Why do I receive a "subproces​s-exited-w​ith-error" error message when installing "matlabengine"?

Does someone have a fix for this?

Hi,

far down the error stack, it tells the underlying problem:

This release of MATLAB Engine API for Python is compatible with version 9.15. The found versions were 9.14.

Best wishes,

Harald

MATLAB Engine API for Python is returning an error because the command you are using to download it does not specify a download version.

You are currently using the command, “pip install matlabengine”, which installs the version of Python Engine API that is compatible with the latest MATLAB release. This means that if you are not using the latest release of MATLAB, you will need to specify the version of Python Engine API that is compatible with your release.

For example, if you are using MATLAB R2023a, you would first need to determine what version of Python Engine API is compatible with MATLAB R2023a. You can do this by visiting the following link and reading the “Required MathWorks Products” section for each release.

https://pypi.org/project/matlabengine/#history   

The newest release of MATLAB Engine API for Python that is compatible with MATLAB R2023a is 9.14.7. To install MATLAB Engine API for Python version 9.14.7, run the following command.

python -m pip install matlabengine==9.14.7

You can find more information about MATLAB Engine API for Python version 9.14.7 at the following link.
