title: Is it possible to build tensorboard without tensorflow?
body: <p>TensorBoard is a good tool for visualization, but currently it's build together with TensorFlow, that means I have to install TF to use TB. </p>
  
  <p>I've found some hint to build it alone, from TensorBoard's document:
  <code>
  bazel build tensorflow/tensorboard:tensorboard
  </code></p>
  
  <p>So my question is, is it possible to build a <code>.whl</code> file of TensorBoard like the TensorFlow does:<br>
  <code>pip install --ignore-installed --upgrade $TF_BINARY_URL</code>. </p>
  
  <p>And user can just using pip install from a <code>.whl</code> file which is super easy.</p>
