Failure on jupyter at nersc trying to run redrock on desisim outputs #567

Closed forero closed 2 years ago

forero commented 2 years ago

I am trying to update this notebook to make it work under kernel 22.2: https://github.com/desihub/tutorials/blob/52d61df9d4baa603863ff73399d6525e68c820fc/simulating-desi-spectra.ipynb

That notebook generates a series of QSO spectra and then tries to run redrock on them:

rrdesi -i /global/cscratch1/sd/forero/desi/simspec/qso-observed-spectra.fits -o /global/cscratch1/sd/forero/desi/simspec/qso-zbest.fits

That command gives me the following error

Proc 0: KeyError: "Extension 'SCORES' not found."

I am guessing that this is a problem with the desisim output, but I am not sure. Any idea on what could be the problem? The notebook linked above has the full error message.

Unfortunately the 22.2 software release has an incompatibility between simulated QSOs and redrock. See #565 and desihub/redrock#205. If someone can fix this in the next few days, we could include them in a new tag and have the tutorial use the new tag instead of the 22.2 kernel.

It would be especially useful if someone contributes a test in desisim that confirms that the simulated output can be processed by redrock to avoid this kind of problem in the future.

Thanks, @sbailey !
