17.08.2017 · Summary: Add an optional ```timeout``` argument to ```EpochBatchIterator```. I need it to fix this issue: pytorch/pytorch#2474 I could do something more general, allowing one to pass ```**dataloader_kwargs``` to ```torch.utils.data.DataLoader```, if you think it's worth.

21.09.2021 · Hi, everyone When I train my model with DDP, I observe that my training process got stuck every few seconds. The device information is shown in the following figure when it is stuck. There seems always one GPU got stuck whose utilization is 0%, and the others are waiting for it to synchronizing. This issue disappears after switching to another server (with the same image). …

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.
torch.utils.data. At the heart of PyTorch data loading utility is the torch.utils.data.DataLoader class. It represents a Python iterable over a dataset, with support for. map-style and iterable-style datasets, customizing data loading order, automatic batching, single- and multi-process data loading, automatic memory pinning.
