title: Pandas read_csv not reading all rows in file
body: <p>I am trying to read a csv file with pandas. File has 14993 line after headers.</p>
  
  <pre><code>data = pd.read_csv(filename, usecols=['tweet', 'Sentiment'])
  print(len(data))
  </code></pre>
  
  <p>it prints : 14900 and if I add one line to the end of file it is now 14901 rows, so it is not because of memory limit etc. And I also tried "error_bad_lines" but nothing has changed.</p>
