ImportError: attempted relative import with no known parent package

[Sandro]

Hi,

I'm getting the ImportError from subject specifically when building 
python-plotnine for f36 (Python 3.10.7). The same package builds fine 
for f37 and rawhide (Python 3.11.0).

The module the test is trying to import from is present in tests/, so 
I'm a bit stupefied as to why this fails. I also tried with putting an 
empty __init__.py in tests/. But this fails with an OSError in conftest.py.

Copr build: 
https://copr.fedorainfracloud.org/coprs/gui1ty/neuro-sig/build/4988240/

Cheers,

Yes, importing from .conftest in tests should not be possible.

The same package builds fine for f37 and rawhide (Python 3.11.0).

Maybe pytest somehow made this work? It¨s not just Python 3.11 but also pytest 7.

Do you happen to have the exact OSError with a traceback? Maybe it's not related.

True. I guess this needs to be reported upstream then.

I do:

../../BUILDROOT/python-plotnine-0.10.1-2.fc36.x86_64/usr/lib/python3.10/site-packages/tests/conftest.py:30: 
in <module>
     raise OSError(
E   OSError: The baseline image directory does not exist. This is most 
likely because the test data is not installed. You may need to install 
plotnine from source to get the test data.

This is caused by a test in conftest.py itself:
