Installing numpy on mac osx (snow leopard)

I am trying to install numpy on my mac machine. Whatever I try, I end up getting this error when trying to run my python code

 import numpy as np

Also when I enter Python in my terminal it takes me to python 2.6.1 version. How do I solve this?

If you want a fairly complete scientific python environment on your Mac I would recommend the EPD free Python distribution. That will give you numpy and scipy among others.

Based on the paths in the error message, it looks like you intended to install Numpy for a Python 2.7 that you've already installed. You're getting Python 2.6 instead. This suggests a problem with your PATH environment variable. Adjust the PATH variable in your .bash_profile so that the executables for the Python 2.7 appear before the system versions in /usr/bin.

I would recommend using macports or fink as a package system.

With macports, installing numpy is as easy as

cd /opt/local/bin 
sudo ./port install py27-numpy

where py27 may be replaced with your favorite python version.
