## Usage
|
41 |
-
To use this model, you can load it with the following code:
|
42 |
-
|
43 |
-
```python
|
44 |
-
from transformers import AutoModel, AutoTokenizer
|
45 |
-
|
46 |
-
model_name = "sh1gechan/flan-t5-large"
|
47 |
-
model = AutoModel.from_pretrained(model_name)
|
48 |
-
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
49 |
-
|
50 |
-
# Example usage
|
51 |
-
inputs = tokenizer("Translate the following sentence to French: 'Hello, how are you?'", return_tensors="pt")
|
52 |
-
outputs = model.generate(**inputs)
|
53 |
-
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
|
54 |
-
```
|
55 |
-
|
56 |
-
## Limitations
|
57 |
-
While the model performs well on a variety of tasks, it has some limitations:
|
58 |
-
- It may not perform as well on highly specialized or domain-specific tasks without further fine-tuning.
|
59 |
-
- The model's responses are only as good as the quality and diversity of the training data.
