Great! I can see that we have Python 3.6.5 installed now. Type 'help', 'copyright', 'credits' or 'license' for more information. These commands will install Python 3.6.5_1: $ brew install Д«e sure to copy the entire command + URL. It sounds good, but Python 3.7 is unsupported by Keras/TensorFlow (both are used often on this blog) and thus are not a good choice for OpenCV either.

By default High Sierra and Mojave are coming with Python 3.7 now. It is extremely important to use Python 3.6. WeвЂ™ll also install prerequisites for building OpenCV from source. In this section weвЂ™ll ensure that Python 3.6 is installed. Step #3: Install OpenCV prerequisites using Homebrew Once youвЂ™re back in bash, source your bash profile: $ source ~/.bash_profile

If youвЂ™re using nano, youвЂ™ll see the shortcut keys at the bottom of the window which demonstrate how to save (write) and exit.

Once youвЂ™re actively editing the file, append the following lines to the end to update your PATH : # HomebrewДЇrom there, save the profile. If youвЂ™re more comfortable with vim or emacs, then go for it.Д®dit your bash profile with nano using the following command: $ nano ~/.bash_profile For simplicity, I suggest the nano text editor. This script is run each time you launch a terminal. LetвЂ™s update the Homebrew definitions: $ brew updateДЄnd now letвЂ™s edit our MacвЂ™s bash profile. When youвЂ™re ready, copy the entire command below to install Homebrew: $ /usr/bin/ruby -e '$(curl -fsSL )' Homebrew runs on Ruby which is a popular programming language. Step #2: Install HomebrewДЇor this step weвЂ™re going to install the Mac community package manager, Homebrew. You can install the tools via: $ sudo xcode-select -installДЇigure 2: Installing Apple Command Line Tools on macOS.Д¬lick the вЂњInstallвЂќ button and wait about 5 minutes for the installation to complete. This is required, so that youвЂ™ll have make, gcc, clang, etc. Once youвЂ™ve accepted the license agreement, letвЂ™s install Apple Command Line Tools. To accept the license, simply scroll down and accept it. Launch a terminal and enter the following command: $ sudo xcodebuild -license To install Xcode, launch the App Store, find Xcode, and run the installation.ДЄfter Xcode has installed we need to accept a license agreement. YouвЂ™ll need to wait patiently as this figure indicates: Figure 1: Xcode is a dependency for Homebrew and therefore OpenCV 4 on macOS. To install Xcode, fire up the Apple App Store, find the Xcode app, and install. IвЂ™ll cover alternative methods (pip and Homebrew) in future installation guides (neither of these methods can be covered until OpenCV 4 is officially released).ДЇinally, weвЂ™ll test out our OpenCV 4 install and get our feet wet with a real OpenCV project.

Compiling from source allows us to have full control over the compile and build as well as to install the full OpenCV 4 build.

I post links to all my OpenCV install tutorials there.ДЇirst, weвЂ™ll install Xcode and set up Homebrew.ДЇrom there, weвЂ™ll establish Python virtual environments.

Note: If you landed on the wrong install tutorial (perhaps you want to install OpenCV on Ubuntu or your Raspberry Pi), then you should visit my OpenCV installation guides page. OpenCV 4 is packed with new features, many of which are deep-learning focused. In this blog post weвЂ™re going to install OpenCV 4 on macOS. Looking for the source code to this post?
