This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun. Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good. Okay, let's start OpenCV and Python installation.Step 0: We assume that you have opened
