🐛 Describe the bug

Setting ["bridge_train"] to classes argument of LSUN() gets the error as shown below: *Memos:

It also happens with ["conference_room_train"], ["church_outdoor_train"], ["dining_room_train"] and ["tower_train"] for classes argument.
"test" doesn't work because test_lmdb.zip, test_train_lmdb.zip and test_val_lmdb.zip cannot be unzipped as I reported the bug.
There is other error as I reported here.

from torchvision import datasets

train_data = datasets.LSUN(
    root="C:/Users/<user>/dl-models/data/lsun",
    classes=["bridge_train"] # Here
) # Error

print(len(train_data))

CorruptedError: mdb_cursor_get: MDB_CORRUPTED: Located page was wrong type

Versions

import torchvision

torchvision.__version__ # '0.20.1'

Hi @hyperkai Can you please provide the entire traceback? It might help diagnose what's going on. As mentioned in https://github.com/pytorch/vision/issues/8767#issuecomment-2507945632 it's hard to repro as the original files aren't available anymore
