Greetings!

I saw your Stack Overflow post:

  
https://stackoverflow.com/questions/71129263/metpy-import-issue-in-debian-10/71133366

If the answer there didn't help, can you tell me how MetPy was installed? I 
can't find MetPy listed for Debian Buster, and the version 1.0.0rc1.po is 
unofficial, so it's completely unclear what code that actually contains.

Alternatively, installing MetPy 1.0.1 from pip could also work if you uninstall 
python3-metpy and do:

    pip install --no-deps metpy==1.0.1

Cheers!

Ryan
