### How to use |
|
|
|
```python |
|
# install open assistant model_training module (e.g. run `pip install -e .` in `model/` directory of open-assistant repository) |
|
import model_training.models.reward_model # noqa: F401 (registers reward model for AutoModel loading) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name) |
|
model = AutoModelForSequenceClassification.from_pretrained(model_name) |
|
input_text = "<|prompter|>Hi how are you?<|endoftext|><|assistant|>Hi, I am Open-Assistant a large open-source language model trained by LAION AI. How can I help you today?<|endoftext|>" |
|
inputs = tokenizer(input_text, return_tensors="pt") |
|
score = rm(**inputs).logits[0].cpu().detach() |
|
print(score) |
|
``` |
|
