Create (exact)¶

To create an exact copy of the igwn environment on your system, including all transitive dependencies, use conda env create:

SUBDIR=${CONDA_SUBDIR:-$(conda config --show subdir | awk '{print $2}')}
conda env create --file https://computing.docs.ligo.org/conda/environments/$SUBDIR/igwn.yaml # (1)!

1. The complicated-looking SUBDIR=<...> variable assignment before the conda env call just determines the platform you are using, e.g. linux-64.

Then activate it

conda activate igwn

export CONDA_OVERRIDE_ARCHSPEC="haswell"

setenv CONDA_OVERRIDE_ARCHSPEC "haswell"

set -x CONDA_OVERRIDE_ARCHSPEC="haswell"

Create (simple)¶

To create a version of this environment on your system specifying only the packages constrained by the IGWN Conda Distribution definition, use conda create:

SUBDIR=${CONDA_SUBDIR:-$(conda config --show subdir | awk '{print $2}')}
conda create --name igwn --file https://computing.docs.ligo.org/conda/environments/$SUBDIR/igwn.txt # (1)!

1. The complicated-looking SUBDIR=<...> variable assignment before the conda env call just determines the platform you are using, e.g. linux-64.

Then activate it

conda activate igwn

Pin an environment to this package list¶

To pin a new/existing environment to constrain installed packages to match those found in the `igwn environment, without actually installing any of these packages, use the following steps:

1. Create the environment (if needed):

   conda create -n <myenv> <packages>
   

2. Activate the environment

   conda activate <myenv>
   

3. Download the simple package file and install it as the pinned file for the environment:

   Linux / macOSWindows

   Pin the active environment to the igwn package list.

   SUBDIR=${CONDA_SUBDIR:-$(conda config --show subdir | awk '{print $2}')}
   curl -fsLS https://computing.docs.ligo.org/conda/environments/$SUBDIR/igwn.txt -o ${CONDA_PREFIX}/conda-meta/pinned # (1)!

   Pin the active environment to the igwn package list.
