Steps to reproduce:
[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]
- Run the code:
%matplotlib inline
from matplotlib import pyplot as plt
img = plt.imread('../data/image/CLAHE_before.jpg')
print("==>> type(img): ", type(img)) # success here
print("==>> img.shape: ", img.shape) # success here
plt.imshow(img) # error occur here

Closing so that we can handle this better and provide a more contextual error message, see here https://github.com/microsoft/vscode-jupyter/issues/9375
This error code stands for ‘external exception’ as far as I know. This generally means some part of the app called into another dll that caused a crash/exit. Without debugging the call that caused the problem, it’s really hard to tell why.
