title: TensorBoard doesn't find scalar statistics
body: <p>Has anyone gotten TensorBoard working? Doesn't seem to find my ScalarSummary files.
  I'm using:</p>
  
  <pre><code>$ python /Users/nikhilbuduma/tensorflow/lib/python2.7/site-packages/tensorflow/tensorboard/tensorboard.py --logdir=~/Documents/tensorflow_playground/feedforward_mnist/data
  </code></pre>
  
  <p>and: <code>~/Documents/tensorflow_playground/feedforward_mnist/data</code> contains a file called <code>events.out.tfevents.1447172341.31-34-222.wireless.csail.mit.edu</code></p>
  
  <p>Which I assume are the scalar summaries?</p>
