title: ImportError: No module named 'deployment'
body: <p>Not sure whether I should be posting this on askubuntu or here.
  I am trying to perform object detection using Tensorflow. I am therefor following <a href="https://youtu.be/JR8CmWyh2E8?t=709" rel="noreferrer">this tutorial</a> (this link shows the exact issue I am facing).</p>
  
  <p>When running <a href="https://github.com/tensorflow/models/blob/master/research/object_detection/train.py" rel="noreferrer">this script</a>, I get this error:</p>
  
  <pre><code>$ python3 train.py --logtostderr --train_dir=training/ --pipeline_config_path=training/ssd_mobilenet_v1_pets.config 
  Traceback (most recent call last):
    File "train.py", line 51, in &lt;module&gt;
      from object_detection import trainer
    File "/usr/local/lib/python3.5/dist-packages/object_detection-0.1-py3.5.egg/object_detection/trainer.py", line 33, in &lt;module&gt;
      from deployment import model_deploy
  ImportError: No module named 'deployment
  </code></pre>
  
  <p>According to the info I found online and the video I linked above I have to execute this command:</p>
  
  <pre><code>export PYTHONPATH=$PYTHONPATH:`pwd`/slim
  </code></pre>
  
  <p>While being in the <code>tensorflow/model/</code> directory. Yet, it doesn't solve my issue. And I don't really know what I should check in order to find out what is causing this persistent issue.</p>
  
  <p>Could someone help me out?</p>
  
  <p>Thanks</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>exactly what I do:</p>
