lmdb.CorruptedError: mdb_get: MDB_CORRUPTED: Located page was wrong type

[Tclz]

When i download the feature file data.mdb(58.7G) in VCR project, and run the eval_tasks.py, i meet the following errors.
Traceback (most recent call last):
File "eval_tasks.py", line 231, in
main()
File "eval_tasks.py", line 172, in main
= LoadDatasetEval(args, task_cfg, args.tasks.split('-'))
File "/home/vilbert_beta/vilbert/task_utils.py", line 283, in LoadDatasetEval
args.in_memory)
File "/home/vilbert_beta/vilbert/datasets/_image_features_reader.py", line 47, in init
self._image_ids = pickle.loads(txn.get('keys'.encode()))
lmdb.CorruptedError: mdb_get: MDB_CORRUPTED: Located page was wrong type

I don't know what's wrong with the .mdb files and please tell me how to fix it.
Thanks in advance!!
