I am currently working on several CNNs for regression. After several iterations (btw 1500-3000 something) of training a similar architecture as V-net by Miletari et.al and a less deep multi-input CNN architecture the training stops due to the error below.
Error using trainNetwork
Dimensions of arrays being concatenated are not consistent.
Error in net
[net,info] = trainNetwork(ds,lgraph,options);
Error using cat
Dimensions of arrays being concatenated are not consistent
shows no warnings or errors.
Did anyone experience the same issue and could tackle the reason for the issue?
