Installing ROOT using a python virtual environment
Sign in to LENGAU and then ssh into chpclic1
$ module purge
$ module add chpc/BIOMODULES
Adds C++ libraries and other things
Here is how you prepare a new environment with ROOT preinstalled:
$ conda create -n root_env root -c conda-forge
This will make a new environment called root_env, and install ROOT into it. The installation takes about 20 minutes to complete…
When complete you can list all your environments and their paths using:
$ conda info --envs
The full path to the root installation amongst others will appear
Activate the conda ROOT environment:
$ conda activate root_env
Confirm whether the ROOT package has been installed, if successfully installed, it should appear in the list of packages:
$ conda list
Launch ROOT
$ root
For each new ROOT session, in an interactive session simply activate the ROOT conda environment and launch ROOT. Deactivate the environment when done using:
$ conda deactivate
