I don't know if I understand what you want, do you want me or someone
else to explain the section "What is the preferred way to test if an
array is empy?" in the scipy FAQ

If the arrays are the same size or can be broadcasted to the same
size, it returns true or false on an elementwise basis.
If the arrays are not the same size and can't be broadcasted to the
same size, it returns False, which was a surprise to me too.

I assume there is some reasoning behind this

The reasoning behind this is that == returns an array that specifies
whether each element of the two arrays is equal. It's only defined if
the arrays are the same shape (or maybe if they can be broadcasted to
the same shape).
The correct way to check if an array is empty is to inspect its .sh
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?
