Import Error

[dr9216]

Hi, I'm trying to run your code I obtain this error:

ImportError: cannot import name 'StreamlitChatMessageHistory' from 'langchain.memory.chat_message_histories' (C:\Users\ASUS\AppData\Local\Programs\Python\Python310\lib\site-packages\langchain\memory\chat_message_histories_init_.py)

Traceback:
File "C:\Users\ASUS\AppData\Local\Programs\Python\Python310\lib\site-packages\streamlit\runtime\scriptrunner\script_runner.py", line 535, in _run_script
exec(code, module.dict)
File "C:\Users\ASUS\Desktop\2024-02-13_chat-with-a-website-main\chat.py", line 10, in
from langchain.memory.chat_message_histories import StreamlitChatMessageHistory

How can I fix this?

This issue is likely due to the lower version of the langchain used while the code would have been written, try pinning it with langchain==0.0.330 and issue should be resolved.
