Hi,

I went through the example "Semantic Segmentation of Multispectral Images Using Deep Learning." I'd like to restart training to improve the network I trained and, according to MATLAB's help, one needs to provide the net.Layers data to trainNetwork.

The command I used to restart training is

[net,info] = trainNetwork(dsTrain,net.Layers,options);

Launching the code I get the following error:

Error using trainNetwork
Invalid network.
Error in Deep_Learning_Testing (line 2357)
[net,info] = trainNetwork(dsTrain,net.Layers,options);
Caused by:
Layer 'Decoder-Section-1-DepthConcatenation': Unconnected input. Each layer input must be connected to the output of another layer.
Layer 'Decoder-Section-2-DepthConcatenation': Unconnected input. Each layer input must be connected to the output of another layer.
Layer 'Decoder-Section-3-DepthConcatenation': Unconnected input. Each layer input must be connected to the output of another layer.
Layer 'Decoder-Section-4-DepthConcatenation': Unconnected input. Each layer input must be connected to the output of another layer.
