate_configs/multi_gpu.yaml \
--num_processes 4 \
scripts/run_sft.py recipes/gpt2-nl/sft/config_full.yaml
```
## Direct preference optimisation
Finally, to align the model better with feedback, we can finetune the SFT output with the DPO algorithm. This should improve the quality of the chat capabilities of the model.
```shell
ACCELERATE_LOG_LEVEL=info accelerate launch \
--config_file recipes/accelerate_configs/multi_gpu.yaml \
--num_processes 4 \
scripts/run_dpo.py recipes/gpt2-nl/dpo/config_full.yaml
```
## Conclusion
With the steps above you can adapt an LM to a new domain, more data, or even a different language. Then, with sft and dpo, you can end up building a powerful chatbot, too! All within just three simple commands. It should be obvious that all of these follow a very similar approach, which makes them suitable to apply in parameterized slurm jobs. The neat part is that you can easily overwrite arguments in the yaml files by specifying the overwriting argument as a command-line argument, so the adaptability is also great.

# Training
Training starts with data. We're going to use the huggingface hub and
start with the Hello world dataset of machine learning, MNIST.
Let's start with downloading `MNIST` from [huggingface](https://huggingface.co/datasets/mnist).
This requires [`hf-hub`](https://github.com/huggingface/hf-hub).
```bash
cargo add hf-hub
```
This is going to be very hands-on for now.
```rust,ignore
{{#include ../../../candle-examples/src/lib.rs:book_training_1}}
```
This uses the standardized `parquet` files from the `refs/convert/parquet` branch on every dataset.
Our handles are now [`parquet::file::serialized_reader::SerializedFileReader`].
We can inspect the content of the files with:
```rust,ignore
{{#include ../../../candle-examples/src/lib.rs:book_training_2}}
```
You should see something like:
```bash
Column id 1, name label, value 6
Column id 0, name image, value {bytes: [137, ....]
Column id 1, name label, value 8
Column id 0, name image, value {bytes: [137, ....]
```
So each row contains 2 columns (image, label) with image being saved as bytes.
Let's put them into a useful struct.

## candle-rwkv
The [RWKV model](https://wiki.rwkv.com/) is a recurrent neural network model
with performance on par with transformer architectures. Several variants are
available, candle implements the v5 and v6 versions and can be used with
Eagle 7B([blog post](https://blog.rwkv.com/p/eagle-7b-soaring-past-transformers)).
```bash
$ cargo run --example rwkv --release -- --prompt "The smallest prime is "
avx: true, neon: false, simd128: false, f16c: true
temp: 0.00 repeat-penalty: 1.10 repeat-last-n: 64
The smallest prime is ϕ(2) = 2.
The smallest composite is ϕ(3) = 3.
The smallest perfect number is ϕ(5) = 5.
The smallest perfect square is ϕ(4) = 4.
The smallest perfect cube is ϕ(6) = 6.

# candle-t5
## Encoder-decoder example:
```bash
$ cargo run --example t5 --release -- --model-id "t5-small" --prompt "translate to German: A beautiful candle." --decode
...
Eine schöne Kerze.
9 tokens generated (2.42 token/s)
```
Variants such as [flan-t5](https://huggingface.co/google/flan-t5-small), [flan-ul2](https://huggingface.co/google/flan-ul2) (with `--revision "refs/pr/25"`), and [Co-EdIT](https://huggingface.co/grammarly/coedit-large) are also supported.
## Translation with [MADLAD-400](https://arxiv.org/abs/2309.04662)
MADLAD-400 is a series of multilingual machine translation T5 models trained on 250 billion tokens covering over 450 languages using publicly available data. These models are competitive with significantly larger models.
```bash
cargo run --example t5 --release -- \
--model-id "jbochi/madlad400-3b-mt" \
--prompt "<2de> How are you, my friend?" \
--decode --temperature 0
...
Wie geht es dir, mein Freund?
```
## Sentence embedding example
```bash
$ cargo run --example t5 --release -- --model-id "t5-small" --prompt "A beautiful candle."
