Incorrect `root_dir`

[AlexGKim]

The default path for root_dir causes an error

With the default

GCRCatalogs.get_root_dir()
'/global/cfs/cdirs/lsst/shared/xgal/skysim/'

I get the error

ValueError: Catalog directory /global/cfs/cdirs/lsst/shared/xgal/skysim/xgal/skysim/skysim_v3.1.0 does not exist

Whereas to make things work I had to set the path to

GCRCatalogs.set_root_dir('/global/cfs/cdirs/lsst/shared/')

@AlexGKim Thanks. But I wasn't able to reproduce the error. I got the correct root_dir path when importing GCRCatalogs v1.6.0. Did you run anything else before calling GCRCatalogs?

In [4]: import GCRCatalogs

In [5]: GCRCatalogs.get_root_dir()
Out[5]: '/global/cfs/cdirs/lsst/shared'

In [6]: GCRCatalogs.__version__
Out[6]: '1.6.0'

[AlexGKim]

The problem is that I ran the command

python -m GCRCatalogs.user_config set root_dir /path/to/the/download/directory

Do you know how I can undo this without rerunning the above command, which I can't run again due to silly reasons?

[yymao]

Can you run

python -m GCRCatalogs.user_config del root_dir

?

If not, can you go to ~/.config/lsstdesc/ and remove the user config file directly?

[AlexGKim]

Success! I fixed the config file.
