ModuleNotFoundError: No module named 'langchain_openai.chat_models'; 'langchain_openai' is not a package

I installed h2ogpt locally on Windows following the guide at https://github.com/h2oai/h2ogpt/blob/main/docs/README_WINDOWS.md. Following the docs in https://github.com/h2oai/h2ogpt/blob/main/docs/README_LangChain.md, I was trying to set up a user database by running python src/make_db.py --add_if_exists=True --user_path=userdata (where userdata is a directory I created). It results in the error:

$ python src/make_db.py --add_if_exists=True --user_path=userdata
Fontconfig error: Cannot load default config file: No such file: (null)

ModuleNotFoundError: No module named 'langchain_openai.chat_models'; 'langchain_openai' is not a package

Digging into this, I found that it's caused by the file src/langchain_openai.py which overrides the langchain-openai package visibility. This file should be renamed to something else.
