Environment: CentOS 7 + Python 3.4

Description: When I use "bazel build tensorflow_serving/..." to build the tensorflow_serving source codes under python 3.4, I met the above error.

Solution:
I made the following modifications to make the codes work for both python 2.x and python 3.x:

1. In "serving/tensorflow_serving/session_bundle/example/export_half_plus_two.py", add
   from __future__ import print_function
   and change
   print "copying asset files to: %s" % export_path
   to
   print ("copying asset files to: %s" % export_path)
2. In "serving/tensorflow_serving/session_bundle/exporter.py",

import six
.....
#for name, tensor in name_tensor_map.iteritems():
for name, tensor in six.iteritems(name_tensor_map):
......
#for signature_name, signature in named_graph_signatures.iteritems():
for signature_name, signature in six.iteritems(named_graph_signatures):
.......
