numpy.may_share_memory — NumPy v2.6.dev0 Manual

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, bndarrayInput arrays

max_workint, optionalEffort to spend on solving the overlap problem. See

shares_memory

for details. Default for may_share_memory is to do a bounds check.

Returns:outboolExamples
