Conversion happens on first run only.
When changing pre_transforms you need to manually delete previously generated dataset files!
Args:
data_dir (str): Path to data folder.
train_val_test_split (Sequence[int]): Number of datapoints for training, validation and testing. Should sum up to 70_000.
n_segments (int): Number of superpixels per image.
sp_generation_workers (int): Number of processes for superpixel dataset generation.
batch_size (int): Batch size.
num_workers (int): Number of processes for data loading.
pin_memory (bool): Whether to pin CUDA memory (slight speed up for GPU users).
**kwargs : Extra paramters passed to SLIC algorithm, learn more here:
