title: Python kernel dies while doing a division in Pandas
body: <p>I have a csv the size is about 94.4 MB and it contains 143,940 rows and 63 columns. I am just trying to divide two columns and outputting the value in another column. The code I am executing is a very simple code. </p>
  
  <pre><code>DF['Col3'] = DF['Col1'] / DF['Col2']
  </code></pre>
  
  <p>Every time I execute this piece of code on my spyder3 or Jupyter Notebook the kernel dies I used to execute this code before but I dint have any problem. Now I get the error message </p>
  
  <blockquote>
    <p>Kernel died, restarting</p>
  </blockquote>
  
  <p>I am running python 2.7 and anaconda version 4.3.14 pandas version 0.19.2 on my laptop which has a 8 GB RAM. of which only 1 GB is utilized prior to running this code and utilizes 100% when I am running this code. </p>
