How to call python Script in specified environment in Matlab?

11 次查看(过去 30 天)
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/"
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/',
I want to call python script like this:
>> !python
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?

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
