Python 2.7 & PyDev - matplotlib and NumPy not working - python

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 when I write the following code in Eclipse:
import matplotlib.pyplot as plt
plt.figure()
I get the following error:

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 the command line both NumPy & matplotlib both run fine, I have 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?

Works for me. Very probably you have added matplotlib and numpy directories to your PYTHONPATH, such that matplotlib.collections is imported instead of the collections module from the Python standard library. Try remove matplotlib and numpy directories from the PYTHONPATH in the Eclipse > PyDev > Python interpreter settings.

I was having the same issue, but follow the instructions at the bottom of the page and installed the SciPy SuperPack. Worked like a charm on Mountain Lion:
https://github.com/fonnesbeck/ScipySuperpack
After it installs numpy you can always just ctrl-C out of the other packages

No Calendar package is imported

When trying to run the following script:

plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()

Why? Does anybody know how to solve this issue?
I have fixed it. there was a different python program I named it as Calendar.py :(. I have deleted that file from "config/scratches/" and it has fixed the issue.
Also I have deleted the two versions of Tkcalendar installed

Importing packages on Anaconda on Windows won't work if PYTHONPATH is set

I've installed Anaconda 4.1.12 x64 on Windows and, when running python apps on command line, it imports packages as numpy just fine... unless I set the environment variable PYTHONPATH. I want to run Caffe on windows, and thus I need to put the Caffe binding on its path.
My test case is this small test.py file:
import numpy as np
print np
If I python test.py it on the command line, with PYTHONPATH not set, I get this:
<module 'numpy' from 'C:\Anaconda2\lib\site-packages\numpy\__init__.pyc'>
Seems fine. But if I set PYTHONPATH, the output is this:

Please help
I soled the issue by uninstalling python27, reinstall it again and install extension
pip install matplotlib-1.5.0-cp27-none-win_amd64.whl
this will install automaticaly numpy extension

I've searched through the site-package file and I see that io exists so I'm not really sure whats's missing.
Not sure why it worked but installing numpy +mkl instead of numpy vanilla from the unofficial binary site on UCI got around this for me.

You are trying to use a .so file in Mac OSX! .so files work on Linux; Mac OSX works with .dynld files. You probably may want to verify your NumPy Installation.
Assuming you are using OSX Lion, please see here for how to install NumPy on the OSX.
