I have a very similar question to this question, but still 1 step behind.
I have only one version of python 3 installed on my Windows 7(sorry) 64-bit system.
I installed numpy following this link - as suggested in the question.
The installation went fine but when I want to import
import numpy
Import error:No module named numpy
Support for Python 3 was added in NumPy version 1.5.0, so to begin with, you must download/install a newer version of NumPy.
