Heroku buildpack with Python, OpenCV, Numpy and SciPy

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
• Pip-7.1.1
• Setuptools-18.2
• Opencv-3.0.0 (with python support)
• Numpy-1.9.2
• Scipy-0.16.0
• Matplotlib-1.4.3
