Unrecognized method, property, or field 'list' for class 'matlab.py​client.Pyt​honEnviron​ment'.

Hello,

I'm trying to run Python from Matlab and I'm finding some problems.

First of all I execute:

py = pyenv('Version','C:\Users\AppData\Local\Programs\Python\Python38\python.exe')

And the answer I'm getting is:

py =

PythonEnvironment with properties:

Version: "3.8"

Executable: "C:\Users\AppData\Local\Programs\Python\Python38\python.exe"

Library: "C:\Users\AppData\Local\Programs\Python\Python38\python38.dll"

Home: "C:\Users\AppData\Local\Programs\Python\Python38"

Status: NotLoaded

ExecutionMode: InProcess

After this, I'm trying to create a list with the next command:

py.list({'This','is a','list'})

And I'm getting the next error:

Unrecognized method, property, or field 'list' for class 'matlab.pyclient.PythonEnvironment'.

This happens every time that I try to execute py.something. I'm using Matlab 2020b version.

Could anyone help me out?

Thank you in advance!

Hello Irati,

Why do you call this?

py = pyenv('Version','C:\Users\AppData\Local\Programs\Python\Python38\python.exe')

According to this document (https://www.mathworks.com/help/matlab/ref/pyenv.html), it should be

pe = pyenv('Version','C:\Users\AppData\Local\Programs\Python\Python38\python.exe')

Here py is overwritten by mistake.

Thanks,

Yongjian
