module '__main__' has no attribute '__spec__'

Describe the bug

While enabling the use of multiprocessing for the computation of GDPs, I have hit a bug so hard that it led me to submit my first StackOverflow question.

The following work-around has been implemented in the code for now:

        import sys
        try:
            sys.modules['__main__'].__spec__ is None
        except:
            logger.warning('BUG: __spec__ is not set. Fixing it by hand ...')
            sys.modules['__main__'].__spec__ = None

This ticket is to remember to fix this. And beg for help. 😢

To Reproduce
See the MWE on my StackOverflow question.
