IGWN Conda Distribution

MIT license Build status

The IGWN Conda Distribution (IGWN-Conda) is a programme to manage and distribute software and environments used by the International Gravitational-Wave Observatory Network (IGWN) using the conda package manager, the conda-forge community, and the CernVM File System (CVMFS).


Use a pre-built environment (linux only):

CVMFS is read-only

The pre-built environments are read only. If you need a modifiable environment, please see Clone an environment, or Managing packages.

  1. Install and configure CVMFS; if you are running on the IGWN Computing Grid, you will not need to do this.

  2. Configure conda:

    source /cvmfs/
  3. Activate an environment:

    conda activate igwn-py38

Or install miniconda yourself:

  1. Install Miniconda.

  2. Add the conda-forge channel:

    conda config --add channels conda-forge
  3. Download one of the environment YAML files, see Environments.

  4. Install the environment locally:

    conda env create --file <environment>.yaml


For full details of what environments are included in the distribution, and their contents, see Environments.
