installed matplotlib
i'm trying to do this:

i get this:

any idea?
You need to install urllib.
This is required by matplotlib
Look Install urllib from : https://pypi.python.org/pypi/urllib2_file/0.2.1
Or if you was instaled pip you can use sudo pip install urllib

I tried several ways such as reinstalling matplotlib and pasting new "Msvcp71.dll" and "Msvcr71.dll" files in my system folders. Anyways to solve this problem?
... reinstall the matplotlib python package with this argument --ignore-installed:
pip3 install matplotlib --user --ignore-installed

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
What I have understood since trying to fix this is that I installed matplotlib but python does not utilize it to plot something.
I encountered some error messages like this:
from matplotlib import pyplot

Reason: image not found
I googled image not found error, matplotlib reinstall and etc... but nothing has worked.
Does this have something to do with version of os x? I am using yosemite.
Here information.

So where your "matplotlib" ?

As far as I remember it used to work but now I get error message. I even re-installed it but didn't help. How could I fix it?
It may be that you are missing:
import matplotlib as mpl
However, if that does not work. Reinstall the Anacoda distribution, then make sure you have numpy and scipy installed.
The top of your program is then:
import numpy as np
import scipy
import matplotlib as mpl
import pylab
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
