I'm getting KeyError: 'scale'
when I'm trying to run import matplotlib.pyplot
I redownloaded the matplotlib then ran the code but still getting the same error.
I've also opened the new Jupyter notebook and only ran "import matplotlib.pyplot as plt" and I'm still getting the same error. I didn't get any error when I ran "import matplotlib" only.
I would be grateful if you help me out find what's causing the error.

For those who may face the same error as me, the problem was solved by updating the version of Jupyter notebook to the latest version in my case.
It appears to be related to a version mismatch between mpl_toolkits and matplotlib. I couldn’t figure out how to upgrade mpl_toolkits, so I downgraded matplotlib, and the error went away.
pip3 install matplotlib==2.*
I had the same problem. In my case this issue was solved by remove mpl-toolkits in appdata
~/opt/anaconda3/lib/python3.7/site-packages/mpl_toolkits/
It will be helpful remove this file
Uninstall the old Matplotlib first using the command:
sudo pip3 uninstall matplotlib
Install it again using:
sudo pip3 install matplotlib
Check whether it is working or not. If not working Uninstall twice the matplotlib. Because two version matplotlib may present.
Like this method only, I solved the issue or update the anaconda to update the new version If you are using anaconda.
Hope this may work well.
I met with this problem, too. And the problem is solved by
conda install matplotlib
Hope this working.
In my case, using ipython and matplotlib installed in virtualenv, I had to install python-tk on my Ubuntu 20.04:
sudo apt install python-tk
based on:
https://matplotlib.org/3.1.1/faq/virtualenv_faq.html
I had to pip3 uninstall matplotlib twice since I apparently had 2 versions installed. Then reinstall it.

What is the issue here?
Okay,
so I still dont know, what was wrong in this, but I did solve the problem.
I simply uninstalled seaborn
pip3 uninstall seaborn
and installed it again
pip3 install seaborn
it worked, no error this time.
But I still dont know, what went wrong first time.
If someone can help please share.
The problem is that seaborn seems to be using a private method from pandas. The issue has been reported to both pandas and seaborn developers (see https://github.com/pandas-dev/pandas/issues/16971 and https://github.com/mwaskom/seaborn/pull/1241) which both published a fix in later versions.
The fixed version is available on pip but not on Ubuntu's packages yet (as of August 2020).
However, for those who don't want pip install, the fix is straightforward and can be manually applied (see the pull request above).
I am using a windows10 machine and using PyCharm as my IDE, so when I tried to run the below code, it shows the following error
I tried uninstalling and re-installing matplotlib and also as someone from SO suggested used --force reinstall too, but didn't work
It was working well until yesterday

I had a similar problem which was solved simply by forcing the reinstall of matplotlib:
python -m pip install -I matplotlib
The python -m pip instead of pip install to make sure the correct python executable is used
The -I forces reinstall
I believe i had a similar issue - https://github.com/matplotlib/jupyter-matplotlib/issues/155 - It could be that you are using python installed from a different source (appstore or from python.org?). I suspect the issue is that your kernel is using a different python than it was a few days ago.
try deleting the Python folder in:

and run again.
I am a beginner at programming and I am working on an online course which uses ipython and jupyter notebook. I am working with Mac OS 10.13.3.

import matplotlib.pyplot as plt
%matplotlib inline

This is because you are using old version of matplotlib.
Those who are using GraphLab Create, first activate virtual environment:
source gl-env/bin/activate
Now upgrade matplotlib:
pip install -U matplotlib
Output:
Found existing installation: matplotlib 1.5.1
Uninstalling matplotlib-1.5.1:
Successfully uninstalled matplotlib-1.5.1
Successfully installed matplotlib-2.1.2
Restart iPython/Jupyter.
If you are on Mac, you might get the following error:
RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework.
Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg
Again restart iPython/Jupyter.
I am using the Anaconda distribution for Windows 10 (Anaconda3 specifically), and I have a large variety of packages installed, relevant packages could be python 3.5.1, numpy 1.10.4, jupyter 1.0.0 (with the client, console, and core packages), matplotlib 1.5.1 (np110py35_0), notebook 4.1.0, and uncertainties 2.4.7.1.

ImportError: DLL load failed: The specified module could not be found.
This error occurred while I was working with some data in the jupyter notebook. Upon starting the notebook and importing the modules I needed, the notebook was running just fine. However, at one point the notebook I had been working on had been cluttered with variables, so I decided to restart the kernel via the command bar in the top part of the notebook and run it again (a very normal thing for me to do that I have done multiple times without problems.
It might be worth noting I was using numpy, matplotlib.pyplot, and the uncertainties package at the time. When I restarted the kernel though, I got that ImportError listed above.
Before starting the notebook, I used conda update --all (as I usually do), and everything was working normally. The problem occurred after I had restarted the kernel a few times.
The solutions I have tried and have had no success with are:
restarting the jupyter notebook and loading it again
creating a new, clean jupyter notebook (.ipynb file) and attempting to use import matplotlib.pyplot as plt again
trying to revert to a more stable version of anaconda by using conda update anaconda
I am wary when it comes to re-installing Anaconda by using conda install anaconda, or uninstalling and re-installing matplotlib. I am worried it might interfere with some of my other packages, so I wanted to see if there were other options first.
Any help would be appreciated, thank you!
I had the same problem and unfortunately only reinstalling Anaconda fixed it... For some reason I had to delete the Anaconda3 folder manually before reinstalling in order for it to work. (simply uninstalling anaconda does not delete the folder)
Hope that helps you out, best of luck.
I'm trying to use matplotlib on Ubuntu 12.04. So I built a wheel with pip:
python .local/bin/pip wheel --wheel-dir=wheel/ --build=build/ matplotlib
Then successfully installed it:
python .local/bin/pip install --user --no-index --find-links=wheel/ --build=build/ matplotlib
But when I'm trying to import it in ipython ImportError occures:
In [1]: import matplotlib
In [2]: matplotlib.get_backend()
Out[2]: u'agg'
In [3]: import matplotlib.pyplot

May be I'm doing somethig wrong? Or may be there is a way to turn off gui support of matplotlib?
Thanks in advance.
Okay, the problem was in gcc version. During building and creating wheel of package pip uses system gcc (which version is 4.7.2). I'm using python from virtualenv, which was built with gcc 4.4.3. So version of libstdc++ library is different in IPython and one that pip used.
As always there are two solutions (or even more): pass LD_PRELOAD environment variable with correct libstdc++ before entering IPython or to use same version of gcc during creating wheel and building virtualenv. I prefred the last one.
Thank you all.
