I installed matplot.lib by using the command sudo apt-get install python3-matplotlib.



While running a program written in python it is showing



Traceback (most recent call last):
File "example.py", line 6, in <module>
import matplotlib.pyplot as plt
ImportError: No module named matplotlib.pyplot


What is the problem and how do I install matplotlib properly?



I am trying to run a program that calculates refractive index and the link is https://github.com/polyanskiy/refractiveindex.info-scripts

    Welcome to Ask Ubuntu! Could you please edit question to add a few details for clarification? What's the program? How did you install the Python interpreter in question and the mathplotlib module? Thanks.

  • @AtrayeeHazra It depends on how you installed Python. Tell us how you installed Python and what the output of which python or which python3 is.
