ESMF and ESMpy versions incompatible?

[hdrake]

When I try to

import momgrid

within the /nbhome/jpk/envs/py311 environment, I get the following error about inconsistent packages.

Because of this, I currently cannot run my MAR notebook for bottom properties. I developed the notebook in a separate environment where I locally installed momgrid and momlevel myself with pip.

I was not able to replicate this error on my end, @hdrake . Is it possible you have a conflict in your user / local environment? Check $HOME/.local/python3.11 ....

[hdrake]

That's possible, but I thought that the whole point of using a conda environment was that it protects against this?

[jkrasting]

That was what I had hoped. There would need to be a way to disable the local search paths (if this is indeed the issue). Let's connect on slack.
