The current version of Python3 is 3.5.2 when I import matplotlib it retuned the following error

It seems that tkinter has already been intalled.
I have installed tk and tcl by
sudo apt-get install tk-dev
sudo apt-get install tk8.6-dev
And OS is Ubuntu 14.04.
I think it is the reason that TK was not configured on Python3, but I'm not sure. Many people said I should rebuild and reinstall Python3 with tk, however I don't think it is an elegant way to solve this problem.
How can I fix this problem?
If you are having trouble with a matplotlib backend try selecting a different one.
Matplotlib caters for many different scenarios and uses.
On Linux, I use the following code to select whichever backend is available and works first.
import matplotlib
gui_env = ['TKAgg','GTKAgg','Qt4Agg','WXAgg']
for gui in gui_env:
try:
matplotlib.use(gui,warn=False, force=True)
from matplotlib import pyplot as plt
break
except:
continue
or if you are going to be creating an image file rather than displaying it
Use:
matplotlib.use('agg')
from matplotlib import pyplot as plt
Edit:
Based on your comments try this and see if you get a result that works.
import matplotlib
gui_env = [i for i in matplotlib.rcsetup.interactive_bk]
print ("I will test for", gui_env)
for gui in gui_env:
print ("testing", gui)
try:
matplotlib.use(gui,warn=False, force=True)
from matplotlib import pyplot as plt
print (" ",gui, "Is Available")
plt.plot([1.5,2.0,2.5])
fig = plt.gcf()
fig.suptitle(gui)
plt.show()
print ("Using ..... ",matplotlib.get_backend())
except:
print (" ",gui, "Not found")

I have installed python 2.7.10 in CentOS 6.5. Then I installed matplotlib using pip. However, I am getting the following error when trying to import matplotlib.pyplot.

tkinter seems to be installed.
"Package tkinter-2.6.6-66.el6_8.x86_64 already installed and latest version"
I have _tkinter.so module in python2.6/lib-dynload, but nothing related to tkinter under python2.7/lib-dynload.
/usr/lib64/python2.6/lib-dynload/_tkinter.so
/usr/local/lib/python2.7/lib-tk/test/test_tkinter
Also, I verified sys.path in python to get the following:

This may be a problem with your python library path. Check to see where tkinter is installed, and make sure that you have that available to your Python interpreter. Can you import anything else from tkinter?
Try to install tkinter as they said ”no module named _tkinter“.
You can do so with that command:
sudo apt-get install python-tk
I have two pythons in my mac, they are python 3.4 and 2.7

This is your problem.

Use this sequence of commands to get to where you want.
pip uninstall matplotlib
rm -rf /tmp/pip-build-root/
brew update

Simple solution to the issue that worked for me:
1- in terminal type $open -a Finder /usr
2- right click on local and do get info
3- unlock the lock at the bottom
4- click + sign and add your user to the list and give read/write privileges
5- click on the gear sign at the bottom and choose apply to enclosed items to recurse under that directory and assign privileges too all directories beneath it.
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

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" ?

I have NumPy and SciPy installed and working. I'm using Python 2.5 (MIT Intro to Programming course) so I've been installing the packages with .exe files instead of Pip or Anaconda. With MatPlotLib, I get the following errors during installation:
could not create: matplotlib-py2.5
could not create: python 2.5 matplotlib-1.0.0
could not set key value: "C:\Python25\Removematplotlib.exe" -u "C:\Python25\matplotlib-wininst.log"
I have a MatPlotLib folder in Python's Lib/site-packages directory. Importing matplotlib into IDLE works fine. But when I try to import pylab:

I've looked around on different message boards but can't find anyone else with this issue.
Any ideas?

Here is the following issue:
I am trying to generate a few graphs using Matplotlib and Python. As I hear from a majority of the solutions3.. there seem to be compatibility issues between matplotlib and 64bit architectures.
I have installed Matplotlib from here

Thanks.
matplotlib is failing to connect to any X server for its GTK display.
There are a couple of options here:
Run a local X server and enable X11 forwarding in your ssh client, to display the output on your local machine. You can verify this is working by checking that the $DISPLAY environment variable is set on the server.
Call matplotlib.use(...) to specify a different display back-end, for example rendering to pdf file, before importing pyplot, e.g.
import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt
