Cannot construct TileDataset

[Michaelsqj]

Hi, Dr. Lin, I think if the dataset returned here

pytorch_connectomics/connectomics/data/dataset/__init__.py

Line 141 in 36c185d

dataset = get_dataset(cfg, augmentor, mode)

by get_dataset() is a TileDataset, the dataloader might not be able to be constructed from it. Since _len_(), and _get_item_() is not defined in TileDataset, unless

pytorch_connectomics/connectomics/data/dataset/dataset_tile.py

Line 72 in 36c185d

def updatechunk(self, do_load=True):

is called and construct the dataloader from a VolumeDataset. I haven't used TileDataset, please correct me if I'm wrong.
