Detailed Documentation

Primitive descriptor for a shuffle forward propagation primitive.

Construction


primitive_desc()

Default constructor. Produces an empty object.


primitive_desc(
    const engine& aengine,
    prop_kind aprop_kind,
    const memory::desc& src_desc,
    const memory::desc& dst_desc,
    int axis,
    int group_size,
    const primitive_attr& attr = default_attr(),
    bool allow_empty = false
    )

Constructs a primitive descriptor for a shuffle forward propagation primitive.

Parameters:

aengine	Engine to use.
aprop_kind	Propagation kind. Possible values are dnnl::prop_kind::forward_training, and dnnl::prop_kind::forward_inference.
src_desc	Source memory descriptor.
dst_desc	Destination memory descriptor.
axis	The axis along which the data is shuffled.
group_size	Shuffle group size.
attr	Primitive attributes to use. Attributes are optional and default to empty attributes.
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 shuffle forward propagation primitive from a C API primitive descriptor that must have a matching kind.

Parameters:

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

Methods


memory::desc src_desc() const

Returns a source memory descriptor.

Returns:

Source memory descriptor.

A zero memory descriptor if the primitive does not have a source parameter.


memory::desc dst_desc() const

Returns a destination memory descriptor.

Returns:

Destination memory descriptor.

A zero memory descriptor if the primitive does not have a destination parameter.


prop_kind get_prop_kind() const

Returns a propagation kind.

Returns:

A propagation kind.

dnnl::prop_kind::undef if the primitive does not have a propagation parameter.


int get_axis() const

Returns an axis.

Returns:

An axis.

A negative number if the primitive does not have an axis parameter.


memory::dim get_group_size() const

Returns a group size parameter.

Returns:

A group size parameter.

Zero if the primitive does not have a group size parameter.
