Streamlit APP worked before and now crash -- import tensorflow

Thank you for your answer,

I don’t even know what is protobuf package and I don’t use it

So I addeed in the requirement file :
protobuf==3.9.2
but it doesn’t work, same message saying that I have to downgrade to <3.20 (which 3.9.2 is…)
I saw this post :

Streamlit run with protobuf error

I encountered the same problem and avoided it by installing the compatible version of protobuf: pip install 'protobuf~=3.19.0' To deploy it on Streamlit Cloud, I added a line to requirements.txt: For core dev team: This is because the version of protobuf as a dependency of the streamlit package is specified as protobuf = ">=3.6.0, !=3.11", which allows installing major version-ups that may have breaking changes. And it actually led to install a new version 4.21.0, which was released…

So I tried protobuf~=3.19.0
But same message, it seems that it doesn’t want to install this version…
This is so annoying to have to go back to working API and past severa hours to understand why it doesn’t work…
