Cannot import name 'Enum'

During the aimaas security audit I tried to create a testing environment with a database and 2 docker images as from the READM file.

Executing step 3.ii (create a virtual environment) resulted in an import error:

ImportError: cannot import name 'Enum' from partially initialized module 'enum' (most likely due to a circular import) (/home/paolo/Documents/bsc#1210726_aimaas/aimaas/backend/enum.py)

It seems, from this answer 1, that the problem is having a file named enum.py

Locally I solved renaming enum.py in my_enum.py and changing all "from .enum import" into "from .my_enum import"

(and also "from ..enum" in backend/schemas/entity.py

I can make you a pull request if this naming convention is good...

You could try to create the venv when your CWD is the repo root. You don't need to cd into the backend directory to do that 😉

TBH, I'd prefer to convert the backend directory into a Python package with a meaningful name and a setup.py
