Edit existing protobuff and regenerate to Python modules and can't import those modules

[Tam Nguyen]

Hi everyone! I am new to protobuff and need to edit an existing protobuff file to regenerate Python modules of an existing package (as I want to customize some methods). 

The problem is when I reinstall the customized package and run Python code, it throws the error of not finding those Python modules. The proto used is proto3. Does anyone know how to solve this problem?

Thank you in advance!
