Hello, the code you provided cannot run, what is the reason?

[CUITCHENSIYU]

When the model.py file is running, there will be two problems: "ModuleNotFoundError: No module named'st_remux'", and this package cannot be found. Where does this package come from? The second question: the "get_ipython()" function also did not find the defined location. I hope you can solve my difficulties, thank you!
