Matlab Python Engine on MacOs

I am trying to install the Matlab Python API on a MacOS Monterey 12.0.1 machine.
After I performed the "python3 setup.py install" command, which executes correctly, the package is in the correct site-package folder. When I start a session with "python3" and try to "import matlab.engine", I get the following error message:
>>> import matlab.engine
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/homebrew/lib/python3.9/site-packages/matlab/engine/__init__.py", line 77, in <module>
raise EnvironmentError(secondExceptionMessage)
OSError: Please reinstall MATLAB Engine for Python or contact MathWorks Technical Support for assistance:
First issue: No module named 'matlabengineforpython3_9'
Second issue: dlopen(/Applications/MATLAB_R2021b.app/extern/engines/python/dist/matlab/engine/maci64/matlabengineforpython3_9.so, 0x0002): tried: '/Applications/MATLAB_R2021b.app/extern/engines/python/dist/matlab/engine/maci64/matlabengineforpython3_9.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e')), '/usr/local/lib/matlabengineforpython3_9.so' (no such file), '/usr/lib/matlabengineforpython3_9.so' (no such file)
How can I solve this?
Thank you in advance!

Hi,
According to my understanding, to resolve this issue please install the maci64 version of Python and use that with (maci64) MATLAB.
You should download one of the "Intel-only" installers on this page (https://www.python.org/downloads/macos/) to get "maci" versions of Python.

Hello Anshika,
I have tried the "Intel-only" python version, but I still have the same error as dmhd. Could you please help me?
