There is a known issue on Community Cloud where pinning Streamlit to version 1.19 or lower will cause some packages to be reinstalled after your requirements file is resolved. This can cause undesirable upgrades in some packages (namely, all of altair’s dependencies). If you are able to increase your Streamlit version to at least 1.20, you can avoid this issue prior and respect the remainder of your pins.

Problem deploying my app on streamlit

I have reported the issue and it’s being tracked, but I don’t have an ETA on when it will be addressed for sure. I was able to further refine my understanding though: this bug is triggered if your requirements file results in streamlit <=1.19. So you should be able to pin as far back as 1.20 without triggering the bug. What happens when Community Cloud detects Streamlit is version 1.19 or lower is that altair<5 gets installed afterwards, all by itself. So it’s altair’s dependencies in particula…
