title: tcmalloc: large alloc python in Google Colab
body: <p>I was trying to apply a deep learning algorithm(CNN) in python but after separating training-testing data and transforming time series to image step my <strong>Colab Notebook</strong> crashed and restarted itself again.</p>
  <p>It gives an error like <strong>&quot;Your session crashed after using all RAM&quot;</strong> and when I checked <code>app.log</code> I saw something about <strong>tcmalloc: large alloc</strong>. I didn't find anything to fix this crashed.</p>
  <p>Do you have any idea how to prevent this warning and fixed this situation?</p>
