In this post we will install OpenCV and Python on MacOS

Install XCode

sudo xcodebuild -license sudo xcode-select install

Install Homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" brew update #To resolve brew error git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow #To resolve brew error git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow brew update --force --quiet`

Install Python3

#Installing python2 and python3 if not exist brew install python python3 #Symlink python2 and python3 brew link python brew link python3 #If python already installed then it may ask for an upgrade brew upgrade python brew upgrade python3 #Verify python installed correctly which python2 which python3 #Check python version python2 --version python3 --version

Install OpenCV

# Install OpenCV 3 with Python2 and Python3 bindings brew install opencv@3 #add OpenCV site-packages path to global site-packages echo /usr/local/opt/opencv@3/lib/python3.9/site-packages >> /usr/local/lib/python3.9/site-packages/opencv3.pth #In case of the path not found, update the python version in the path #if python version is Python 3.9.2 then the path should be /python3.9/

Test OpenCv

python3 import cv2 print(cv2.__version__) import numpy as np print(np.__version__)

Install OpenCV in Virtual Environment

Install virtualenv

pip install virtualenv virtualenvwrapper echo "VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3" >> ~/.bash_profile echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bash_profile source ~/.bash_profile

Create Environment

mkvirtualenv opencv-py3 -p python3 workon opencv-py3 pip install numpy ipython scipy pandas scikit-image scikit-learn matplotlib cd ~/.virtualenvs/opencv-py3/lib/python3.9/site-packages/ ln -s /usr/local/opt/opencv@3/lib/python3.9/site-packages/cv2.cpython-39m-darwin.so cv2.so deactivate

Test OpenCV in virtualenv

workon opencv-py3 ipython import cv2 print(cv2.__version__) import numpy as np print(np.__version__) deactivate
