  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'einsteinpy.testing'

🎯 Goal

I'm trying to make the notebooks more interactive with ipywidgets so that it is more clear what is going on and how the output changes with a change in variable. Other people will be able to use these to learn these abstract topics
