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 Jupyterdf = 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

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
