How to call python Script in specified environment in Matlab?

I want to call a python script in matlab script.

I want to call a python script in miniconda 'test' environment, but I can't do this.

This is because it happens version missmatch like this.:

>> pyenv

ans = 

  PythonEnvironment with properties:

          Version: "3.7"
       Executable: "/home/usrs/xxxxxx/miniconda3/envs/test/bin/python"
          Library: "/home/usrs/xxxxxx/miniconda3/envs/test/lib/libpython3.7m.so"
             Home: "/home/usrs/xxxxxx/miniconda3/envs/test"
           Status: NotLoaded
    ExecutionMode: OutOfProcess
    
>> !python
Python 3.8.3 (default, May 19 2020, 18:47:26) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/home/usrs/xxxxxx/miniconda3/lib/python38.zip', 
     '/home/usrs/xxxxxx/miniconda3/lib/python3.8', 
     '/home/usrs/xxxxxx/miniconda3/lib/python3.8/lib-dynload', 
     '/home/usrs/xxxxxx/miniconda3/lib/python3.8/site-packages']

I want to call python script like this:

>> !python test.py

I want to use python 3.7 and 'test' environment, but matlab has called python 3.8.3 and 'base' environment.

What should I do for this problem?

Thanks.

Hi,

please see this answer by Walter. I think pyenv() affects only python calls using the py.-prefix. But calling python via system() (or !) uses the python interpreter registered in the systems PATH variable.

Best, Konrad
