Constructor & Destructor Documentation

◆ primitive_desc() [1/3]

dnnl::gru_forward::primitive_desc::primitive_desc	(	const desc &	adesc,
		const engine &	aengine,
		bool	allow_empty = `false`
	)

inline

Constructs a primitive descriptor for a GRU forward propagation primitive.

Parameters

adesc	Descriptor for a 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.

		const primitive_attr &	attr,
		const engine &	aengine,
		bool	allow_empty = `false`
	)

inline

Constructs a primitive descriptor for a GRU forward propagation primitive.

Parameters

adesc	Descriptor for a GRU forward propagation primitive.
attr	Primitive attributes to use.
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.

◆ primitive_desc() [3/3]

dnnl::gru_forward::primitive_desc::primitive_desc ( dnnl_primitive_desc_t pd )

inline

Constructs a primitive descriptor for a GRU forward propagation primitive from a C API primitive descriptor that must have a matching kind.

Parameters

pd	C API primitive descriptor for a GRU forward propagation primitive.
