title: how to close tensorboard server with jupyter notebook
body: <p>what is the proper way to close tensorboard with jupyter notebook? </p>
  
  <p>I'm coding tensorflow on my jupyter notebook.                                        To launch, I'm doing:                                                                     1.  </p>
  
  <ol>
  <li><code>!tensorboard --logdir = logs/</code></li>
  <li>open a new browser tab and type in <code>localhost:6006</code></li>
  </ol>
  
  <p>to close, I just do:</p>
  
  <ol>
  <li>close the tensorflow tab on my browser</li>
  <li>on jupyter notebook, I click on interrupt kernel </li>
  </ol>
  
  <p>Just wondering if this is the proper way....</p>
  
  <p>BTW, in my code I set my log file as './log/log1'. 
  when starting tensorboard, should I use <code>--logdir = ./log</code>  or <code>--logdir = ./log/log1</code>?   </p>
  
  <p>thank you very much. </p>
