cannot import name 'ft2font' from 'matplotlib' on windows10

Question

I am using a windows10 machine and using PyCharm as my IDE, so when I tried to run the below code, it shows the following error

I tried uninstalling and re-installing matplotlib and also as someone from SO suggested used --force reinstall too, but didn't work

It was working well until yesterday

import matplotlib.pyplot as plt
import numpy as np

 rng = np.random.RandomState(42)
 X = 10 * rng.rand(50)
 y = 2 * X - 1 + rng.randn(50)

plt.scatter(X, y)
plt.show()

Error showing on both Pycharm and Vs Code

I had a similar problem which was solved simply by forcing the reinstall of matplotlib:

python -m pip install -I matplotlib

The python -m pip instead of pip install to make sure the correct python executable is used
The -I forces reinstall

I believe i had a similar issue - https://github.com/matplotlib/jupyter-matplotlib/issues/155 - It could be that you are using python installed from a different source (appstore or from python.org?). I suspect the issue is that your kernel is using a different python than it was a few days ago.

try deleting the Python folder in: Users\smile\AppData\Roaming\Python\Python37\site-packages\matplotlib__init__.py) and run again.
