Invalid no-name-in-module from pylint on scikit-image>=0.19.0 using filters module about scikit-image

[lagru]

Thanks for the report @defe007. I can reproduce this, however, I'm not sure that this is an error on scikit-image's side. I can reproduce this without scikit-image being involved with the following minimal example:

# lib/__init__.py

import lazy_loader as lazy
__getattr__, __dir__, __all__ = lazy.attach_stub(__name__, __file__)

# lib/__init__.pyi
__all__ == ["bar"]
from ._foo import bar

# lib/_foo.py
def bar():
    print("I'm happy")

from lib import bar
bar()

Create a virtual environment with lazy_loader and pylint and inside the directory containing lib run

python test.py  # works and prints "I'm happy"
pylint test.py  # fails with 
# test.py:1:0: E0611: No name 'bar' in module 'lib' (no-name-in-module)

As this the code in question is working as intended, I'm guessing that pylint isn't recognizing the PYI file or giving it's content priority over __init__.py. So I'd probably inquire with Pylint first and lazy_loader second if this is a bug on their side.

Therefore, I'm closing this for now. But feel very welcome to add something here if you don't agree or have something to add. :)

No of course not. ;) Also tagging @jarrodmillman because of lazy_loader.

Thank you @lagru for your insight. I've opened an issue with pylint. I hope you don't mind me using your example.
