Failed to run first cell of notebook: `scipy` was not installed by default

[carrollgt91]

I had to manually pip install scipy after running through the local setup in order for the first cell in the test notebook to execute.

I thought that it should have automatically installed with scikit-learn, but it did not seem to, for some reason.

Scikit-learn doesn't install Scipy, check here: http://scikit-learn.org/stable/install.html Anyway, the local setup now includes running pip install -r requirements.txt which installs Scipy correctly. @iamtrask I think this can be closed?
