Hello,
I'm trying to call python from matlab but I'm getting the message:
py.list({'Monday','Tuesday','Wednesday','Thursday','Friday'})
Unable to resolve the name py.list.
For all code I type with py. this happens.
I also have tried pyenv, and I got:
>> pyenv
ans =
PythonEnvironment with properties:
Version: "3.7"
Executable: "C:\Users\Familia\.conda\envs\matlab\python.exe"
Library: "C:\Users\Familia\.conda\envs\matlab\python37.dll"
Home: "C:\Users\Familia\.conda\envs\matlab"
Status: NotLoaded
ExecutionMode: InProcess
Maybe the problem is the status? NotLoaded? How do I change that for loaded?
I also have tried to modify the path for another python I have installed, not from Anaconda with this command
pe = pyenv('Version','C:\Users\Familia\AppData\Local\Microsoft\WindowsApps\python.exe')
But then, I got this error:
Error using pyenv
Path argument does not specify a valid executable.
I really need to run python in matlab and I don't know what to do

I don't even get any useful response when I run "pyenv" in MATLAB 2022a, even though I have donwloaded Python 3.9.13. After downloading Python, what else has to be done to get MATLAB to "talk" to it?

- Check if your python executable path is correct?
- Set the python environment with correct python executalbe first it will show the status as "NotLoaded", run any "py" command, check the status it will show status ass "Loaded".
And there is an alternate way to use python scripts and functions from matlab, using "system()" function as,
system('python <script> <arguments>')
For example,
system('python /Users/myName/pathToScript/sqr.py 2')
