Unresolved reference issue in PyCharm

Manually adding it as you have done is indeed one way of doing this, but there is a simpler method, and that is by simply telling pycharm that you want to add the src folder as a source root, and then adding the sources root to your python path.

This way, you don’t have to hard code things into your interpreter’s settings:

• Add src as a source content root:

• Then make sure to add add sources to your PYTHONPATH under:Preferences ~ Build, Execution, Deployment ~ Console ~ Python Console

After all this don’t forget to restart. In PyCharm menu select: File –> Invalidate Caches / Restart
