I was trying to replicate the example in Semantic Segmentation Using Deep Learning
Error using matlab.io.datastore.PixelLabelDatastore.label2cat (line 1030)
Pixel label image has RGB-triplet pixel label IDs instead of scalar pixel label IDs.
At first I got it at
pximds = pixelLabelImageDatastore(imdsTrain,pxdsTrain, ...
But then I didn't include the augmenter and there was no problem there. Afterwards, the same again in:
[net, info] = trainNetwork(pximds,lgraph,options);
I searched it in google, it seems other people also had the same, but there was no answer to it. It's just the example proposed in mathworks
