Creating a PyTorch Dataset and managing it with Dataloader keeps your data manageable and helps to simplify your machine learning pipeline.

The DataLoader supports both map-style and iterable-style datasets with single- or multi-process loading, customizing loading order and optional automatic batching (collation) and memory pinning. See torch.utils.data documentation page for more details. Parameters dataset ( Dataset) – dataset from which to load the data.

24.02.2021 · Dataloader has been used to parallelize the data loading as this boosts up the speed and saves memory. The dataloader constructor resides in the torch.utils.data package. It has various parameters among which the only mandatory argument to be passed is the dataset that has to be loaded, and the rest all are optional arguments. Attention geek!

... to create and use PyTorch Dataset and DataLoader objects, used to serve up training or test data in order to train a PyTorch neural network.

DataLoader provides a memoization cache for all loads which occur in a single request to your application. After .load () is called once with a given key, the resulting value is cached to eliminate redundant loads. Caching Per-Request DataLoader caching does not replace Redis, Memcache, or any other shared application-level cache.
