Ok thanks… I dont know because using the LMDB generated by Caffe. Not sure internals of it. For now I have to stick to Caffe for the use case I’m addressing.
One request is it would be great if we get generic utilities to prepare the dataset in LMDB, HDF5,LIST that is compatible with Pytorch ( Goes through the iterator and batch perfectly)  for seamless data loading and data preparation. Lot of time is wasted after this.
Regards
