I am trying to get matplotlib to work under Windows 7 (64-bit) using Python 2.7 and Eclipse with the PyDev plugin. I installed NumPy from http://www.lfd.uci.edu/~gohlke/pythonlibs/ .
The problem is that I am writing the following code in Eclipse:
import matplotlib.pyplot as plt
plt.figure()
I get the following error:
Traceback (most recent call last):

ImportError: cannot import name namedtuple
Also with NumPy when I write the following code in Eclipse:
import numpy
add(array([-1.2, 1.2]), array([1,3]))
I get the following error:

from numpy import ndarray, amax, amin, iscomplexobj, bool_
ImportError: cannot import name ndarray
From the command line, both NumPy and matplotlib work fine, I added both matplotlib and NumPy from preferences -> pydev -> interpreter python. What could be the problem? Also, what alternative could I use to create graphs using Python?
