Detailed Description

Primitive descriptor for a layer normalization backward propagation primitive.

Constructor & Destructor Documentation

◆ primitive_desc() [1/3]

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

inline

Constructs a primitive descriptor for a layer normalization backward propagation primitive.

Parameters

adesc	Descriptor for a layer normalization backward propagation primitive.
aengine	Engine to use.
hint_fwd_pd	Primitive descriptor for a layer normalization forward propagation primitive. It is used as a hint for deciding which memory format 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.

		bool	allow_empty = `false`
	)

inline

Constructs a primitive descriptor for a layer normalization backward propagation primitive.

Parameters

adesc	Descriptor for a layer normalization backward propagation primitive.
attr	Primitive attributes to use.
aengine	Engine to use.
hint_fwd_pd	Primitive descriptor for a layer normalization forward propagation primitive. It is used as a hint for deciding which memory format 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::layer_normalization_backward::primitive_desc::primitive_desc ( dnnl_primitive_desc_t pd )

inline

Constructs a primitive descriptor for a layer normalization backward propagation primitive from a C API primitive descriptor that must have a matching kind.

Parameters

pd	C API primitive descriptor for a layer normalization backward propagation primitive.
