[python #WNC-125958]: OSError MetPy

Greetings!

Apologies, this got lost in our pile of messages. If this is still a problem, 
I'd recommend one of two things:

1) Upgrade away from Python 3.6--that's pretty old at this point and many 
packages are starting to drop support for Python 3.6

2) Run `conda update --all` because it looks like your cartopy and shapely are 
both out of date.

Cheers,

Ryan
