I am getting "Swing is not available error"

I am trying to import a model. But when using importONNXNetwork function I am getting the following error:

Error using matlab.internal.indentcodeLegacy
This feature is not supported because:
Swing is not currently available.

Can anybody help me ?

Hi Gourav,

This is an bug with "importONNXNetwork" function. As a workaround, you can follow the below steps:

       1.   Run MATLAB desktop using the GUI.

       2.   Edit a file to remove the call to “indentcode” in MATLAB using the following command in MATLAB command window:    

>>edit nnet.internal.cnn.onnx.fcn.ModelTranslation

  Search for the call to “indentcode” and remove or comment out the line in the code containing the function call.

code = nnet.internal.cnn.onnx.util.indentcode(code);

       3.   Edit another file to remove the call to “indentcode” in MATLAB using the following command in MATLAB command window:   

>>edit nnet.internal.cnn.onnx.CustomLayerManager

  Search for “indentcode” and make the following change: 

Original code:

classdefCode = string(indentcode(char(join(classdefCode'newline))))

Modified code:

classdefCode = string(char(join(classdefCode',newline));

       4.   Write an identity function in your local directory to override the “indentcode” function.    

function X = indentcode(X)
end

Note - This issue was solved in MATLAB R2024a version.
