title: How to eliminate a dummy dimension of ndarray?
body: <p>How can I eliminate a dummy dimension in python numpy ndarray?<br>
  For example, suppose that A.shape = (0, 1325, 3),<br>
  then how can eliminate '0' dimension so that A.shape = (1325,3).  </p>
  
  <p>Both 'np.sqeeze(A)' or 'A.reshape(A.shape[1:])' don't work.</p>
