I am struggling to create my own dataset

Thank you for your response. I have some brief initial questions.

  1. How can I select the columns of one csv file for input, and one for output? and how could I do that where one input is in a column from one csv file and one output is in the column from a different csv file? I have a hard time understanding the docs.
  2. How can I use pretrained models? I asked a question (linked below) that touches on this: Lesson 2 official topic - #605 by cullenaryArtist
