I want to use Python's matplotlib in Matlab but I can't make even this simple example
close; clear; clc;
x = py.numpy.arange(25);
y = py.numpy.square(x) + py.numpy.random.rand(int32(25));
py.matplotlib.pyplot.plot(x, y);
work as Matlab crashes after showing with the following dialog:
I'm afraid that I don't know how to proceed after reading this message. (Admittedly, I haven't tried reinstalling Matlab but I suspect that won't help.) After pressing OK, then Matlab closes with this dialog:
I'm on a Windows 10 machine and using 64-bit Anaconda Python 3.7.6 and have started Matlab from the Anaconda prompt.
Below is the report:

MATLAB does not supports Anaconda Python, it supports the reference implementation of Python, often called CPython, versions 2.7, 3.6, and 3.7. To learn about installation refer to this link: Install Supported Python Implementation.
For the issue being faced you can refer to this answer: https://www.mathworks.com/matlabcentral/answers/427187-problem-with-python-numpy. However, it is recommended to use the supported implementation of Python.
