title: Buffered data was truncated after reaching the output size limit
body: <p>When I use Colaboratory to run my NIN model, it occurs an error in the output of training process which tells "Buffered data was truncated after reaching the output size limit." in the 61th epoch. I have no idea about this crash.Is my code still running ? How can I solve this problem?</p>
  
  <p>Here is some information about the output of my training process:</p>
