title: Tensorflow Object Detection API / ImportError: cannot import name 'keypoint_box_coder_pb2'
body: <p>I followed instructions (<a href="https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md" rel="nofollow noreferrer">https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md</a>) to install the Tensorflow Object Detection
  API. I use Anaconda on Windows 10 and all of the steps in the instructions seemed to complete OK. </p>
  
  <p>But when trying to run python object_detection/builders/model_builder_test.py to test the installation, I get: ImportError: cannot import name 'keypoint_box_coder_pb2'</p>
  
  <p>What am I missing?</p>
