title: ModuleNotFoundError: No module named 'object_detection'
body: <p>i try to train.py in object_detection in under git url</p>
  
  <p><a href="https://github.com/tensorflow/models/tree/master/research/object_detection" rel="noreferrer">https://github.com/tensorflow/models/tree/master/research/object_detection</a></p>
  
  <p>However, the following error occurs.</p>
  
  <blockquote>
    <p>ModuleNotFoundError: No module named 'object_detection'</p>
  </blockquote>
  
  <p>So I tried to solve the problem by writing the following code.</p>
  
  <pre><code>import sys
  
  sys.path.append('/home/user/Documents/imgmlreport/inception/models/research/object_detection')
  from object_detection.builders import dataset_builder
  </code></pre>
  
  <p>This problem has not been solved yet.</p>
  
  <p>The directory structure is shown below.</p>
  
  <pre><code>~/object_detection/train.py
  
  ~/object_detection/builders/dataset_bulider.py
  </code></pre>
  
  <p>and here is full error massage</p>
  
  <blockquote>
