copied!<p>In case someone else comes to this like I did...</p> <p>The <a href="https://stackoverflow.com/questions/9819968/running-scipy-on-heroku/10632272#10632272">excellent answer</a> on this question from <a href="https://stackoverflow.com/users/1400423/coshx">@coshx</a> sadly no longer works (at least I could not get it to work). What I did, however was the following:</p> <ol> <li><p>I forked <a href="https://github.com/wyn/npscipy-binaries" rel="nofollow noreferrer">npsicpy-binaries</a> repository from @coshx and changed all the tar files such that they do not have <code>venv</code> as the root folder inside (my fork is <a href="https://github.com/kmp1/npscipy-binaries" rel="nofollow noreferrer">here</a>)</p></li> <li><p>I forked the <a href="https://github.com/wyn/npsp-helloworld" rel="nofollow noreferrer">npsp-helloworld</a> repository from @coshx and made it use a <code>requirements.txt</code> file instead of the setup.py (my fork is <a href="https://github.com/kmp1/npsp-helloworld" rel="nofollow noreferrer">here</a> - this means that you can use the whole pip approach).</p></li> <li><p>I forked the <a href="https://github.com/heroku/heroku-buildpack-python" rel="nofollow noreferrer">heroku-buildpack-python</a> repository from Heroku, took the <a href="https://github.com/wyn/heroku-buildpack-python/blob/master/bin/steps/npscipy" rel="nofollow noreferrer">npscipy</a> file from @coshx and changed it to work with this latest version of the build pack (my fork is <a href="https://github.com/kmp1/heroku-buildpack-python" rel="nofollow noreferrer">here</a> - you can see that there is no venv set up, for example).</p></li> </ol> <p>After doing those three things I have the <a href="https://github.com/wyn/npsp-helloworld" rel="nofollow noreferrer">npsp-helloworld</a> application working perfectly. You just need to make sure you set the buildpack appropriately when creating the application and you are good to go:</p> <pre><code>$ heroku create --stack=cedar --buildpack=https://github.com/kmp1/heroku-buildpack-python.git </code></pre> <p>NOTE: I haven't worked out how to make my own binaries yet, so the three libraries (scipy, numpy and scikit-learn) are not the latest versions so make sure when you install it you do (if anyone can build these I would gladly accept a pull request for them):</p> <pre><code>pip install scipy==0.11.0 pip install numpy==1.7.0 pip install scikit-learn==0.13.1 </code></pre> <p><em>By the way - I am really sorry if I have not done things in the correct way, etiquette-wise. I'm still learning git and this whole open source thing.</em></p>
