This tutorial shows how to install IMAS (after repository split) using EasyBuild. The installation in this tutorial will be performed on the Gateway cluster but it can be done anywhere.

Install EasyBuild

You should install EasyBuild using Python and venv (virtual environment).

module load itm-python/3.10.13
python3 -m venv venv
module purge
source venv/bin/activate
pip3 install easybuild

You can use a different version of Python. Remember to purge all unnecessary modules that can cause conflicts with new modules created by EasyBuild.
