Summary:
This examples writes a LMDB database of image data and labels (random). Then it reads them using Caffe2's TensorProtosDBINput and validates the checksums match. This example shows how to coerce image data into TensorProtos and be happy.
Before there was no clear example how to create databases for Caffe2.
