    ## Update the compiler

    ## Needed for G4:
    yum -y install xerces-c xerces-c-devel

    ## Needed to make X11 work properly for edep-disp
    yum -y install mesa-dri-drivers

    ## Needed to run the ROOT --> h5 script
    python3 -m pip install numpy
    python3 -m pip install fire
    python3 -m pip install h5py
