title: Getting Openshift 3 container to install numpy and scipy
body: <p>I have a working Pod for a Deployment in Openshift 3 Starter. This is based off an Image stream from a Docker image. However, I cannot get it to build in Openshift with the inbuilt S2I. </p>
  
  <p>The Docker option is not good as I cannot find setting anywhere to make a Image stream update and cause a redeployment.</p>
  
  <p>I tried setting it up so that a webhook would trigger an Openshift Build, but the server needs python 3 with numpy and scipy, which makes the build get stuck. The best I could do is inelegantly get a Python 3 cartridge install numpy based on <code>requirements.txt</code> and the rest via <code>setup.py</code>, but this still got stuck. I have a working webhook going for a different app that runs on basically the same layout bar for requirements (Python3 Pyramid with waitress).</p>
