19.04.2018 · It is used e.g. by the DataLoader to know, how many samples are available in the Dataset. Until now we didn’t have to think about batching, i.e. in other frameworks we would have to implement something like a for-loop in a generator and load batches of samples. Also, we didn’t have to think about shuffling etc. The Dataset would look like this:

Iterable-style datasets An 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.

Dec 21, 2021 · Hello there, I want to make custom dataset or dataloader, just don’t know which is the best way to do it. This is a self supervised task, where you want to blank out part of the input and then use it as a “label”. Let’s say I have .npy files, each one of shape (600,30000), and I want to do the following: Read the file, pick a row from the 600, take a slice around that row, say (32 ...

Sep 19, 2019 · Hello, Im trying to set up a processes to deal with streaming sensor data. I understand this is the exact usecase for iterable datasets. Unfortunately it seems to be a relatively new feature and tutorials on how to make and use iterable datasets appear to be rare. To start I am mocking by making my iter function grab from a CSV. I am not sure exactly what my iter function should be returning ...

PyTorch provides two data primitives: torch.utils.data.DataLoader and torch.utils.data.Dataset that allow you to use pre-loaded datasets as well as your own data. Dataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.
