"setup_expt.py" failed on Orion because of module named 'yaml'

[wzzheng90]

Hi,

I tried to run experiment generator script "./setup_expt.py" on Orion and got the following errors.
It looks like about the module named 'yaml'. However, I do not find 'yaml' but 'yafyaml/0.5.1' is available.
After I loaded 'yafyaml/0.5.1', I got the same errors.
What else should I set up on Orion before running "setup_expt.py"?

Did you source workflow/gw_setup.sh?

[wzzheng90]

Thanks, Walter. It works after I type this command!

[wzzheng90]

@WalterKolczynski-NOAA Why I can not use this command (source workflow/gw_setup.sh) on Hera? The error shows "Illegal variable name". Thanks.

[WalterKolczynski-NOAA]

Works for me. Are you maybe not using bash on Hera?

[wzzheng90]

I see. I did use csh on Hera.
Now I use bash and it works. Thanks!!

user reports success after switching to bash.
