Problem when trying to import a python module

I'm trying to create a python project for automated acceptance testing. I read a lot about the patterns I could use and I got to the current structure.

I can't understand where I'm going wrong. I've already reviewed where the import error is pointed out, but I can't understand where the error is.

Traceback (most recent call last):

    from core.BaseTest import BaseTest
