title: TypeError : unhashable type
body: <p>Not completely sure if it's scipy related that's why I include the python tag.</p>
  
  <p>I have a grid of data. Whenever I try to access something in the grid like this :</p>
  
  <pre><code>d = pd.read_csv('Debugdata1.csv') 
  d[1,:]
  </code></pre>
  
  <p>I get <code>TypeError: unhashable type</code></p>
  
  <p>Took a look at the data in a variable explorer : the <code>Index</code> of my data looks like this (1L,32,432 ... some more integers). Could this be the problem?</p>
  
  <p>Here's the stack trace : </p>
