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.
Parameters: a, b : ndarray
Input arrays
max_work : int, optional
Effort to spend on solving the overlap problem. See
shares_memory
for details. Default formay_share_memory
is to do a bounds check.Returns: out : bool
