Hi, I get this error while trying to train /

lmdb.Error: lmdb: No such file or directory

ERROR:torch.distributed.elastic.multiprocessing.api:failed (exitcode: 1) local_rank: 0 (pid: 4800) of binary: /usr/local/bin/python Traceback (most recent call last):

Does anyone know how I should proceed to debug this ?

Thanks

Can you first check your data path? "lmdb.Error: lmdb: No such file or directory", lmdb didn't find your file.
