How to install Python 2.7 bindings for OpenCV using MacPorts

Question

When trying to \"import cv\" in python I get: \"ImportError: No module named cv\". This question has appeared in many forms, but I haven\'t found the answer that helps.

Answer 1

STEP ONE

Use Macports to install opencv.

STEP TWO

Put these two files somewhere on your PYTHONPATH (for example in your site-packages):

• https://github.com/jonmrodriguez/opencv-2.3-new-python-bindings/blob/master/cv.py
• https://github.com/jonmrodriguez/opencv-2.3-new-python-bindings/blob/master/cv2.so

STEP THREE

Create the below soft links (because cv2.so expects the dylibs to be in /usr/local but MacPorts installs to /opt/local):

cd /usr/local/lib/
ln -s /opt/local/lib/libopencv_core.2.3.dylib libopencv_core.2.3.dylib
ln -s /opt/local/lib/libopencv_flann.2.3.dylib libopencv_flann.2.3.dylib
ln -s /opt/local/lib/libopencv_imgproc.2.3.dylib libopencv_imgproc.2.3.dylib
ln -s /opt/local/lib/libopencv_video.2.3.dylib libopencv_video.2.3.dylib
ln -s /opt/local/lib/libopencv_ml.2.3.dylib libopencv_ml.2.3.dylib
ln -s /opt/local/lib/libopencv_features2d.2.3.dylib libopencv_features2d.2.3.dylib
ln -s /opt/local/lib/libopencv_highgui.2.3.dylib libopencv_highgui.2.3.dylib
ln -s /opt/local/lib/libopencv_calib3d.2.3.dylib libopencv_calib3d.2.3.dylib
ln -s /opt/local/lib/libopencv_objdetect.2.3.dylib libopencv_objdetect.2.3.dylib
ln -s /opt/local/lib/libopencv_legacy.2.3.dylib libopencv_legacy.2.3.dylib
ln -s /opt/local/lib/libopencv_contrib.2.3.dylib libopencv_contrib.2.3.dylib
