		)

Constructs a primitive descriptor for a LBR GRU forward propagation primitive.



.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- adesc

		- Descriptor for a LBR GRU forward propagation primitive.

	*
		- aengine

		- Engine to use.

	*
		- allow_empty

		- A flag signifying whether construction is allowed to fail without throwing an exception. In this case an empty object will be produced. This flag is optional and defaults to false.
