how to train sa-1b dataset?

[argu0]

File "/home/ar.gu/DINOv/datasets/build.py", line 149, in get_detection_dataset_dicts
assert len(dicts), "Dataset '{}' is empty!".format(dataset_name)
AssertionError: Dataset 'sam_train' is empty!

sam_train is registered in catalog.
but i think the path of sa-1b dataset is wrong.

can you tell me how i should make the dataset path?

i have

sa-1b |--- annotations (.tsv)
|----images (.jpg)
