Can't get NeuralPDE Example code to run

Hi folks!
I’m trying to get the example code for the NeuralPDE package up and running, but copy/pasting it returns the following:

ERROR: DivideError: integer division error

Does anyone know what I’m doing wrong, or what packages I need to include?

Thank you!
