| TensorProtosDBInput is a simple input
| operator that basically reads things
| from a db where each key-value pair stores
| an index as key, and a TensorProtos object
| as value. These TensorProtos objects
| should have the same size, and they will
| be grouped into batches of the given
| size. The DB Reader is provided as input to
| the operator and it returns as many output
| tensors as the size of the
|
| TensorProtos object. Each output will
| simply be a tensor containing a batch
| of data with size specified by the ‘batch_size’
| argument containing data from the corresponding
| index in the
|
| TensorProtos objects in the DB.
