Openai API not allow temperature=0.0 for llama-2-7b-chat-hf

[yutianchen666]

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

The error is similar when testing temperature=0.0 using llm-on-ray query_openai_sdk.py --model_name llama-2-7b-chat-hf --temperature 0.0

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
