Installing the Python / Numpy / OpenCV Stack

Mac OS X 10.9 (Mavericks)

Step 1: Install Homebrew, the OS X package manager

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
brew doctor

If brew doctor reports any errors, be sure to resolve them before proceeding. Common errors include preexisting Python installations.

Step 2: Install OpenCV packages

brew tap homebrew/science
brew install opencv
mkdir -p ~/Library/Python/2.7/lib/python/site-packages
echo '/usr/local/lib/python2.7/site-packages' > ~/Library/Python/2.7/lib/python/site-packages/homebrew.pth

Step 3: Install the pep8 package

sudo easy_install pep8

Step 3: Check that it worked

Invoke the Python interpreter, and import the OpenCV and pep8 packages. If there are no errors, you're in business!

python
import cv2
import pep8
