nswamy commented on issue #11790: NPE in BucketingModule when providedLabel of DataBatch is not set URL: https://github.com/apache/incubator-mxnet/pull/11790#issuecomment-405811157 @milandesai Thanks for the quick fix, @lanking520 also suggested the same fix. This will work for now, we are discussing to add new APIs(alike provideData and provideShape) to take `Option[IndexedSeq[DataDesc]]` in `DataIter` and remove the `implicit def ListMap2Descs`, it is also causing other problems, for example not considering the layout of the input. For RNN it is required to know whether it is the `NTC` or `TNC` format. I'll keep you posted once we have a proper solution in place aswell.
