numpy.may_share_memory#

numpy.may_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.

Parameters:

a, bndarray

Input arrays

max_workint, 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.

Returns:

outbool
