I'm using PyCharm and I'm importing some constants from another python file in the same directory. The import works at runtime, but I get this annoying red underline on the import statement and also every time I use a constant from the file.
Here's the file hierarchy
(Please ignore the red underlining on the folders, they are unrelated to this)
What causes this behaviour and how can I fix it?
It is better if you replace that with:
from pca_mixtures.constants import *
The issue is because of how PyCharm sets PYTHONPATH to the root of your project.
While you can add directories as Sources, I would not recommended. That will make your project fragile.
You can right click pca_mixtures and then mark the directory as Sources Root, this should solve your problem. Good luck!
You can use from .constants import *.
Always check if you're able to control+click/ cmd+click to your imported file
