Hi Carles, Thanks for your thoughts! Yes, indeed that seems to be the issue. But what I don't understand is why the import is turned into .pybuild.cpython3_3.9_qtpy.build.qtpy.tests and not just qtpy.tests or a longer path, and why only this package fails in this way. Perhaps this is the only package that has an import statement in pytest_configure?
