Where following functions come from?

  1. pprint_train()
  2. print_pred_movies()
  3. print_existing_user()
  4. gen_user_vecs()
  5. predict_uservec()
  6. get_user_vecs()

I do not think these are common functions from some common package such as numpy, sklearn, but cannot find the definition in the code. How do they introduced or implemented?

Kind Regards,

There can be some supporting .py files coming with each lab, and you probably had seen some of those files’ names in the lab’s import lines. You can find those files by going to your coursera notebook, then in the notebook’s menu bar, click “File” > “Open”.
