title: ImportError: cannot import name 'string_int_label_map_pb2'
body: <p>I compiled the files with the following command.</p>
  
  <pre><code>protoc object_detection/protos/*.proto --python_out=.
  </code></pre>
  
  <p>and as a result compiled into .py files.</p>
  
  <p>However, I received the following error code.</p>
  
  <p>~/Documents/imgmlreport/inception/classification_inception/models/research/object_detection/utils/label_map_util.py in ()</p>
  
  <pre><code> 20 import tensorflow as tf
   21 from google.protobuf import text_format
  ---&gt; 22 from object_detection.protos import string_int_label_map_pb2
   23 
   24 
  
  ImportError: cannot import name 'string_int_label_map_pb2'
  </code></pre>
  
  <p>so i checked utils and i already had a string_int_label_map_pb2.py </p>
  
  <p>why can't import string_int_label_map_pb2.py ?</p>
