I am trying to use Python 3.6.5_1 for OpenCV, so I have switched Python versions using "brew switch python 3.6.5_1", but after checking my current version of Python using "python --version", I apparently am still using Python version 3.7.2. Any solutions? By the way, this is the tutorial I am following: https://www.pyimagesearch.com/2018/08/17/install-opencv-4-on-macos/

Check your python path to see where your python executable is being stored---which python in terminal. I bet it's still pointing to your 3.7.2 directory's python.
If you are switching between python versions, virtualenv can be used to initialize isolated environment with a specific python version.
virtualenv -p [preferred-python-version] open_cv_project_env
