Stages requiring the LSST environment

Some ingestion stages may need the LSST environment.

1. Start the LSST env using python /global/common/software/lsst/common/miniconda/start-kernel-cli.py desc-stack (or any new instructions from https://confluence.slac.stanford.edu/display/LSSTDESC/Setting+Up+the+DM+Stack+at+NERSC)

2. Create and start a virtual env based on this (first time only):

   python -m venv --system-site-packages lsst-env
   . lsst-env/bin/activate
   

3. Install ceci in that venv:

   pip install git+https://github.com/LSSTDESC/ceci
   

Then you’re ready.
