Notice how I am specifying -p python3 to explicitly indicate that we want to create a virtual environment using the Python 3.4 binary.ДЄfter the mkvirtualenv command has executed, we are dropped into our cv3 virtual environment. This virtual environment will also hold any extra packages we want to store for computer vision and image processing development: $ mkvirtualenv cv3 -p python3 LetвЂ™s create our cv3 virtual environment that OpenCV will use to compile our Python 3.4 bindings against. Source /usr/local/bin/virtualenvwrapper.shДЇollowed by reloading our.

WeвЂ™ll also need to update our ~/.bash_profile file again by adding the following lines to the bottom of the file: # Virtualenv/VirtualenvWrapperД®xport VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 I am using pip3 to indicate that the virtualenv and virtualenvwrapper packages should be installed for Python 3.4, not Python 2.7 (although these these packages can be used for both Python versions).

Using virtualenv and virtualenvwrapper is definitely not a requirement to get OpenCV installed on your OSX machine, but I highly recommend using these packages! Being able to create separate Python environments for each of your projects is incredibly useful, so definitely consider using them!ДЄnyway, letвЂ™s install virtualenv and virtualenvwrapper : $ pip3 install virtualenv virtualenvwrapper Now we can focus on setting up our Python 3.4 environment for the OpenCV compilation. LetвЂ™s reload our ~/.bash_profile to ensure the changes have taken affect: $ source ~/.bash_profileДЄnd lastly, letвЂ™s confirm that Python 3.4 has been installed: $ which python3 We also need to update our PATH in ~/.bash_profile (if the file does not exist, create it) to indicate that Homebrew packages should be used before any system packages: # Homebrew OSX doesnвЂ™t ship with a copy of Python 3, so we need to install it via Homebrew: $ brew install python3

To install Homebrew, just fire up a terminal and copy and paste the following commands: $ cd ~ WeвЂ™ll be using Homebrew to help us install and manage some of OpenCVвЂ™s prerequisites and dependencies. Homebrew is a package manager for OSX, similar to UbuntuвЂ™s apt-get.

The download itself is quite large (> 2gb), and AppleвЂ™s content delivery servers arenвЂ™t the fastest in the world, so youвЂ™ll probably want to go for a walk and get some fresh air while Xcode installs. Simply search for Xcode, click Get, followed by Install App, and your download will start: Figure 1: Installing Xcode on OSX. Installing Xcode is very straightforward and can be accomplished by using the App Store application. Step 1: Install XcodeД«efore you can compile OpenCV on your system, youвЂ™ll first need to install Xcode, which is a set of developer tools provided by Apple for OSX and iOS development. With that said, letвЂ™s go ahead and get started installing OpenCV 3.0 with Python 3.4 bindings on OSX. If youвЂ™re looking for more details on each step and command, please see the previous post where I go into a bit more detail. As youвЂ™ll notice, most of the steps are very similar (and in some cases, identical), so IвЂ™ve trimmed down the explanations of each step to reduce redundancy.

#BREW INSTALL OPENCV FOR PYTHON3 HOW TO#

How to Install OpenCV 3.0 and Python 3.4+ on OSXДЄs I mentioned at the top of this article, I have already covered how to install OpenCV 3.0 with Python 2.7 bindings on OSX in a previous post.

This tutorial still works perfectly if you are using OSX Yosemite or prior, but if you want to install OpenCV on the newer El Capitan and macOS Sierra please use this freshly updated tutorial.

UPDATE: The tutorial you are reading now covers how to install OpenCV 3.0 with Python 3.4+ bindings on OSX Yosemite and below. In the rest of this article, IвЂ™ll show you how to compile and install OpenCV 3.0 with Python 3.4+ bindings. ItвЂ™s been a long time coming - and after being stuck in Python 2.7 land for many years, itвЂ™s a great feeling to fire up that Python 3 shell and be part of the future of the Python programming language.

ThatвЂ™s right! With the OpenCV 3.0 gold release, we officially have Python 3 support. Today IвЂ™m back again with another OSX tutorial - only this time we are going to compile OpenCV 3.0 with Python 3.4+ bindings! Two weeks ago we kicked off the OpenCV 3.0 install-fest with a tutorial on how to install OpenCV 3.0 and Python 2.7 on OSX.
