Summary: This is a modified version of https://github.com/pytorch/pytorch/pull/14705 since commit structure for that PR is quite messy. 1. Add `IterableDataset`. 3. So we have 2 data loader mods: `Iterable` and `Map`. 1. `Iterable` if the `dataset` is an instance of `IterableDataset` 2. `Map` o.w. 3. Add better support for non-batch loading (i.e., `batch_size=None` and `batch_sampler=None`). This is useful in doing things like bulk loading. 3. Refactor `DataLoaderIter` into two classes, `_SingleProcessDataLoaderIter` and `_MultiProcessingDataLoaderIter`. Rename some methods to be more generic, e.g., `get_batch` -> `get_data`. 4. Add `torch.utils.data.get_worker_info` which returns worker information in a worker proc (e.g., worker id, dataset obj copy, etc.) and can be used in `IterableDataset.__iter__` and `worker_init_fn` to do per-worker configuration. 5. Add `ChainDataset`, which is the analog of `ConcatDataset` for `IterableDataset`. 7. Import torch.utils.data in `torch/__init__.py` 9. data loader examples and documentations 10. Use `get_worker_info` to detect whether we are in a worker process in `default_collate` Closes https://github.com/pytorch/pytorch/issues/17909, https://github.com/pytorch/pytorch/issues/18096, https://github.com/pytorch/pytorch/issues/19946, and some of https://github.com/pytorch/pytorch/issues/13023 Pull Request resolved: https://github.com/pytorch/pytorch/pull/19228 Reviewed By: bddppq Differential Revision: D15058152 fbshipit-source-id: 9e081a901a071d7e4502b88054a34b450ab5ddde |
