in codespace, the app runs OK, but in streamlit, there is a chroma error (NOK) (config has CHROMA_SERVER = False) #45

*** chroma not as a server ===> that's the case in codespace and in streamlit ===> ok

dodeeric commented 4 weeks ago

streamlit error only: Error: Chroma is running in http-only client mode, and can only be run with 'chromadb.api.fastapi.FastAPI' as the chroma_api_impl. see https://docs.trychroma.com/usage-guide?lang=py#using-the-python-http-only-client for more information.

Error: Is the DB available?

Error: [Errno 2] No such file or directory: './chromadb/chroma.sqlite3'

dodeeric commented 4 weeks ago

in streamlit, usually, after reboot, an empty chroma.sqlite3 file is created (db empty) --> no more???

dodeeric commented 4 weeks ago

What if I delete the chromadb dir in codespace? Will the build of the chroma db still be ok?

Do also a pip install --upgrade -r requirements.txt

===> All OK

dodeeric commented 4 weeks ago

If I switch back to backend_v2, all ok again?

===> Still the same error in Streamlit

What if I fix the version of langchain to the old version? langchain 0.2.1 --> 0.1.20 langchain-community 0.2.1 --> 0.0.38

===> Codelab: ok ===> Streamlit: still nok

dodeeric commented 4 weeks ago

streamlit: python 3.11? no more 3.10.13 as on github codespace?

===> reinstalled the app in streamlit with python 3.10: still the same error

dodeeric commented 4 weeks ago

still the error if:

dodeeric commented 4 weeks ago

quid remove chromadb-client from requirements.txt (not needed)? il faut réinstaller l'app dans streamlit alors (on sais pas faire pip uninstall)

==> it seems it solved the problem: after delete app, reinstall app, there is again an empty sqlite db file.
