I'm using MATLAB 2019b, Python 3.7.9 on Windows 10. In my python code, I have the below lines
import matlab
import matlab.engine
mat_eng = matlab.engine.start_matlab()
print(mat_eng.license('test','Signal_Toolbox'))
This always prints 1. However, when I try to access a signal processing toolbox function like resample, I see a license checkout error as below:
License checkout failed.
License Manager Error 0
Troubleshoot this issue by visiting:

Diagnostic Information:
Feature: Signal_Toolbox

I'm able to use the resampler from MATLB directly. How do I solve this error?
