Heroku cedar14 stack buildpack with Python, OpenCV, Numpy, SciPy and Matplotlib

What

This buildpack provides a self-contained environment for python applications that need: OpenCV, Numpy or Scipy.

Why

• Existing OpenCV buildpacks didin't work for me or python support simply wasn't there.
• All sorts of issues with heroku python buildpack and OpenCV.
• All sorts of issues with cedar stack default python and OpenCV.
• Compiling things in a one-off dyno is slow.

How

A complete environment was created using the Dockerfile file based on the heroku cedar stack v14.

This buildpack will download that environment and place it in your /app/.heroku folder. This includes the following:

• Python-2.7.10
• Opencv-2.4.11 (with python support)
• Numpy-1.11.1
• Scipy-0.18.0
• Matplotlib-1.5.3
