Getting this error in matlab coder, Function 'imageInputLayer' not supported for code generation.

So used coder.extrinsic('imageInputLayer') in code. But for this also getting error as below.

The extrinsic function 'imageInputLayer' is not available for standalone code generation. It must be eliminated for stand-alone code to be generated. It could not be eliminated because its outputs appear to influence the calling function. Fix this error by not using 'imageInputLayer' or by ensuring that its outputs are unused.

How to resolve this issue??

Walter is correct, codegen is not supported for DL training workflows, but is supported for DL inference workflows.

Are you trying to generate code for a function that trains a DL network? Could you elaborate more on your workflow and overall goal?

You can not fix it. That function is used for training networks, but code generation is not supported for training networks.

Code generation is supported for loading an already trained network and using it to predict or classify.
