Find below some example scripts on how to use the model in `transformers`:

## Using the Pytorch model

### Running the model on a CPU

<details>
<summary> Click to expand </summary>

```python

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("AlexWortega/Flan_base_translated")
model = T5ForConditionalGeneration.from_pretrained("AlexWortega/Flan_base_translated")

input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```

</details>

### Running the model on a GPU

<summary> Click to expand </summary>

```python
# pip install accelerate
from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("AlexWortega/Flan_base_translated")
model = T5ForConditionalGeneration.from_pretrained("AlexWortega/Flan_base_translated", device_map="auto")

input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("AlexWortega/Flan_base_translated")
model = T5ForConditionalGeneration.from_pretrained("AlexWortega/Flan_base_translated", device_map="auto", torch_dtype=torch.float16)

input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("AlexWortega/Flan_base_translated")
model = T5ForConditionalGeneration.from_pretrained("AlexWortega/Flan_base_translated", device_map="auto", load_in_8bit=True)

input_text = "translate English to German: How old are you?"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))

# Uses

## Direct Use and Downstream Use

The authors write in [the original paper's model card](https://arxiv.org/pdf/2210.11416.pdf) that: 

> The primary use is research on language models, including: research on zero-shot NLP tasks and in-context few-shot learning NLP tasks, such as reasoning, and question answering; advancing fairness and safety research, and understanding limitations of current large language models

See the [research paper](https://arxiv.org/pdf/2210.11416.pdf) for further details.

## Out-of-Scope Use

# Bias, Risks, and Limitations

The information below in this section are copied from the model's [official model card](https://arxiv.org/pdf/2210.11416.pdf):

> Language models, including Flan-T5, can potentially be used for language generation in a harmful way, according to Rae et al. (2021). Flan-T5 should not be used directly in any application, without a prior assessment of safety and fairness concerns specific to the application.

## Ethical considerations and risks

> Flan-T5 is fine-tuned on a large corpus of text data that was not filtered for explicit content or assessed for existing biases. As a result the model itself is potentially vulnerable to generating equivalently inappropriate content or replicating inherent biases in the underlying data.

## Known Limitations

> Flan-T5 has not been tested in real world applications.

## Sensitive Use:

> Flan-T5 should not be applied for any unacceptable use cases, e.g., generation of abusive speech.
