Hello @taha_fawzy_anwar,

It is jumping too fast to ask whether you need something before you know what those something are.

I suggest you to take one step at a time, by first knowing what each of those variables and files do.

Here are the steps:

  1. Go through the whole notebook once to get an overall understanding.
  2. To focus on, for example, what item_train does, use your browser’s search function to find and study all occurences of it. Also, you might print and inspect its content.
  3. Repeat step 2 for each of those variables that you are confused with.
  4. For the files, they are read and stored in variables too, so inspect those variables with step 2 as well.

After you know what they do, you determine whether they are needed for your project. We can’t determine it for you because it is your project.

Cheers,
Raymond
