Found the solution! Anyways, you have to call:

py -m pip install imutils in your terminal

The logical explanation I found is this: I have 3 versions of pythons on my computer: 2.7, 3.6, 3.7. I have 3.6 because tensorflow doesn't support python 3.7 yet. But if you only call pip install imutils, it only downloads imutils to your python 3.7 site packages, which is not shared across all the python versions and is not the version I use when I do deeplearning. Therefore, to download imutils to python 3.6 (the version I use), use py -m pip install imutils.

There's still many potholes in my conjecture though: for example, py-m pip install sounds like it doesn't specify downloading to 3.6, so why does it download to 3.6? And, for most of the time, I thought I was working on python 3.7, which should had imutils installed, but maybe I was working on 3.6 instead of 3.7.
