numpy.shares_memory

numpy.shares_memory(a, b, max_work=None)

Determine if two arrays share memory
Parameters: 

a, b : ndarray 
Input arrays 
max_work : int, optional 
Effort to spend on solving the overlap problem (maximum number of candidate solutions to consider). The following special values are recognized:  max_work=MAY_SHARE_EXACT (default)

The problem is solved exactly. In this case, the function returns True only if there is an element shared between the arrays.  max_work=MAY_SHARE_BOUNDS

Only the memory bounds of a and b are checked. 
Returns: 

out : bool 
Raises: 
 numpy.TooHardError

Exceeded max_work. 
Examples
>>> np.may_share_memory(np.array([1,2]), np.array([5,8,9]))
False
