Inversion step fails using xarray version 2022.11.0 #121

Closed laestrada closed 1 year ago

Recently while testing the IMI on our local cluster I hit this error when running the inversion step of the IMI:

It appears to be an issue with the version I used for xarray. originally, I ran with version xarray 2022.11.0 pyhd8ed1ab_0 conda-forge.

Switching to the following version with conda fixed the issue xarray 0.16.2 pyhd3eb1b0_0. Posting and then closing this issue to keep a record of this.
