I am trying to call MATLAB from python.
I have python 3.9.13 and matlab 9.11.0.1769968 (R2021b).
I installed the matlab engine for python by running the following commands in matlab:
cd (fullfile(matlabroot,'extern','engines','python'))
system('python setup.py install')
I then ran the python commands:
>>> import matlab.engine
>>> eng = matlab.engine.start_matlab()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\__init__.py", line 130, in start_matlab
eng = future.result()
File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\futureresult.py", line 67, in result
return self.__future.result(timeout)
File "MY_USER_FOLDER\AppData\Local\Programs\Python\Python39\lib\site-packages\matlab\engine\matlabfuture.py", line 87, in result
handle = pythonengine.getMATLAB(self._future)
matlab.engine.EngineError: Unable to launch Simple server: Unable to launch C:\Program Files\MATLAB\R2021b\bin\win64\MATLAB.exe
because: Timed out reading transport byte from transport
And the matlab error:
Fatal Startup Error
Dynamic exception type: class
foundation::catapult::carrier::stream::TranspodException
std::exception::what: Unable to conned to parent because:
GetHandleInformation failed: 6

Try installing using the "python -m pip install ." command instead.
There is more information on the MATLAB Engine installation page here:
