Member Function Documentation

def caffe2.python.db_file_reader.DBFileReader.setup_ex	(		self,
			init_net,
			finish_net
	)

From the Dataset, create a _DatasetReader and setup a init_net.

Make sure the _init_field_blobs_as_empty(...) is only called once.

Because the underlying NewRecord(...) creats blobs by calling
NextScopedBlob(...), so that references to previously-initiated
empty blobs will be lost, causing accessibility issue.
