Hi everyone! I trying to run [deeplearning4j-examples/Conv1DUCISequenceClassification.java at master · deeplearning4j/deeplearning4j-examples · GitHub](https://github.com/deeplearning4j/deeplearning4j-examples/blob/master/dl4j-examples/src/main/java/org/deeplearning4j/examples/quickstart/modeling/convolution/Conv1DUCISequenceClassification.java) ‘as is’ (and with latest version of dl4j) and got an error: `Invalid mask array: per-example masking should be a column vector, per output masking arrays should be the same shape as the output/labels arrays. Mask shape: [10, 60], output shape: [580, 6](layer name: layer1, layer index: 1, layer type: OutputLayer)`. What am I do wrong?
