I am using the following setup:
Python 3.5.2 + Matplotlib 1.5.x (Raspberry Pi)
I have added backend :tkagg to my rc file.
If I run get_backend() it returns "tkagg"
However, when I try to import matplotlib as follows:
Python 3.4.2 (default, Oct 19 2014, 13:31:11)
[GCC 4.9.1] on linux
Type "copyright", "credits" or "license()" for more information.
>>> import matplotlib as mpl
>>> mpl.use('tkagg')
>>> import matplotlib.pyplot as plt
I receive the following traceback:
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>

from matplotlib.backends import _tkagg
ImportError: cannot import name '_tkagg'
Why isn't matplotlib being imported correctly?
I basicly follow the instruction in this post:
tkagg backend problems
Then used git to get the source:
sudo git clone git://github.com/matplotlib/matplotlib.git
Then did build/install using Python3.4:
sudo python3.4 setup.py install

Make sure that you have installed pandas in the proper directiry:
pip install pandas
If you have already done so, it would be worth upgrading pandas:
pip install pandas --upgrade
Hi I got the same error today when I developed a pyqt project. I found there are two "pandas" when I uninstalled one then tried to install again. What I have done was uninstalling both two "pandas", then install the latest version, then it works. Although I solved this on Windows, but hope it is helpful to you.
I recently installed shap, which requires pillow>=4.3.0 as:
$ pip3 install shap
Installing collected packages: shap, pillow
Successfully installed pillow-6.0.0 shap-0.29.2

Any tips as how to fix this?
Well, none of the answers suggested in this related post worked for me, so I ended up completely cleaning and reinstalling python3. From there, installing the necessary packages in a virtualenv as cleanly as possible seemed to resolve the issue...
The aiohttp module was installed successfully
But can not be imported as below info

import _ssl # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
The error above is
ModuleNotFoundError: No module named '_ssl'
So the real problem is my python3 can not import the module _ssl
My python 3.5 was installed from source code. Below are the correct ways to make python 3.5 have _ssl.
1. install openssl-devel by yum(My OS is CentOS)
2. compile your python source code with command (./configure && make && make install)
I've been writing a reddit bot for a while now and recently moved it to a different system. There I've installed the same packages as on the previous system.
The bot is Python3 based so I install praw:
$ sudo pip3 install praw
[...]
Which went just fine as expected, but now when I import praw:
$ python3

from prawcore import (Authorizer, DeviceIDAuthorizer, ReadOnlyAuthorizer,
ImportError: No module named 'prawcore'
Even after manually adding the path to the module, I can't import praw.
>>> import sys
>>> sys.path.append('/usr/local/lib/python3.4/dist-packages/')
>>> import praw
Traceback (most recent call last):

from prawcore import (Authorizer, DeviceIDAuthorizer, ReadOnlyAuthorizer,
ImportError: No module named 'prawcore'
With python(2), it seems to be working just fine.
How can I get my system to successfully import praw?
From reddit.com/r/redditdev:
pip3 install praw --upgrade --force-reinstall
did the job. Apparently something went wrong during the initial installation.
This is a script that I want to start to use. I have seen this as a working version on a few location. Any one has an idea why this will not execute on my mac system. I am open to all ideas to solve this issue.
from urllib.request import urlopen
html = urllib.request.urlopen("http://www.google.com")
print(html.read())
I get this as the output when executed.

It is better that you install Anaconda; this application installs some Python package on your computer. Then write following line in Conda Prompt:
conda install -c conda-forge requests
After all, use Spyder application which has been installed with Anaconda.
