Detailed Documentation

Primitive descriptor for a GRU backward propagation primitive.

Construction

primitive_desc()

Default constructor. Produces an empty object.

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

Constructs a primitive descriptor for a GRU backward propagation primitive.

Parameters:

adesc	Descriptor for a GRU backward propagation primitive.
aengine	Engine to use.
hint_fwd_pd	Primitive descriptor for a GRU 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(
    const desc& adesc,
    const primitive_attr& attr,
    const engine& aengine,
    const gru_forward::primitive_desc& hint_fwd_pd,
    bool allow_empty = false
    )

Constructs a primitive descriptor for a GRU backward propagation primitive.

Parameters:

adesc	Descriptor for a GRU backward propagation primitive.
attr	Primitive attributes to use.
aengine	Engine to use.
hint_fwd_pd	Primitive descriptor for a GRU 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(dnnl_primitive_desc_t pd)

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

Parameters:

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