Install OpenCV Python with AnacondaĪnaconda is a good tool for Python application development. Test a webcam with ().In this OpenCV tutorial, we learn how to install OpenCV with Anaconda using pip command, and then verify the installation using a simple Python code to read and display an image.

You can install whatever version you want. In the meantime, let's get the `cv2.so` for each version of Python. I'll just need to add the correct `cv2.so` to your Python's site packages. If I want both versions to have OpenCV, I can. I have `Python 3.6` and `Python 2.7` installed on my system. Now we need to link it to our version of Python. Okay, so we have the OpenCV version we're going to use and where it's located. We're very close to getting the `cv2.so` we need. This is the OpenCV Version we want to use. You'll want the highest version number listed here, in my case it's `3.3.1_1`Īwesome. In my case, the numbers `3.3.0_3` and `3.3.1_1` are different versions of OpenCV. ![]() Now, let's go into the `opencv` directory. To see what's in the Brew Cellar, do this: Since we installed OpenCV with Homebrew, the package was should be listed in homebrew's Cellar (`/usr/local/Cellar/`) $ brew install opencv3 -with-contrib -with-python3 Install OpenCV with Homebrew including Python3 Not using `pipenv`? Run `pip install opencv-contrib-python -upgrade` (cfestart) $ pipenv install opencv-contrib-python This guide is to help you get it installed on your Mac. OpenCV, aka Open Computer Vision, is an incredible library for doing everything from Face Recognition, Object Recognition, to edge detection, image manipulation, and much more.
