title: Exception : "Invalid norm order for vectors" - Python
body: <p>i was trying to normalize a vector in python using numpy. I did the following:</p>
  
  <pre><code>matrix_norm = numpy.linalg.norm(matrix1[:,0], ord='fro')
  print(matrix_norm)
  </code></pre>
  
  <p>The matrix1 is of size: 1000 X 1400. I tried find the normalization value for the first column of the matrix. And it gives me the following exception:</p>
  
  <p>"Invalid norm order for vectors"</p>
  
  <p>Please help !
  Thanks in advance... :)</p>
