Other Python Libraries/Modules

Has anybody had success with other/alternative libraries and modules python offers such as PIL (pillow), NumPy, etcetera? I understand some options aren’t fully available because a lot is updated for python 3, but this question hasn’t been posed for a while in this forum and I’m curious as to whether anybody has had success in the meantime. I’m excited to be at a point where I’ve found the limitations of the ETC processor for my own purposes. Share anything you’ve created!
