Openai API not allow temperature=0.0 for llama-2-7b-chat-hf #139
Description
When running the llama-2-7b-chat-hf model with openai api for gsm8k(Mathematical Ability Test), it needs to set temperature=0.0
But I get unexpected error like
lm_eval --model local-chat-completions --model_args model=llama-2-7b-chat-hf,base_url=http://localhost:8000/v1 --task gsm8k

Both LLaMA https://github.com/facebookresearch/llama/issues/687 and Transformers https://github.com/huggingface/transformers/pull/25722 officials suggest to ”set do_sample = False in case temperature = 0“
But openai api’s
client.chat.completions.create(**kwargs)
It does not support the do_sample parameter, and there is no suitable args to solve the problem of temperature=0.0
