I tried to install OpenCV, and I couldn't find any suitable pip packages for it. I decided to look online for official documentation on how to install it, and found this. Unfortunately, not only does this documentation only give support for versions using python 2.7, it also says to install OpenCV manually by downloading it from sourceforge rather than using a package manager like pip.
I want to know if there's a better or more official way of installing OpenCV in python 3.5, or failing that, a package in pip I should install instead.
