CALDP-2024.10.2-2+enchilada-py311-macos-x86_64

Conda is required to manage installation of the delivery environment. A fresh installation of Miniforge3 is not required for each CALDP delivery, however. An existing conda installation may be used. The method described here allows for multiple entirely separate pipeline installations.

A POSIX-compatible shell (e.g. bash) is required for all steps below. Python dependencies are taken directly from PyPI or development repositories as needed, so conda's ability to install hybrid conda/pip environments from a YAML specification is used. This requires first downloading the specification file and then creating the environment with it.

Installing Conda

If conda is not available on the target system, it will need to be installed and configured before the delivery environment can be installed.

For detailed instructions of this step, please visit: https://conda.io/projects/conda/en/latest/user-guide/install/index.html

Miniforge3:

wget https://github.com/conda-forge/miniforge/releases/download/24.9.0-0/Miniforge3-24.9.0-0-MacOSX-x86_64.sh
bash Miniforge3-24.9.0-0-MacOSX-x86_64.sh
$HOME/Miniforge3/condabin/conda init

Installing CALDP

Option 1: Install this delivery

conda env create \
    --file https://ssb.stsci.edu/stasis/releases/hst/CALDP-2024.10.2+enchilada/delivery/CALDP-2024.10.2-2+enchilada-py311-macos-x86_64.yml

Activate this delivery

conda activate CALDP-2024.10.2-2+enchilada-py311-macos-x86_64

Option 2: Install the latest delivery

Warning: The latest URL may provide software different than what is presented by the release notes section below!

conda env create \
    --name CALDP-latest-py311 \
    --file https://ssb.stsci.edu/stasis/releases/hst/CALDP-2024.10.2+enchilada/delivery/latest-py311-macos-x86_64.yml

Activate the latest delivery

conda activate CALDP-latest-py311

Each new delivery iteration will need to be installed using one of the above commands.
