Error using trainNetwork (line 170)

Hello!

I am doing semantic segmentation of RGB images to 3 label classes using vgg-16 (for now). Matlab version 2020a.

When I pass the pixel Label Image Datastore to the trainNetwork function I get the following error:

[net, info] = trainNetwork(pximds,lgraph,options);

Error using trainNetwork (line 170)

Too many input arguments.

Caused by:

Error using gather

Too many input arguments.

Upon further inspection the error originates on line 194, iside the doTrainNetwork function:

trainedNet = assembler.assemble(analyzedLayers, executionSettings);

which itself fails inside the TrainingNetworkAssembler at line 33:

 internalNetwork = this.Strategy.prepareNetworkForTraining(...
                internalNetwork, executionSettings);
            
            

It seems the issue is with the network, not the inputs?

Any help would be welcome!

Has this problem been solved?
