ModuleNotFoundError: No module named 'altair.vegalite.v4'

Hey all :wave:,

Wanted to hop in and say that @Franky1 is right and there were breaking changes in Altair 5 for Community Cloud.

In the short term, the best solution would be to:
Either: pin altair < 5 or upgrade streamlit to >=1.20.0

In the medium term, we’re building in support for Altair 5. Stay tuned!
