title: How to run tensorboard in vscode?
body: <p>Whenever I try to run tensorboard in a jupyter notebook within visual studio code with this command <code>tensorbard --logdir=runs</code>, I get the message <code>Launching TensorBoard...</code>. However, Tensorboard never launches. Sometimes I also get an error message.</p>
  <p>Any ideas on how to launch tensorboard within vscode?</p>
  <p><strong>EDIT:</strong></p>
  <p>I also tried running slightly optimized commands</p>
  <pre><code>%load_ext tensorboard
  %tensorboard --logdir runs
  </code></pre>
  <p>but this only shows the message <code>Launching Tensorboard...</code> eternally.</p>
  <p>Same result with</p>
  <pre><code>%reload_ext tensorboard
  %tensorboard --logdir runs --host localhost --port 8888
  </code></pre>
  <p>Is there any tensorboard extension that embeds tensorboard into a cell output?</p>
