`numpy:may_share_memory`

Signature

built-inmay_share_memory(a, b, /, max_work = 0)

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: Input arrays
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.

import numpy as np
np.may_share_memory(np.array([1,2]), np.array([5,8,9]))
x = np.zeros([3, 4])
np.may_share_memory(x[:,0], x[:,1])
