from object_detection.protos import string_int_label_map_pb2

>Solution :

You just need to put that files in the same folder and just write

import string_int_label_map_pb2

instead of

from object_detection.protos import string_int_label_map_pb2

Also make sure you have converted protos files to .py file.
