Question about SA1B dataset

[Venn2336]

Thank you so much for your contribution to SAMTok, when I conducted the training procedure, I found some questions about this dataset from the "projects/samtok/docs/TRAIN_TOKENIZER.md", could you tell me the correct path of this config?

sa1b_dataset = dict(
type=SA1BDataset,
image_folder=DATA_ROOT,
preprocessor=sam2_image_processor,
multi_targets=False,
repeats=20,
fast_load=True,
sam_info_json=sam_info_json,
scan_record_folder='./left_sa1b_indices/vq_sam2_256x2_unshare/'
)
