casegen error on Hera

[juliasimonson-noaa]

I'm trying to generate a driver file on Hera using one of the casegen scripts (UFS_forcing_ensemble_generator.py), but when I ran the script I get the following error:

Traceback (most recent call last):
File "./UFS_forcing_ensemble_generator.py", line 8, in ‹module>
from netCDF4 import Dataset
File "/scratch1/NCEPDEV/nems/role.epic/spack-stack/spack-stack-1.6.0/envs/unified-env-rocky8/install/intel/2021.5.0/py-netcdf4-1.5.8-qs672u4/lib/python3.10/site-packages/netCDF4/init-py" , line 3, in ‹module>
from •_netCDF4 import *
ModuleNotFoundError: No module named 'netCDF4._netCDF4'

Prior to running the script, I had used Hera_intel.lua to load the necessary modules and had activated the conda environment env_ufscasegen.

@juliasimonson-noaa Sorry you having this issue (Moving this to the CCPP SCM repo where the experts can chime in).
Interestingly, I just noticed that my python environments are no longer working with the SCM, with the same netCDF4 error, so I wonder if something is going on with conda/anaconda on Hera?
@hertneky @mkavulich @scrasmussen Have you run into any issues on Hera with the SCM in the past day or so?

@juliasimonson-noaa I think there is a problem with the modules being loaded by the SCM. Can you try removing lines 12-14 from ccpp-scm/scm/etc/modules/hera_intel.lua , and then load the environment (>ml hera_intel), and rerun?

[juliasimonson-noaa]

@dustinswales I removed the lines and loading the environment, was able to avoid the netCDF4 error but still had issues running the SCM. But those issues might be due to something else, I was able to get it to work by running the casegen script in one terminal and running the SCM with hera_intel loaded in another terminal.

@juliasimonson-noaa Good to hear. We are working on a fix for the environment conflict.
