I have a List on which I’m trying to call MultiDataSet.merge. Each MDS in the list contains one example with 2 feature arrays and 3 label arrays; the feature arrays are respectively 3-dimensional (9x9x19) and 1-dimensional (11 “global” variables); the label arrays are 3-d, scalar, and scalar.
I get an exception at org.nd4j.linalg.dataset.api.DataSetUtil.mergeFeatures(DataSetUtil.java:211), which expects arrays of 2 to 4 dimensions only.
Why not 1-dimensional arrays? Am I missing a concept?
(So far I’ve just been preparing my data, and I haven’t started specifying my ComputationGraph yet.)
