	from pkg_resources import parse_version
	assert parse_version(setuptools.__version__)>=parse_version('36.2')

This is a friendly reminder, to tackle this in the future.

Use of pkg_resources is deprecated in favor of importlib.resources, importlib.metadata and their backports (importlib_resources, importlib_metadata). Some useful APIs are also provided by packaging (e.g. requirements and version parsing). Users should refrain from new usage of pkg_resources and should work to port to importlib-based solutions.
