Missing tensor.name for all the input/output pb files in bertsquad-8.tar.gz

[winnietsang]

In text/machine_comprehension/bert-squad/model/bertsquad-8.tar.gz, there are input and output pb files. Base on the README.md of BERT-Squad model, there should have 4 inputs and 3 outputs, without the tensor.name defined in the pb files, it is very hard to determine which input is which and the same apply to output too. Further, there are 4 output pb files, output_3.pb should be deleted.

Filename	tensor.name
input_0.pb	unique_ids_raw_output___9:0
input_1.pb	input_ids:0
input_2.pb	input_mask:0
input_3.pb	segment_ids:0
output_0.pb	unique_ids:0
output_1.pb	unstack:0
output_2.pb	unstack:1
~~output_3.pb~~	There are only 3 outputs, this file should be deleted.
