module 'MatterSim' has no attribute 'Simulator'

[carzh]

Hello! I followed the instructions from the Docker set-up. When attempting to run the simulator on another dataset, I got the error "No module named MatterSim." I followed the instructions from #16 to try to resolve this issue, and instead got the following error: " sim = MatterSim.Simulator()
AttributeError: module 'MatterSim' has no attribute 'Simulator'
"
which I've been unable to resolve. I am also managing Python dependencies using a virtual environment. Any tips would be super appreciated!
