Question about the CESM2 case set-up?

[mengqi]

Hi,

I am working with CESM2, but I’m currently unable to set up a case using the prompt below (bold). It’s strange because this prompt worked previously. Could anyone provide some input or suggestions? Thanks!

Traceback (most recent call last):

Are you trying to run this from within a conda environment, i.e., (npl)?

Thank you, Oleson! Yes, it did work before.

So, "imp" is an old python library that was removed in Python 3.12 or so. It looks like your current environment has a newer python version than the code you are trying to run is expecting. You should change your conda environment to one that includes python 3.5 or so, I think.
