zachgk edited a comment on issue #12487: [Scala] PrefetchingIter fails with labels and predictions should have the same length URL: https://github.com/apache/incubator-mxnet/issues/12487#issuecomment-454120489 If you are interested, it should not be too difficult to create something like `AppendIter(iters: IndexedSeq[IndexedSeq[DataIter]])`. The [documentation](https://mxnet.incubator.apache.org/versions/master/api/scala/docs/index.html#org.apache.mxnet.DataIter) and the [SyntheticDataIter](https://github.com/apache/incubator-mxnet/blob/master/scala-package/examples/src/main/scala/org/apache/mxnetexamples/imclassification/datasets/SyntheticDataIter.scala) might be good references and it would be a great [contribution](https://mxnet.apache.org/community/contribute.html). @mxnet-label-bot add [Call for Contribution, Good First Issue, Feature]
