ImportError: No module named matplotlib.pyplot in Python

Dung Do Tien Dec 06 2021 17

Hello Guys, I'm just studying Python one month before and I practiced with matplotlib with basic simple like this

 import matplotlib.pyplot as pylot

lst_radius = [1.0, 1.2, 1.4, 1.6, 1.8, 2.0]
pointer = [1.9434, 4.8773, 8.2545, 9.9882, 11.9822, 54.0993 ]

pylot.plot(lst_radius, pointer)
pylot.show()

But when running this code I got an exception ImportError: No module named matplotlib.pyplot.

 Traceback (most recent call last):
File "./radius_pyplot_lib.py", line 1, in <module>
  import matplotlib.pyplot as pylot
ImportError: No module named matplotlib.pyplot

I'm using Python 3.8.2 and running on window 10.

Do you have any suggestions for me?

Thank you so much.

    You can run the command below to install matplotlib package in Python 3:

      python3 -m pip install matplotlib --user

    And it's worked for me!

    You need to install matplotlib, by using the command below:

    Python2:

     sudo apt-get install python-matplotlib

    Python3:

     sudo apt-get install python3-matplotlib

    It really works for me.

    You are using Python 3, you can use pip3 to install matplotlib package:

     sudo pip3 install matplotlib 

    Or

     sudo apt-get install python3-matplotlib
