This handling will be related to the python version you are apply. If it’s python 2.x and also linux version, run the following line:

sudo apt-get install python-matplotlib

Solution 3: Apply the command below

Same as for the 2nd method, but if the version you have is Python 3.x, apply the command below:

sudo apt-get install python3-matplotlib

Solution 4: For user apply Anaconda3

Another workaround for user apply Anaconda3. This way is also very simple, please run the command below to handle the error:

conda install -c conda-forge matplotlib

Solution 5: Run this command line

For this way, your first step is to run this command line:

python3 -m pip install matplotlib

and continue to enter this line and your error is solved:

import matplotlib.pyplot as plt

Solution 6: Reinstall matplotlib

If all of the above methods you have applied but the error is still not resolved, try reinstalling matplotlib. Firstly, uninstall the version you are using using the command:

pip uninstall matplotlib

Next set up with the version you want, for example:

with python 3:

python3 -m pip install matplotlib

with python 2:

python2 -m pip install matplotlib

Solution 7: Follow the guide below

Excepting the solutions mentioned above, there is another solution for you to fix the error “ImportError: No module named matplotlib.pyplot”. Let’s follow the guide below:

You have two versions of Python installed on your computer: the default one that ships with Mac OS X and the one you set uo by using ports (this is the one that has matplotlib set up in its library, the one that comes with macosx doesn’t).

/usr/bin/python

It is the default Python for Mac, and as it lacks Matplotlib, you should always start your script using the one that is installed by using ports.

If your script in Python runs successfully, let’s replace the #! with:

#!/usr/bin/env python

Alternately, you can enter the complete path to the Python interpreter’s library where the matplotlib package is installed. 

After doing that, your error will completely disappear and your program will run well without any errors. So, what are you waiting without applying it to get you desired results?
