Cannot find reference 'init_palm_chat' in 'api_provider.py'

[qaswzh]

from fastchat.serve.api_provider import init_palm_chat

The code above has a problem "Cannot find reference 'init_palm_chat' in 'api_provider.py' "
I can't find anything about init_palm_chat from the file "api_provider ".

How to fix this?
Thank you!
