oh now it’s ok! it’s cooked and out of oven 
i want to cry… i’m back with this now :
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
And the solution here does not work 
Anyway, the initial issue seems to be solved, thanks!
how to use google api instead of requirements.txt
You don’t have to use google api, this is a misunderstanding.
Just fix your requirements.txt file.
Community Cloud has been updated so that protobuf is not pinned to this older version except for old versions of streamlit. So, if you’re using a relatively new version of streamlit, you will no longer see this pinning happen, and will be able to use libraries that depend on newer versions of protobuf (e.g. tensorflow).
