RuntimeError: No compatible MATLAB installation found in Windows Registry. This release of MATLAB Engine API for Python is compatible with version 9.15. The found versions were 9.14.

[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.

ERROR: Failed building wheel for matlabengine

Failed to build matlabengine

ERROR: Could not build wheels for matlabengine, which is required to install pyproject.toml-based projects

maybe someone have 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

Hi @Timur,

It is likely you are facing this error because the version of MATLAB you are using is not compatible with the version of "matlabengine" you are trying to install.

Since the stack mentions that version 9.14 is available, I am assuming you are currently working with MATLAB 2023a. The "matlabengine" release you are trying to install is version 19.5 which requires MATLAB 2023b.

To install the 9.14 version, you can run the command below:

pip install matlabengine==9.14.2 

You can visit this link for more information about the releases and the corresponding versions of MATLAB they require:

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

Additionally, you can look at the requirements for 9.15 version by accessing this link: https://pypi.org/project/matlabengine/9.15.2/#:~:text=from%20Python%20code.-,Requirements,-Required%20MathWorks%20Products

Please refer to the following documentation for more information about installing "matlabengine” API for Python:

• https://www.mathworks.com/help/matlab/matlab_external/install-the-matlab-engine-for-python.html
• https://pypi.org/project/matlabengine/

Hope this resolves your issue!
