title: TensorBoard not working
body: <p>I'm able to use TensorFlow just fine. But I can't yet use TensorBoard at all. I'm following the instructions on tensorflow.org's <a href="https://www.tensorflow.org/versions/r0.7/how_tos/summaries_and_tensorboard/index.html" rel="noreferrer">Visualizing Learning page</a>.</p>
  
  <p>When I run</p>
  
  <pre><code>tensorboard --logdir=/tmp/mnist_logs --debug
  </code></pre>
  
  <p>I get the following</p>
  
  <pre><code>INFO:tensorflow:TensorBoard is in debug mode.
