ModuleNotFoundError: No module named 'matplotlib.pyplot'

Question

When making a plot, I used both Jupyter Notebook and Pycharm with the same set of code and packages. The code is:

import pandas as pd
import numpy as np 
import matplotlib.pyplot as plt   # as in Pycharm
import matplotlib as plt          # as in Jupyter

df = pd.read_csv("/home/kunal/Downloads/Loan_Prediction/train.csv")
df['ApplicantIncome'].hist(bins=50)
plt.show() #this only in Pycharm not in Jupyter.

In Pycharm, the code works well. But in Jupyter Notebook, it has error:

I wish someone can help me solve this problem

Answer 1

This is an indication that matplotlib lib/module is not installed. So all you have to do is install this module by running the code below in the cell previous to referring matplotlib:

!pip install matplotlib

Hope it helps!

Answer 2

I had the same problem and found a solution! Matplotlib was installed on another python installation I have.

Put the following snippet in a cell and execute it, and you should be good to go:

import sys
!{sys.executable} -m pip install matplotlib

Answer 3

You don't need to use %matplotlib inline as other answers here suggest. This is optional and not using it should not prevent importing pyplot.

What should work is the following:

You may decide to use %matplotlib inline in which case you don't have to call plt.show() .

You may also use %matplotlib notebook , which gives you an interactive plot.

Finally, you may use %matplotlib tk to get a windowed figure like you would in PyCharm.

All of those options require to have imported matplotlib.pyplot . Importing matplotlib alone is not helpful. Also, if you experience any problems, start a new kernel first (don't try something new in line 27 of your notebook).

Answer 4

if you are using jupyter notebook in anaconda, matplotlib should be installed to the environment.

go to Environments -> the environment you are using -> change the droplist to not installed -> search matplotlib, and install

Answer 5

if you are using Anaconda CMD the use this command,

conda install matplotlib 

If you are using Normal CMD then use command,

pip install matplotlib

or

pip3 install matplotlib

Answer 6

在代码顶部%matplotlib inline添加%matplotlib inline ，它使 matplotlib 以交互方式执行

Answer 7

这段代码对我有用

%pip install matplotlib-inline
