Hi, all. I don't understand why the unit test failed. Is this due to an error in baroclinic_example.ipynb? Or is it some other script? I was able to get the notebook to run OK when testing in the container on an M1 MacBook Pro.

Not your fault here, some pip related details are tripping the CI. @fmalatino and @romanc are on it, we will clean up PRs when things stabilizes

Frank merged #117 yesterday. Have you tried updating/rebasing your branch after that?

Something is off with Github CI, it's not the latest that's being pulled. Will solve offline.

The branch being tested is still behind 117 by one commit, updating it should resolve the issue.

I think if you merge the latest version of NOAA-GFDL:develop into this branch it will be all set to merge
