Best way to solve this is to download unofficial binaries from - http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy.
In my case that will be scipy‑0.14.0.win‑amd64‑py3.4.exe.

You can try the anaconda Python distribution that includes scipy and many scientific packages: https://store.continuum.io/cshop/anaconda/
