title: Libsvm : Wrong input format at line 1
body: <p>I am trying to use <a href="https://github.com/cjlin1/libsvm" rel="nofollow noreferrer">Libsvm</a> and I got the following behaviour:</p>
  
  <pre><code>root@bcfd88c873fa:/home/libsvm# ./svm-train myfile
  Wrong input format at line 1
  root@bcfd88c873fa:/home/libsvm# head -n 5 myfile
  2   0:0.00000 8:0.00193 2:0.00000 1:0.00000 10:0.00722
  3   6:0.00235 2:0.00000 0:0.00000 1:0.00000 5:0.00155
  4   0:0.00000 1:0.00000 2:0.00000 4:0.00187
  3   6:0.00121 8:0.00211 1:0.00000 2:0.00000 0:0.00000
  3   0:0.00000 2:0.00000 1:0.00000
  </code></pre>
  
  <p>Can you see anything wrong on the format ? It works with other svm implementation such as <a href="https://github.com/xlvector/hector" rel="nofollow noreferrer">this one</a> in Go.</p>
  
  <p>Thanks,</p>
