title: How to write graph to tensorboard using tensorflow 2.0?
body: <p>Am doing this</p>
  
  <pre><code>    # eager on
      tf.summary.trace_on(graph=True, profiler=True)
      tf.summary.trace_export('stuff', step=1, profiler_outdir='output')
      # ... call train operation
      tf.summary.trace_off()
  </code></pre>
  
  <p>Profile section shows up in tensorboard but no graph yet.</p>
