AI foot tracking model

I am a student doing a graduation project. I urgently need to deal with this model (I am attaching a link). I've never worked with python and AI. Please help me understand how to run this model. I really need. Thank you

This is my first time dealing with this. I sat there for a very long time trying to figure it out, but nothing came of it
