maybe the best solutin is to fix the version number of matplotlib. I do not know if it is allow to provide a version number  with the a debian version in it...

The best would be to use the packaging.version Version type in order to deal with these verrsion comparisons.

from packaging.version import Version

v = Version(matplotlib.__version__)
v < Version ("3.3.3")

Good idea. I see you have just forwarded the bug upstream. Thanks a lot.
