title: Google Colab causes high memory usage in local?
body: <p>I'm now running a model training on Google Colab. It was just a minute ago, the local system message popped out and said that the memory is about to exhaust (meanwhile I didn't run anything).</p>
  
  <p>Now my memory usage is 40%, but everytime I open up Colab, the local memory usage peak to 80 and keeps increasing. The Colab page freeze so I couldn't stop the current runtime.</p>
  
  <p>How is that possible? Shouldn't Colab be an online environment? Can it be related to the <code>tqdm</code> package? Because previous version ran well, this situation only happens when I just add <code>tqdm</code> to show progress bars on the screen.</p>
