Scrambles seed into key and counter, using the best algorithm based on device.
This op scrambles a shape-[2] seed into a key and a counter, both needed by counter-based RNG algorithms. The scrambing uses the best algorithm based on device. The scrambling is opaque but approximately satisfies the property that different seed results in different key/counter pair (which will in turn result in different random numbers).

Public Methods
public Output <?> counter ()
Counter for the counter-based RNG algorithm. Since counter size is algorithm-dependent, this output will be right-padded with zeros to reach shape uint64[2] (the current maximal counter size among algorithms).
public static StatelessRandomGetKeyCounter create ( Scope scope, Operand <T> seed)
Factory method to create a class wrapping a new StatelessRandomGetKeyCounter operation.
Parameters
scope | current scope |
---|---|
seed | 2 seeds (shape [2]). |
Returns
- a new instance of StatelessRandomGetKeyCounter
