quicksurvey dependency on pyephem #2

Closed forero closed 7 years ago

forero commented 7 years ago

Quicksurvey has a dependency on pyephem, what are the instructions to use that module on NERSC?

sbailey commented 7 years ago

pyephem is included with the base set of external dependencies installed with desi-conda at NERSC. If you want just those external python dependencies but not any of the desi* packages because you are using your own development copies:

module use /global/common/edison/contrib/desi/modulefiles/
module load desi-conda

If you want to load that plus a full set of desi modules:

module use /global/common/edison/contrib/desi/modulefiles/
module load desimodules

Note: source /project/projectdirs/desi/software/desi_environment.sh is equivalent to that, with the additional benefit of taking care of the difference between edison, cori, and data transfer nodes, though currently we only have the full stack installed on edison.

If you want to replace a desi package with your own development copy, e.g. desisim in your $SCRATCH directory:

#- Load a full set of desi packages and external dependencies
module use /global/common/edison/contrib/desi/modulefiles/
module load desimodules

#- Unload and replace specific ones with your development copy
module unload desisim
export PYTHONPATH=$SCRATCH/desisim/py:$PYTHONPATH
export PATH=$SCRATCH/desisim/bin:$PYTHONPATH

Good. I had module load desi-conda/3.5-20160829, which is clearly and old version that didn't include pyephem.
