I am trying to luch the python file using the pyrunfile, but got an error.
Verificatio of the python version all shows me the answer (see below), nevertheless that in comandn line i see Version 3.8.3:
What is the problem?
Thanks in advance
In Matlab:
>> pyversion
version: ''
executable: ''
library: ''
home: ''
isloaded: 0
C:\Users\Sarr>python --version
Python 3.8.3

matlab uses PATH env var to find python. Your python installation is in a local path. Try this in matlab command line:
If the path to your python is not there, then set the PATH env var in matlab command line
setenv('PATH', new_path_with_python_location_added)

Sean suggested that you might need to check if you have installed a 32bit python. Start python from Windows command line like this. Your path shown above really looks like a 32bit. If so, you need to install a 64bit python to make it work.

It might be the case that you are using a Matlab version that does not support python 3.8.
Kindly double check the supported python versions for your matlab version here: https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/python-compatibility.pdf

Thnaks for the answer. The version I have 2021b has to work with python 3.8 (according to support info)

Looks like you have 32-bit python. You need 64-bit Python.

Have you tried installing Python not locally for your user, but for all users?
I have the same problem and wanted to try that now. Unfortunately I then no longer have my current environments.
