[Tutor] numpy import failure

[Ezra Kahn]

I am a total newb, learning to ween myself off of Matlab.  I am working 
off of EPD6.1, and I cannot get numpy to import.  Python keeps sending 
me back this:

Traceback (most recent call last):
   File "<pyshell#0>", line 1, in <module>
     import numpy
ImportError: No module named numpy

How do I trouble shoot this?

Thanks

Ezra
