Here I assume that the virtual environment exists in the venvdirectory. Open a command prompt and cd to the directory where your virtualenv is installed. If you're using a virtual environment, there is one more step to get Python to recognize the OpenCV package. So far I've assumed you're working with the standard Python installation. Type "help", "copyright", "credits" or "license" for more information.
BREW INSTALL OPENCV@2 INSTALL
First install the opencv3 package with Homebrew, and then tell Python 3 where to look for the OpenCV binary: There are two steps to correctly install Python support. I’ll assume that Homebrew is up-to-date and brew doctor doesn't bring up anything serious before installing OpenCV.
What follows are the instructions to correctly install. Even though OpenCV includes the Python 2 bindings by default, the same is not true of Python 3. This seems especially true when trying to use the Python bindings that OpenCV provides.
Usually Homebrew makes dependency management a breeze, but OpenCV is a curious exception to this rule. Since our research team all develops on OS X, we also make use of the Homebrew package manager. It’s very useful for implementing computer vision algorithms, but getting the library installed properly isn’t always easy. INTRODUCTIONĭo you want to use OpenCV, but can't get it to work with Python 3? You've come to the right place! Here at Gravity Jack we tackle computer vision problems using OpenCV as one of the tools in our arsenal.
