title: Colaboratory install Tensorflow Object Detection Api
body: <p>I succesfully executed in Google Colaboratory a notebook of training model and image recognition in Tensorflow.
  Now I want to start a new notebook with <a href="https://github.com/tensorflow/models/tree/master/research/object_detection" rel="nofollow noreferrer">Object Detection Api</a>. When I execute my code I get following error:</p>
  
  <pre><code>ModuleNotFoundError: No module named 'object_detection'
  </code></pre>
  
  <p>How can I install Object Detection Api in Colaboratory? I follow the install <a href="https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md" rel="nofollow noreferrer">instructions</a> but I can't execute:</p>
  
  <pre><code># From tensorflow/models/research/
  protoc object_detection/protos/*.proto --python_out=.
  </code></pre>
