Deep Network Designer, Faster R-CNN

Hello

Can anyone please help me with resolving this error message?

The error message occurs after uploading the network to the deep network designer application

Thank you

Deep Network Designer currently doesn't support training of a network with multiple outputs.

To train Faster R-CNN, you could use the trainFasterRCNNObjectDetector function as shown in this example.
