survey simulations tutorial fails with AttributeError: 'Configuration' object has no attribute 'tiles_nogray'

[forero]

While testing the survey_simulations notebook in the tutorials with kernel 22.2

https://github.com/desihub/tutorials/blob/ddd19ef4dae83c906d6c11659989f82f55e046ff/survey-simulations.ipynb

the following error arises

---------------------------------------------------------------------------

AttributeError: 'Configuration' object has no attribute 'tiles_nogray'

what would be the correct fix to that?

The issue is that the tutorial is using files from a surveysim run from 2018, and the format has changed somewhat since then. I've put a new run here:
/global/cfs/cdirs/desi/survey/planning/surveysim-tutorial
which may be more likely to work.

Sorry to be dense, but is the recommended way to test this to clone the tutorials repo, load it up in a NERSC juypyter session, and run the commands? I'm not sure I've ever actually used a tutorial before.
