Hello,

Currently I'm trying to call Python code from Matlab (using R2019b), nevertheless when I try amy python code I have the followin error:

>> P = py.sys.path
Unable to resolve the name py.sys.path.
>> py.print
Unable to resolve the name py.print.

Matlab cannot find or load any Python code, according to pyenv the instalation from Python is correct:

>> pyenv
ans = 
  PythonEnvironment with properties:
          Version: "3.7"
       Executable: "C:\Users\alis\AppData\Local\Programs\Python\Python37\python.exe"
          Library: "C:\Users\alis\AppData\Local\Programs\Python\Python37\python37.dll"
             Home: "C:\Users\alis\AppData\Local\Programs\Python\Python37"
           Status: NotLoaded
    ExecutionMode: InProcess
    

How can I load Python corretly to execute Python libraries and functions from Matlab?

It seems that Python is not loaded, I can't really tell how to do load it, maybe these functions are not correctly called. See this video for basics https://www.mathworks.com/videos/using-matlab-with-python-1591216182793.html

THanks, I already saw this video, nevertheless it seems like it was a version issue, I have change the Python version to be 3.7.9 and now Matlab can call Python and execute correctly.
