Thank you I did setup gmsh incorrectly and after adding to the path variable correctly I now can run the provided training sessions.
The mistake I made was when I set my path variable it did not go from the root directory to the gmsh folder and instead went from the directory I started the singularity shell .
export PATH=$PATH:"path from root to gmsh bin folder"

Have you run make_mesh.py first? See The Readme sections make a new mesh and to go further.

So I tried running make_mesh.py and it outputs this error

AssertionError:
I'm pretty sure that it means that the path at "unrolled" doesn't exist. but I can't tell where in the code that it is supposed to make a file at that path. I did some debugging to find what path unrolled pointing to
unrolled = 'mesh/turek_2d.geo_unrolled'
So the name for the path makes sense, however I don't know why there isn't a file there

Ok. You do need to run this script (without error ^^ ) to generate the mesh and initial fields before you can train or anything else when you perform a new training 'on your own' with a specific configuration.
This error is because you do not use gmsh correctly / it is not set up correctly. See either the readme again, or this issue:
