This model uses `ChatML` prompt template: |
|
|
|
``` |
|
<|im_start|>system |
|
{System} |
|
<|im_end|> |
|
<|im_start|>user |
|
{User} |
|
<|im_end|> |
|
<|im_start|>assistant |

# How to use |
|
|
|
You can use this model by using `MaziyarPanahi/Llama-3-70B-Instruct-DPO-v0.2` as the model name in Hugging Face's |
|
transformers library. |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer |
|
from transformers import pipeline |
|
import torch |
|
|
|
model_id = "MaziyarPanahi/Llama-3-70B-Instruct-DPO-v0.2" |
|
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_id, |
|
torch_dtype=torch.bfloat16, |
|
device_map="auto", |
|
trust_remote_code=True, |
|
# attn_implementation="flash_attention_2" |
|
) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained( |
|
model_id, |
|
trust_remote_code=True |
|
) |
|
|
|
streamer = TextStreamer(tokenizer) |
|
|

|
model=model, |
|
tokenizer=tokenizer, |
|
model_kwargs={"torch_dtype": torch.bfloat16}, |
|
streamer=streamer |
|
) |
|
|
|
# Then you can use the pipeline to generate text. |
|
|
|
messages = [ |
|
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"}, |
|
{"role": "user", "content": "Who are you?"}, |
|
] |
|
|
|

|
messages, |
|
tokenize=False, |
|
add_generation_prompt=True |
|
) |
|
|
|
terminators = [ |
|
tokenizer.eos_token_id, |
|
tokenizer.convert_tokens_to_ids("<|im_end|>"), |
|
tokenizer.convert_tokens_to_ids("<|eot_id|>") # safer to have this too |
|
] |
|
|
|
outputs = pipeline( |
