I am using Ubuntu 16.04 and Python 2.7, and I have set up a virtual environment (virtualenv) using a pypy interpreter.
I even installed succeffully the matplotlib library.
However, we it comes to using it on my own code I get this error messagge:
Traceback (most recent call last):
File "my_script.py",
line 20, in
import matplotlib.pyplot as plt
File "/home/.../venv/site-packages/matplotlib/pyplot.py",
line 115, in

import matplotlib.backends.tkagg as tkagg
File "/home/.../venv/site-packages/matplotlib/backends/tkagg.py",
line 9, in
from matplotlib.backends import _tkagg RuntimeError: Cannot dlopen tkinter module file
What can I do to fix it?
EDIT: The solution proposed here is the same, but I think that the problem (pypy and matplotlib) and the error message are quite different.

I have installed matplotlib on a Windows 10 machine using
pip3 install matplotlib
I get a message that it's using the wheel
matplotlib-3.4.1-cp39-cp39-win_amd64.whl1
When I type import matplotlib in a python 3.9 shell, I get the following message:
Traceback (most recent call last):

from matplotlib._path import (
ImportError: DLL load failed while importing _path: The specified module could not be found.
I ran the installation under Windows Terminal, as an administrator.
How can I fix this? I don't want to install anaconda or WinPython, if I can avoid it. I just want matplotlib to work.
This issue is present again with matplotlib 3.3.2, 3.3.3 and 3.3.4. .
matplotlib 3.3.0 3.3.1 work.
I found a solution by mkunzBGC on Github:
https://github.com/matplotlib/matplotlib/issues/18292#issuecomment-792634734
The downgrade to matplotlib 3.3.1 worked for me.
I figured it out. If you have already installed matplotlib, but the error still comes about. Then you have to download Microsoft C++ from their website. https://www.microsoft.com/en-US/Download/confirmation.aspx?id=48145
install Microsoft c++ then you can try again to run your code. it has worked for me like magic. I got the solution from a youtube video.

I have set up a virtual environment and when I try to run matplotlib on it, I get the following error:

ImportError: No module named _tkinter
From what I understand, I need to
set the environment variables correctly in the activate script
or I can symlink tkinter folder to virtualenv python2.7.
I have followed the steps here: TKinter in a Virtualenv, but I am still getting the error.
Steps that I followed are:
To virtualenv/bin/activate, I added
TK_LIBRARY=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TKPATH=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TCL_LIBRARY=/usr/lib
export TCL_LIBRARY TK_LIBRARY TKPATH
In virtualenv/lib/python2.7 I ran, ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_tkinter.so
Note that when I am using the system Python as an interpreter on PyCharm, matplotlib works fine which gives me a feeling that Tkinter is available somewhere on my system but I am failing to call it from my virtual environment.
The link above seems to be working for Ubuntu. I am wondering if anyone know what is the analogous version for Mac.
Thanks!
If you are not specific to using tkinter in virtual environment then you can use the following lines of code:
import matplotlib
matplotlib.use(‘TkAgg’)
import matplotlib.pyplot as plt
I hope this solves the problem.
I'm trying to run a python script however I get the message

It seems some of these errors are concerning Matplotlib, however when I run
pip list
It seems that I do have installed matplotlib
pip list output:
cycler (0.10.0)
functools32 (3.2.3.post2)
matplotlib (2.0.2)
numpy (1.11.3+mkl)
opencv-python (2.4.13.2)
pip (9.0.1)
pyparsing (2.2.0)
python-dateutil (2.6.0)
pytz (2017.2)
scikit-learn (0.18.1)
setuptools (28.8.0)
six (1.10.0)
wheel (0.29.0)
My python version is 2.7.13, I'm running on a 64-bit Windows system.
If it's not your python version, make sure you have Microsoft Visual C++ 2008 64bit installed as it's used by matplotlib check in Control Panel > Programs
I am having trouble getting my matplotlib library to work. I am running it on a virual environment, and I have installed numpy, and matplotlib. I first open my virtual environment, activate python, then I enter,
import matplotlib
everything goes fine, but then I enter,
import matplotlib.pyplot as plt
I get the error,
Traceback (most recent call last):

I have tried a number of different solutions to no avail. What could be the problem?
Use the below mentioned commands:
import matplotlib
matplotlib.use(‘TkAgg’)
import matplotlib.pyplot as plt
This worked for me. I hope it helps.
I just installed Anaconda. I already had Spyder 3.0.0 installed on my Windows 8.1 (64 bit). I also already had Python 3.4 installed. But, after installing Anaconda, I went into Preferences and pointed the Python executable to the Anaconda3 folder to utilize the 3.5 version. But when I started up Spyder again, got the following error:
An error ocurred while starting the kernel

Any ideas?
Suggestion:
rename your directory "C:\WinPython-64bit-3.4.4.2" in "C:\WinPython-64bit-3.4.4.2bis"
relaunch your Anaconda Spyder
if it doesn't help, rename it back to "C:\WinPython-64bit-3.4.4.2"
