Issues in running app.py

[spsach]

It seems like there are many modules that probable have not been installed through requirements.txt but are still being imported. I have seen 4 so far:
Line 7: ModuleNotFoundError: No module named 'networks'
Line 26: ModuleNotFoundError: No module named 'openai'
Line 28: ModuleNotFoundError: No module named 'pyarrow'
Line 36: ModuleNotFoundError: No module named 'graphrag.query'

It will help if we can either clarify in the documentation that we need to comment out certain statements in app.py or update the requiremnets.txt

Thanks a lot
