*** Bug 1910392 has been marked as a duplicate of this bug. ***

Spec sanity:

1) Consider using and URL that contains name:

Source0:        %{url}/archive/%{version}/%{pypi_name}-%{version}.tar.gz

It plays much nicer with other tarballs when %_sourcedir is a common location on packager's machine.


2) %{?python_provide:...} is deprecated and SHOULD NOT be used, see https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_the_py_provides_macro 


Other than that, looks sane.

Oh, one more thing.

3) Please move %generate_buildrequires after %prep, when it happens. It makes the reader flow follow to the execution flow.

I've got a test failures when building via mock:

+ /usr/bin/pytest --ignore /builddir/build/BUILD/build-0.5.1/.pyproject-builddir -k 'not test_build_package and not test_build_package_via_sdist'

I was checking what happened that your copr build passed and my mock build did not. Apparently, I had some extra packages installed in mock from the jupyter-packaging revew, Fedora-Review did not clean that mock and it made the build fail like this :( Weird as it is, it passed now when I cleaned my mock, sorry for the noise.
