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.

The Dataset class has three important class functions: __init__ (): as usual, the starting point where we will initialize everything that we use in the class. __len__ (): this returns the length of the dataset. PyTorch supports two different types of datasets: map-style datasets, iterable-style datasets. Map-style datasets A map-style dataset is one that implements the __getitem__ () and __len__ () protocols, and represents a map from (possibly non-integral) indices/keys to data samples. deck support blocks at lowe\u0027s
