-
|
| 40 |
-
```python
|
| 41 |
-
from transformers import AutoModelForCausalLM, AutoTokenizer
|
| 42 |
-
|
| 43 |
-
model_name = "learning-unit/L1"
|
| 44 |
-
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
|
| 45 |
-
model = AutoModelForCausalLM.from_pretrained(
|
| 46 |
-
model_name,
|
| 47 |
-
torch_dtype="auto",
|
| 48 |
-
device_map="auto",
|
| 49 |
-
trust_remote_code=True,
|
| 50 |
-
)
|
| 51 |
-
|
| 52 |
-
messages = [
|
| 53 |
-
{"role": "user", "content": "What are the diagnostic criteria for sepsis?"}
|
| 54 |
-
]
|
| 55 |
-
inputs = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
|
| 56 |
-
inputs = inputs.to(model.device)
|
| 57 |
-
outputs = model.generate(inputs, max_new_tokens=512)
|
| 58 |
-
print(tokenizer.decode(outputs[0][inputs.shape[-1]:], skip_special_tokens=True))
|
| 59 |
