ModuleNotFoundError: No module named 'langchain_community'

[G-Ivan]

Hi, I cloned the repository and tried to run it, I get the error:

Projects/Python/llamaindexchat/.venv/lib/python3.8/site-packages/langchain/chat_models/init.py", line 28, in getattr
from langchain_community import chat_models
ModuleNotFoundError: No module named 'langchain_community'

Is that related to a specific langchain library that must be installed? I have't seen langchain in the requirements file
