- class cerebras.modelzoo.data.common.config.HDF5IterableDataProcessorConfig(batch_size: int = <object object at 0x7f2933a50b80>, shuffle: bool = True, shuffle_seed: int = 0, num_workers: int = 0, prefetch_factor: int = 10, persistent_workers: int = True, shuffle_buffer: Optional[int] = None, drop_last: bool = True)[source]#
- shuffle_buffer: Optional[int] = None#
Size of shuffle buffer in samples.
- drop_last: bool = True#
similar to the PyTorch drop_last setting except that samples that when set to True, samples that would have been dropped at the end of one epoch are yielded at the start of the next epoch so that there is no data loss. This is necessary for a data ordering that is independent of the distributed setup being used.
- prefetch_factor: int = 10#
The number of batches to prefetch in the dataloader
- persistent_workers: int = True#
Whether or not to keep workers persistent between epochs
- batch_size: int = <object object>#
Batch size to be used
- num_workers: int = 0#
The number of PyTorch processes used in the dataloader
- shuffle: bool = True#
Whether or not to shuffle the dataset
- shuffle_seed: int = 0#
Seed used for deterministic shuffling
