title: Colaboratory|OSError: [Errno 5] Input/output error
body: <p><strong>Colaboratory</strong></p>
  
  <p>There is no error or bug in code and when I run the processing a few times, it will send the error. When I run the epoch, the first epoch never has an error, but the second epoch (or even the third) will have some trouble. I think it makes some mistakes on the path through the colab between my windows.  </p>
