Installing OpenCV 3.3 with Python 3.6.2 on MacOS Sierra 10.12
OpenCV 3.3 is out since August 2017. It comes with an optimized DNN module - so I want to take a “Deep” look at it.
Installation
Update Python, create virtualenv
brew uprade python3
brew install cmake pkg-config jpeg libpng libtiff openexr eigen tbb
mkvirtualenv cv33_p3 -p python3
pip install numpy matplotlib scikit-image
(^ Make sure you are in the newly created virtual env.)
Download Sources
cd ~
mkdir opencv-source
cd opencv-source
wget -O opencv.zip https://github.com/opencv/opencv/archive/3.3.0.zip
wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/3.3.0.zip
unzip opencv.zip
unzip opencv_contrib.zip
Compile Sources
I Install opencv3.3 into a seperate (non standard) /usr/local/openc3.3 so it does not conflict with my current development in opencv 3.2.
cd opencv-3.3.0/
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local/opencv3.3 \
-D OPENCV_EXTRA_MODULES_PATH=~/work/opencv-source/opencv_contrib-3.3.0/modules \
-D PYTHON3_LIBRARY=/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/config-3.6m-darwin/libpython3.6.dylib \
-D PYTHON3_INCLUDE_DIR=/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/include/python3.6m/ \
-D PYTHON3_EXECUTABLE=$VIRTUAL_ENV/bin/python \
-D BUILD_opencv_python3=ON \
-D WITH_CUDA=OFF \
-D BUILD_EXAMPLES=ON ..
(Make sure it finds your python3 Interpreter/ Library / numpy)
