To install Xcode, fire up the Apple App Store, find the Xcode app, and install. I’ll cover alternative methods (pip and Homebrew) in future installation guides (neither of these methods can be covered until OpenCV 4 is officially released).įinally, we’ll test out our OpenCV 4 install and get our feet wet with a real OpenCV project.
#GUIDE TO INSTALL PYTHON ON MAC FULL#
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.įirst, we’ll install Xcode and set up Homebrew.įrom there, we’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 we’re going to install OpenCV 4 on macOS. This is really only ever preferred when you want to really customize the binary by setting certain options/flags during the build process.Looking for the source code to this post? Jump Right To The Downloads Section Install OpenCV 4 on macOS Most people don't do this since the binaries are alreay built for them. The last, and most uncommon, method is to install Python from its source code. Once you've opened the installer, follow the instructions and Python will be installed for you.

In my case I'd be downloading Mac OS X 64-bit/32-bit installer. Just make sure you download the installer that matches your CPU architecture type (32 or 64-bit). I'd recommend using the installer since it'll handle everything for you. Once you've clicked on the version you want, you should see a list of downloads for different operating systems and package types (like source code tarballs, installers, etc). The latest version 2 and 3 links are at the top.
To install, just click the link above, then click on the version you want.
#GUIDE TO INSTALL PYTHON ON MAC UPGRADE#
If you want to upgrade to the latest 2.7.x version or upgrade to Python 3, you can get a binary directly from the Python website. This will show you a list of Python-related packages that can be installed. To see all the versions available, search Homebrew with this: $ brew search python If you'd rather have Python 3, just replace python with python3. To install Python 2.7.x, just type: $ brew install python You can install a few different versions of Python, including 2.7.x and 3.5.x. Now that you know what Homebrew is and have it installed, we can get on to installing Python. To install Homebrew, just follow the instructions on their website (which I linked to at the beginning of this section). For example, here are just a few things I've installed with it: android-sdk, go, mongodb, sqlite, git, imagemagick, lua, python3. It makes it much easier to install all the various tools you might need. Homebrew lets you install, update, and uninstall packages from the command line, just like apt-get does for Ubuntu. According to their website, Homebrew is "the missing package manager for OS X". Install Python with Homebrewįirst of all, if you don't know what Homebrew is and you use Mac OSX, you should.

Now, keep in mind that Mac OSX (10.8) already comes with Python 2.7 pre-installed, so these instructions will only really be helpful if you need to upgrade versions or need a better way to manage installations (like with Homebrew).
