Install Opencv2 For Python 3.5 On Mac
Problems installing opencv on mac with python. Asked 2012-09-19 08:46:41 -0500. Once I install Python, how do I get to a point where I can click on an application on my dock that opens that allows me to code in Python using OpenCV?

How I managed to install OpenCV3 with Python3 bindings on a macOS 3 minute read I am on macOS Sierra 10.12.5 and I am trying to upgrade my OpenCV2 to OpenCV3 as I want to take advantage of the new things in the library due to some Computer Vision work I’m doing. I want to use the Python bindings and ideally have both those for Python2 and for Python3. Currently got OpenCV 2.4.11 with Python2.7 bindings. My Python installation is the one obtained with Homebrew, not the Mac default one so I’m gonna use that for the task. And the task proved to be a rather annoying challenge indeed. This post is just my little way to give back to the community of wonderful people around who write tutorials, guides and share issues when they try to do these things.
I want to hug you all. The post collects all pf the procedure I’ve followed after several failures, multiple attempts, temporary desires to give up. First I uninstall OpenCV to make sure no conflicts arise during the process, you never know and for these things it’s typically better to do a clean installation. I find the always excellent Pyimagesearch has a guide on exactly this process, which means it’s a known painful process that of installing these sorts of things on Macs.
The guide is. So, following guide, I run brew tap homebrew/science brew install opencv3 --with-contrib --with-python3 --HEAD • --with-contrib is meant to install a repository where additional openCV things are, so good to have • --with-python3 is meant to install the bindings for Python3, those for Python2 are automagically installed instead • --HEAD is for pulling the current Github branch rather than the tagged release one As for the --HEAD part, the guide affirms that this is needed “to avoid the QTKit error that plagues macOS Sierra systems with the current tagged OpenCV 3 releases” and points you to. These details explain that this has to do with the QTKIT library and a deprecation problem. Is an Apple thing for media.
Turns out though (see later), that I don’t really have this problem. Anyway, the command above fails with. #if build.with?('python3') && build.with?('python') # # Opencv3 Does not support building both Python 2 and 3 versions # odie 'opencv3: Does not support building both Python 2 and 3 wrappers' #end The Cellar is the place Homebrew installs stuff and then symlinks (or you have to) to where it is actually supposed to be found by Python, see.
