I am pretty new user, but I tend to use shape (n.shape) to check empty
array. You can even check n.size to determine if its empty or not.

Subject: [Numpy-discussion] equality of empty arrays
I assume there is some reasoning behind this
>>> m = np.array([])
>>> n = np.array([])
>>> m==n
array([], dtype=bool)
I was expecting somthing like.
>>> m = []
>>> n = []
>>> m==n
True
What is the right way to test if an array is empty?
