title: TensorBoard Distributions and Histograms with Keras and fit_generator
body: <p>I'm using Keras to train a CNN using the fit_generator function.</p>
  
  <p>It seems to be a <a href="https://github.com/fchollet/keras/issues/3358" rel="noreferrer">known issue</a> that TensorBoard doesn't show histograms and distributions in this setup.</p>
  
  <p>Did anybody figure out a way to make it work anyway?</p>
