CIFAR10DataModule
¶
Bases: LightningDataModule
A LightningDataModule for handling CIFAR10 data.
Torchvision provides many built-in datasets in the torchvision.datasets module,
as well as utility classes for building your own datasets. All datasets are subclasses of torch.utils.data.Dataset i.e, they have getitem and len methods implemented. Hence, they can all be passed to a torch.utils.data.DataLoader which can load multiple samples in parallel using torch.multiprocessing workers, see [1].
Parameters:

---|---|---|---|
batch_size |
int

required |
data_dir |
str
|
