How to call python script contains "pytorch" module normally

I want to call a python script, which uses the pytorch module, in matlab script, but then it occures error:

Traceback (most recent call last):
File "/home/usrs/xxxxx/xxxxxx/test.py", line 9, in <module>
import torch
ModuleNotFoundError: No module named 'torch'

I have checked pyversion and pyenv and I can use other module (e.g. numpy), but I can't clear this error.

I know I can use pytorch model in MATLAB by converting from pytorch model to ONNX model.

However, I want to run this python script because it's easier than converting.

In addition, I checked this answer, but I can't understand well. So I hope help.

Thank you so much!

Append the path to torch to an env var called PYTHONPATH. Do this from matlab command line window:

setenv('PYTHONPATH', [getenv('PYTHONPATH') ';C:\the_path_to_torch']);

I have imported pytorch by this method! Thank you so much!

I am also facing this error when I run a python script which imports torch using the MATLAB function pyrunfile()

Error using __init__><module> (line 135)

Python Error: OSError: [WinError 126] The specified module could not be found. Error loading

"C:\Users\Navid\.conda\envs\RL37\lib\site-packages\torch\lib\caffe2_detectron_ops_gpu.dll" or one of its dependencies.
