I try to follow the Matlab instruction on connection from python to a running matlab session.

In matlab

matlab.engine.shareEngine

runs without errors.

Than from virtuall enviroment with matlab installed

import matlab.engine

eng = matlab.engine.connect_matlab()

but that results in the error:

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "..\.venv\lib\site-packages\matlab\engine\__init__.py", line 188, in connect_matlab

eng = future.result()

File "..\.venv\lib\site-packages\matlab\engine\futureresult.py", line 67, in result

return self.__future.result(timeout)

File "..\.venv\lib\site-packages\matlab\engine\matlabfuture.py", line 87, in result

handle = pythonengine.getMATLAB(self._future)

matlab.engine.EngineError: System error: Failed to get current user groups

Staring the engine from within python

eng = matlab.engine.start_matlab

works fine.

I am useing a windows 11 system.

From the error message it sounds like a permission issue or a windows/matlab interaction problem. But I have not be able to validate any of that.I would happily take points on what might cause the problem.

HI Swastik,

Thanks for your response.

I did read the username from both, python and matlab and the answer is matching.

Than I followed your link, and learned that I can use pip to install the python packages. Before I used the setup from within the matlab installation. So I created an empty enviroment and install from pip. Than I opend a python console in that enviroment and tried to connect to matlab, but got the same error.

Best
