Use the packaging [1] module for parsing version numbers, instead of pkg_resources which is distributed with setuptools. I recently switched over to using the latter, knowing it was deprecated (in favor of the packaging module) because it comes with Python out of the box. Newer versions of setuptools have removed `pkg_resources` so we have to use packaging. [1] https://pypi.org/project/packaging/
