It seems the root in singularity environment was built with python 3.6.8 and the python installed is 3.8.10, which causes problem when trying to use PyRoot.
Singularity xenonnt-montecarlo-development.simg:~> python --version
Python 3.8.10
Singularity xenonnt-montecarlo-development.simg:~> root-config --python-version
3.6.8
Not a problem right now, but wondering whether we want to make this automatic (is possible) at one point. I guess the solution can be not that simple, given the ROOT and G4 dependencies.

Currently it is not possible to run GenerateGeant4.py in the container. The error message is:

Is it possible to use a different precompiled ROOT version? I think @DonNabla ran into the same issue when trying to simulate XENONnT backgrounds on OSG. It is possible to use the C executable directly still with:
./nSort -i <path_to_raw_G4> -d XENONnT -s 2 -m 2
(from Maxime, -s 2
flag saves single- and multi-scatter)
