title: Reading text file with numpy.loadtxt
body: <p>I am getting an error when trying to read a text file. </p>
  
  <pre><code>import numpy as np
  
  fnam = 'file.txt'
  test_fnames = np.loadtxt(fnam, dtype=None, delimiter=',')
  test_fnames
  </code></pre>
  
  <p>I now get this error:</p>
  
  <pre><code>ValueError: could not convert string to float: 
  </code></pre>
  
  <p>The file content is just a comma separated list of numbers. Perhaps there is a space at the end of the file that is causing an error?</p>
  
  <pre><code>1,2,3,4,5,6,7,7,8,9122,3,3,45,5,6 
  </code></pre>
  
  <p>Thanks. The problem was the way I wrote the text file in Torch7. </p>
