Snippet: 
Error: The version in the Python package metadata 0.0.0 normalizes to zero.
It's likely a packaging error caused by missing version information
(e.g. when using a version control system snapshot as a source).
Try providing the version information manually when building the Python package,
for example by setting the SETUPTOOLS_SCM_PRETEND_VERSION environment variable if the package uses setuptools_scm.
If you are confident that the version of the Python package is intentionally zero,
you may %define the _python_dist_allow_version_zero macro in the spec file to disable this check.

error: Dependency tokens must begin with alpha-numeric, '_' or '/': *** PYTHON_PROVIDED_VERSION_NORMALIZES_TO_ZERO___SEE_STDERR ***
This snippet explains that package metadata version is normalized to zero. This is undesired, since package has a non-zero actual version (0.5.6-1.fc43). There is likely a definition error in the package.
