How to install Numpy & Scipy for Python 3.3 on Moutain Lion

Question

Haven't found a working solution as of yet. I have three different versions of Python on my system, the default bundled with OSX (2.7.2), 2.7.3 installed via homebrew and 3.3.0 installed via homebrew. Running pip install numpy or pip install scipy will install it for the 2.7.3 version.

How can I install numpy and scipy for Python 3.3.0 on Moutain Lion?

Answer 1

you need to call pip3 instead of pip. Homebrew installs pip3 with python3.

I just tried pip3 install numpy on my OSX 10.7.5 python 3.3.0 machine and it failed. It looks like numpy v1.6 is not compatible but numpy v1.7 (beta, not available via pip3) is.
