title: I can't run Tensorboard in Ubuntu
body: <p>A couple of days ago I ran Tensorboard in Ubuntu and I got results without any problem.</p>
  
  <p>I used a pre-trained model and I want to put the results into Tensorboard. From models / object_detection folder, I run the command: </p>
  
  <pre><code>tensorboard --bind_all --port 6006 --logdir=’training’
  </code></pre>
  
  <p>and I got the response:</p>
  
  <pre><code>tensorboard is active on ip and port TensorBoard 2.0.2 at http://ubuntu:6006/ (Press CTRL+C to quit).
  </code></pre>
  
  <p>So I went on the web and took my results graphs etc.</p>
  
  <p>Today, I did the same but I got the above errors:</p>
  
  <pre><code>TensorBoard 2.0.2 at http://ubuntu:6006/ (Press CTRL+C to quit)
