The first is that you want to ensure the root path for both Python binaries are in /usr/local/bin - this is where Homebrew stores the Python binaries. There are two key points you need to pay attention to here. You can verify that Python 2.7 and Python 3 have been successfully installed by using which : $ which python2 We’ll then install cmake (a utility used for building, testing, and packaging software) along with Python 2.7 and Python 3: $ brew install cmake You then need to source the ~/.bash_profile file to reload the changes: $ source ~/.bash_profile $ echo "export PATH=/usr/local/bin:$PATH" > ~/.bash_profile or simply using echo and redirection: $ echo -e "\n# Homebrew" > ~/.bash_profile This can be accomplished by manually editing the file using an editor such as nano, vi, etc. Once Homebrew is installed you need to update your PATH to look for Homebrew binaries, packages, and libraries. Note: Make sure you use the “” button in the code block above to expand section - this will ensure you copy and paste the entire Homebrew install command. If not, please take the time to open the App Store and install XCode.įrom there, you’ll need to install Homebrew, a package manager for macOS, similar to Debian/Ubuntu’s apt-get : $ ruby -e "$(curl -fsSL )" I’ll assume you already have XCode installed on your macOS machine. Once you have installed dlib on your respective operating system we’ll validate the install by using Python, dlib, and OpenCV ( provided you have OpenCV installed as well), to detect facial landmarks.įrom there, I have provided additional tutorials and guides to help apply dlib to computer vision and machine learning projects, including detecting and counting blinks and building a system to recognize when the driver of a vehicle is becoming drowsy/tired (and alerting them to wake up). Please feel free to skip to the section that corresponds to your operating system. In this guide you’ll learn how to install dlib on macOS, Ubuntu, and Raspbian.
