Someone knows what it could be?

This warning happens because pytest could not remove the temporary directory created by tmpdir/tmp_path after the tests ended. This is usually caused by one or more tests holding access to files/directories inside those directories.

[kloczek]

So it could be some kind of test unit or some of the pytast extencion issue?🤔

[nicoddemus]

Yes, it is a bit hard to nail down.
