- numpy.may_share_memory(a, b, max_work=None)¶
Determine if two arrays might share memory
A return of True does not necessarily mean that the two arrays share any element. It just means that they might.
Only the memory bounds of a and b are checked by default.
a, b : ndarray
max_work : int, optional
Effort to spend on solving the overlap problem. See shares_memory for details. Default for may_share_memory is to do a bounds check.
out : bool
>>> np.may_share_memory(np.array([1,2]), np.array([5,8,9])) False >>> x = np.zeros([3, 4]) >>> np.may_share_memory(x[:,0], x[:,1]) True
