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.
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:
Python 2.7.10 (default, Jun 1 2017, 18:51:46)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux2

/usr/local/lib/python2.7/site-packages
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 installed pywinauto using pip install pywinauto.
OS: Windows 10
Python: 3.6.2
When I run python and try to import pywinauto, I get the error:

Any ideas how to fix this?
I have the same issue today and fixed it by pip install comtypes==1.1.7.
It caused by comtypes library which release a new version 1.1.8 at Dec.26. Downgrade to previous version, it works well now.
It should be fixed in comtypes==1.1.9. Please check.
The problem was introduced in comtypes==1.1.8. My fault.
Try using a different version of python (e.g. 3.7.5 or 3.8):
https://github.com/pywinauto/pywinauto/issues/887
"Had the same issue with Python 3.7.6 and 3.8.1. Issue does not occur in 3.7.5 or 3.8.
I think this will be fixed in 3.8.2 ( but not sure yet)"
Try this, for me works fine
Install pywin32 from https://github.com/mhammond/pywin32/releases
pip install -U comtypes
pip install six
pip install Pillow
cd c:\windows\syswow64\
regsvr32 UIAutomationCore.dll
python
import pywinauto
#and the problem should be solved
I have Win10 and python 3.9..... i don't like Win10
Another thing could be your numpy library, uninstall it and install it again.
pip uninstall numpy
pip install numpy

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 managed to break one of my virtual environments. I think I did it by installing pycrypto with pip and uninstalling it with easy_install.
This is what I get when I run python in the venv.

How can I fix this?
You should not name your file types.py as there is a standard library module with the same name (import types).
As such, Python tries to import it as part of some standard library code but it now actually imports your local types.py file, not the module it expects.
So the problem should be fixed when you rename types.py to something else.
I have installed pygtk-all-in-one-2.24.0.win32-py2.7.msi on windows, and installed gaphor by easy_install. When I try to run gaphor, I receive an import error.
PS C:\Python27\Scripts> .\gaphor.exe

Any suggestions would be appreciated!
Did you actually install pygtk? I suspect easy-install should have pulled it in automatically. Did you see any errors during the install? pygtk also requieres installing gtk+.
Do a simple test - start Python in a console (ipython?), and type:
$ python
Python 2.7.6 (default, May 6 2014, 10:57:58)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pygtk
>>> import gtk
>>>
There should be no error messages.
You can also search the disk for pygtk.py (with the file manager) and for a directory gtk-2.0 or gtk-3.0.

Please help me: how can install the Python Canopy (including scipy, matplotlib etc.)? Do I have to manually install them? I thought the installer shell script installed all these automatically. Am I missing something?

Scipy is installed into a different virtual environment (~/Enthought/Canopy_64bit/System/). In general, you should be running the Python available at ~/Enthought/Canopy_64bit/User/bin/python as described here. Also look at this article for information on how to make Canopy your default Python
