Comment(by rgommers):

 Actually, this will go wrong for many metrics.  This should be fixed for
 all of them at once, with a utility function like:

 def _validate_vector(u):
     u = np.asarray(u, order='c').squeeze()
     if u.ndim > 1:
         raise ValueError("Input vector should be 1-D.")
     return u
