Detailed Documentation

Primitive descriptor for a pooling forward propagation primitive.

Construction

primitive_desc()

Default constructor. Produces an empty object.

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

Constructs a primitive descriptor for a pooling v2 (dilated pooling) forward propagation primitive.

Parameters:

adesc	Descriptor for a pooling 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.

primitive_desc(
    const desc& adesc,
    const primitive_attr& attr,
    const engine& aengine,
    bool allow_empty = false
    )

Constructs a primitive descriptor for a pooling v2 (dilated pooling) forward propagation primitive.

Parameters:

adesc	Descriptor for a pooling forward propagation primitive.
aengine	Engine to use.
attr	Primitive attributes 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 pooling v2 (dilated pooling) forward propagation primitive from a C API primitive descriptor that must have a matching kind.

Parameters:

pd	C API primitive descriptor for a pooling 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.

memory::desc workspace_desc() const

Returns the workspace memory descriptor.

Returns:

Workspace memory descriptor.

A zero memory descriptor if the primitive does not require workspace parameter.
