Sudo apt-get install libatlas-base-dev libjasper-dev libqtgui4 python3-pyqt5. Finally, we can enter a wonderfully simple command to install opencv: sudo pip install opencv-contrib-python. For those of you also used to installing OpenCV manually I am sure you will be as happy as I am! Now let’s just make sure that OpenCV is working. In this post, we will provide step by step instructions for installing OpenCV 3.3.0 (C and Python) on MacOS and OSX. If you are still not able to install OpenCV on your system, but want to get started with it, we suggest using our docker images with pre-installed OpenCV, Dlib, miniconda and jupyter notebooks along.
This is now outdated as Brew finally added opencv 2.4.9, See here
1. First of all I’ll be using the package manager Homebrew to simplify things, you can get it here: http://brew.sh/
The reason I’ve decided to use Homebrew was because it installs packages into their own directory which makes everything nice and easy to find. Mummy game free for pc. I tried macports but didn’t like it.
2. Once you have brew installed you can go ahead and and add homebrew/science which is where OpenCV is located using:
Install Opencv Python Mac Os
3. As of the time of writing Homebrew only supports OpenCV 2.7.1 so we need to make a few changes:
The ‘formula’ for OpenCV should now be open in whatever you set the default editor to be, it’s vim by default but if you want to change it you can run the following replacing ’emacs’ with whatever your favorite text editor is.
4. Look for the following lines
Go ahead and replace the highlighted lines with
5. If you want to see other possible options such as when compiling (such as using tbb) you can use info
Go ahead and install OpenCV now
6. You’re done! You can find OpenCV at
1. Navigate to your python path, if you don’t know where it is when you installed Python you can find it in your .bash_profile or using
in my case we’ll be using
2. Once there we need to link our compiled OpenCV files, create a symlink using
Mac Upgrade Python 3
3. You’re done! You can make sure it works by running python and typing
