PyO3 error

[LukasJerabek]

I had to downgrade back to 4.17.3 version because in newer versions I got these errors when running tests with pytest. Is PyO3 some sub dependency?

Hint: make sure your test modules/packages have valid Python names.

Yes, it's used by rpds. Please provide something which reproduces the behavior you're seeing.

[Julian]

Closing but happy to look into this if you can share something which reproduces.

[LukasJerabek]

I am still investigating this little bit deeper, because it seems to be caused by how our tests are run, couldnt reproduce it outside our tests run script yet.

[LukasJerabek]

My suspicion has turned to python-cov package now. In case you are interested, since I am still not sure, which package exactly causes it (python-cov or both jsonschema and cryptography), you can check out the reproducer here pytest-dev/pytest-cov#614

[Julian]

Thanks, will perhaps have a look there.
