Problem with Conv1D example

Hi everyone! I trying to run deeplearning4j-examples/Conv1DUCISequenceClassification.java at master · deeplearning4j/deeplearning4j-examples · GitHub ‘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?
