It enables users to manage multiple generator states via indices, offering a convenient way to switch between these states without directly manipulating the generator's state. Args: state_list(list|tuple): A list or tuple representing the RNG states for devices. If not provided, the function will register the current state. device(str): This parameter determines the specific running device. It can be ``cpu``, ``gpu``, ``xpu``, Default is None. If None, return the generators of current device (specified by ``set_device``). Returns: A list of indices representing the positions at which the new states were saved within the generator. These indices can be used to switch between states using set_rng_state(use_index=True) Examples: .. code-block:: python >>> import paddle >>> old_index = paddle.incubate.get_rng_state(use_index=True) >>> print(old_index) [0] >>> new_index = paddle.incubate.register_rng_state_as_index() >>> print(new_index) [1] >>> paddle.incubate.set_rng_state(old_index, use_index=True) >>> paddle.incubate.set_rng_state(new_index, use_index=True) NrTrUcr&r'r)r,r/rrr1 r2z/register_rng_state_as_index..rVrWrXrYrz@register_rng_state_index is not implemented for current device: )rr3Z_current_expected_placer6rr7rr;rZr=rFr<r9r>Zregister_state_indexr?r@rArBrCrDr[rEr*r8r:)rGrZnew_state_index_listrHrIrr/rregister_rng_state_as_indexst$    +        r])..)rrrrr r)rrrrr r )rrrr!r r")NF)rGrKrrrrr rL)rGrPrrrrr rL)rGrQrrrr!r rL)NN)rGr\rrr r) __future__rtypingrrr5rZ paddle.basercollections.abcrrr Zpaddle._typingr r __all__rrNr]rrrrsN      ;  R
