title: tensorboard average of scalar summaries
body: <p>I am trying to visualize my output loss values with TensorBoard. The way I do it is straightforward. I just add a summary.scalar after each iteration over a minibatch. In the end of one epoch tensorboard will show me all the losses after each iteration. I want to get the average of all these iterations, meaning I want tensorboard to show me one loss value for each epoch.</p>
  
  <p>Thank you.</p>
