Error using trainNetwork (line 165)
Invalid training data. The output size ([512 512 3]) of the last layer does not match the response size ([256 256 3]).
Error in dice_try_data (line 35)
net = trainNetwork(ds,layers,options);

The error message seems clear to me, your neural net expects 256x256 image but is getting 512x512 images.
I know nothing about the neural net toolbox so can't help any further.
