I have installed matplotlib and of course its requirements Numpy and scipy on my pc but I get this error message when I import pylab:
>>> from matplotlib import pylab

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

When I was trying to import matplotlib, I wrote
import matplotlib.pyplot as plt
in my code.
and this error occured.

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
I am sorry for asking this question again, but I could not find any answer to my problem that helped me. I don't have much experience with python. I use python version 3.6.8 on Windows and I have already installed matplotlib, numpy and scipy. The 'pylab.py' file is also contained in the matplotlib folder. Edit: Using matplotlib.pyplot also doesn't work.
Edit: After some more trials I got the error that the module 'six.names" could not be found. The six package has been installed.

Per https://matplotlib.org/faq/usage_faq.html#matplotlib-pyplot-and-pylab-how-are-they-related, pylab is not recommended; you should use pyplot instead.
The correct way to import either is
import matplotlib.pyplot # use this
import matplotlib.pylab # only if you cannot avoid it
(pyplot and pylab are not standalone modules, but submodules of matplotlib.)
I am using pycharm for python in windows 8. I have installed the package matplotlib.
I am using python 2.7
when i do import matplotlib there is no error.
However if i do matplotlib.pyplot as plt i am getting this following errors:

can anyone help figure out what i am doing wrong?
http://matplotlib.org/users/installing.html#required-dependencies
There is a package called six which matplotlib depends on. Check to make sure it's installed, or install it from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#six
This site has packaged versions of many python modules which are easy to setup on windows, just download and run.
Also check the other dependencies to make sure you have them all, otherwise you might get another error for a different module
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.
>>> import pkgutil
>>> package = pkgutil.get_loader("matplotlib")
>>> package.filename
'/usr/local/lib/python2.7/dist-packages/matplotlib'
>>>
So where your "matplotlib" ?

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
