title: Load txt file into numpy array
body: <p>I want to load a txt file into a numpy array. The file has this format:</p>
  
  <pre><code>1,10,1,11,1,13,1,12,1,1,9
  2,11,2,13,2,10,2,12,2,1,9
  3,12,3,11,3,13,3,10,3,1,9
  4,10,4,11,4,1,4,13,4,12,9
  4,1,4,13,4,12,4,11,4,10,9
  1,2,1,4,1,5,1,3,1,6,8
  1,9,1,12,1,10,1,11,1,13,8
  2,1,2,2,2,3,2,4,2,5,8
  3,5,3,6,3,9,3,7,3,8,8
  4,1,4,4,4,2,4,3,4,5,8
  .
  .
  .
  </code></pre>
  
  <p>a width of 11 values and a height of 25010 (so I don't want to put them manually into the array)</p>
  
  <p>I already tried <code>load</code>, <code>loadtxt</code>, <code>loadfile</code> and <code>genfromtxt</code>. All of them failed.
  I'm pretty sure the commas are the problem.</p>
  
  <p>You have a solution?</p>
