Hi Ken,
Well, I’m not exactly sure how Fedora 35 can ship with Matplotlib 3.5.0
considering it hasn’t been released yet (3.5.0rc1 is the latest and is a
pre-release):
https://github.com/matplotlib/matplotlib/releases
At any rate, this is a known incompatibility between MetPy and the next
release of Matplotlib, and will be fixed in the next version of MetPy
(1.2.0), scheduled to be released in a few weeks. You can track progress on
fixing that specific issue here:
https://github.com/Unidata/MetPy/pull/2179
Hope this helps,
Ryan
