Hello @isaacnewton35 !

Are you deploying on Streamlit Sharing? If that’s the case, it seems from this answer that you are missing the package libgl1-mesa-dev.

Can you try adding a packages.txt file with libgl1-mesa-dev inside to the root of your project, which should force the reinstall of the package :slight_smile: ? (You can find and example here)

If on another Cloud provider, you should consult their doc to see how to install a Unix package and reistall it that way.

Hope it helps!

Have a nice day,
Fanilo
