Datasets should not be an empty iterable
WebAn iterable-style dataset is an instance of a subclass of IterableDataset that implements the __iter__() protocol, and represents an iterable over data samples. This type of datasets is particularly suitable for cases where random reads are expensive or even improbable, and where the batch size depends on the fetched data.

WebCreating and Reading Empty (or Null) datasets and attributes¶ HDF5 has the concept of Empty or Null datasets and attributes. These are not the same as an array with a shape of (), or a scalar dataspace in HDF5 terms. Instead, it is a dataset with an associated type, no data, and no shape.

This was considered "a fairly harmless quirk" until it was documented in 3.5. Then assigning to an empty tuple () was added for consistency. In the same thread, Martin Panter provides a possible use case: [...]

To answer the first-- the sequence model is not strictly necessary, because the feature extractor is trained to predict behaviors-- that's what you're seeing.
