In ConvolutionUtils, the numFeatureMaps methods pulls from the second position in filterSize (e.g. where channels are set) vs the first position of the list. \r\n\r\nhttps://github.com/deeplearning4j/deeplearning4j/blob/master/deeplearning4j-core/src/main/java/org/deeplearning4j/util/ConvolutionUtils.java#L78\r\n\r\nIn ConvolutionLayer, this line appears to set the featureMaps number:  https://github.com/deeplearning4j/deeplearning4j/blob/master/deeplearning4j-core/src/main/java/org/deeplearning4j/nn/layers/convolution/ConvolutionLayer.java#L113\r\n\r\nThe line after it looks like its setting channels.
