title: Python error: Big-endian buffer not supported on little-endian compiler
body: <p>When i run my python code (a very simple piece of code that was previously tested and no such error occured), i got this error:</p>
  
  <p> ValueError: Big-endian buffer not supported on little-endian compiler</p>
  
  <p>My Code (partial):</p>
  
  <pre><code>key = '|'.join(dealList)
  
  print key  #key is the column name i'm searching for
  try:
  
      #use REGEX since dealID is not exactly the same as the col name
      dealVector0 = self.crm_var0.filter(regex=key)
      dealVector1 = self.crm_var1.filter(regex=key)
      ...
  </code></pre>
  
  <p>self.crm_var1 is a pandas dataframe</p>
