How to Install OpenCV 3.0 and Python 2.7+ on OSX This tutorial still works perfectly if you are using OSX Yosemite or prior, but if you want to install OpenCV on the newer El Capitan and macOS Sierra please use this freshly updated tutorial. UPDATE: The tutorial you are reading now covers how to install OpenCV 3.0 with Python 2.7 bindings on OSX Yosemite and below. But for now, let’s stick with what we know and use Python 2.7. If you’re an Ubuntu or Raspberry Pi user, be sure to keep an eye on PyImageSearch as I’ll be posting OpenCV 3.0 install instructions for Ubuntu and the Raspberry Pi as well.Ī quick note before we get started: While OpenCV 3.0 is indeed compatible with Python 3+, most computer vision developers are still using Python 2.7 (since OpenCV 2.4.X is only compatible with Python 2.7). If you’re a Python 3 user and excited to give the bindings a try - don’t worry! I’ll be covering OpenCV 3.0 and Python 3+ installation in a future tutorial. We’ll Go ahead and kick-off our OpenCV 3.0 install fest by installing v3.0 with Python 2.7+bindings on the OSX platform. With OpenCV 3.0 it doesn’t get any easier - and there are definitely some caveats and gotchas that you need to look out for (such as the opencv_contrib repository - without it, you’ll be missing out on some important features, such as SIFT, SURF, etc.)īut don’t worry, I’ve got you covered! Just keep following along with the PyImageSearch blog and I promise these tutorials will get you up and running with OpenCV 3.0 in no time. In most cases you’ll be pulling down the repo, installing prerequisites, compiling by hand, and hoping that your installation goes smoothly. It’s not like you can let pip or easy_install to the heavy-lifting for you. We’ll also be performing these Python 2.7 and Python 3+ installations on a variety of platforms including OSX, Ubuntu, and yes, the Raspberry Pi.Īs I’m sure you already know, OpenCV has never been an effortless library to install.

To celebrate opencv 3.0, I have decided to perform a series of blog posts that detail how to install OpenCV 3.0 on both python 2.7+ and Python 3+. As I mentioned last week, OpenCV 3.0 is finally here!Īnd if you’ve been paying attention to my Twitter stream, you may have noticed a bunch of tweets regarding installing OpenCV on OSX and Ubuntu (yep, I’ve been tweeting a lot lately, but that’s just because I’m so excited about the 3.0 release!)
