Wiki ▸ Documentation ▸ Installing Previous CDAT Versions

Installing from environment file

The easiest way to install earlier official stable releases of CDAT is to download the corresponding conda environment using the provided links below.

For older CDAT versions, we provide env files for both Mac and Linux and for Python2 and Python3.

For each of these we also provide a mesalib-enabled version which is especially useful for users running batch jobs remotely on "headless" machines that do not have a graphics card or display attached. In the mesalib-enabled version plot will NOT require a X11 connection and images will be rendered in memory rather than onscreen. A user will not see any results until he or she saves the output to a .png file.

Once downloaded simply run:

conda env create -n [your_env] -f [your_env].yaml

conda activate [your_env]

On older conda versions you might need:

source activate [your_env]

Installing previous versions from conda channels

Alternatively, you can use regular conda commands to generate the environment.

Steps below will install CDAT 8.1

For Python 3, use:

conda create -n [your_env] -c cdat/label/v81 -c conda-forge python=3.6 cdat

conda activate [your_env]

For Python 2, use:

conda create -n [your_env] -c cdat/label/v81 -c conda-forge python=2.7 cdat

conda activate [your_env]

On older versions of anaconda you might need:

source activate [your_env]

If you wish to obtain the mesalib-enabled version (headless display) simply add mesalib at the end of the install line:

conda create -n [your_env] -c cdat/label/v81 -c conda-forge python=3.6 cdat mesalib

For Python 2 use:

conda create -n [your_env] -c cdat/label/v81 -c conda-forge python=2.7 cdat mesalib

or simply install it after the fact.

conda install -c cdat/label/v81 -c conda-forge mesalib vtk-cdat
