title: Running code cells sequentially in google colab
body: <p>I want to run the code cells in Google Colab in sequence.</p>
  
  <p>For example:</p>
  
  <p>Cell[1]</p>
  
  <pre><code>from catboost import CatBoostRegressor
  #do something here
  </code></pre>
  
  <p>Cell[2]</p>
  
  <pre><code>clf = CatBoostRegressor(task_type='GPU')
  #do some more things here
  </code></pre>
  
  <p>But when I select "Run all" all cells seem to run in parallel, so my code does not work.</p>
  
  <p>When I do the same thing in a Kaggle Kernel it runs perfectly i.e, first cell[1] is executed, and then cell[2] and so on.</p>
  
  <p>I have tried searching for this in Google Colab but failed to come up with an answer. </p>
