[MITgcm-support] rdmds & error

[Mahdi Mohammadi]

Hi,
 After several years I am updating my scripts using MITgcmutils. Unfortunately, I receive the following errors. I am unsure if these errors are relevant to my grids files, my python3, or ...
I would be grateful if anybody could advise me.
Best, Mahdi
