How to activate the DESC software environmentΒΆ

The software environment developed and maintained by members of the LSST Dark Energy Science Collaboration (DESC) is installed under

/pbs/throng/lsst/software/desc

You can activate the DESC environment with the command

source /pbs/throng/lsst/software/desc/common/miniconda/setup_current_python.sh

This command initializes or extends some environment variables (e.g. PATH, PYTHONPATH, etc.) and activates a DESC-specific conda environment.

If you need to use the DESC software environment from within your Jupyter notebooks, please refer to How to execute LSST-enabled JupyterLab notebooks.

Warning

Under some circumstances, activating the DESC software environment in a session where you have activated the LSST science pipelines may not work. If you observe unexpected behavior, try activating each of those environments in different shell sessions.
