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
