Detailed Documentation
Primitive descriptor for a resampling forward propagation primitive.
Construction
primitive_desc()
Default constructor. Produces an empty object.
primitive_desc(
const engine& aengine,
prop_kind aprop_kind,
algorithm aalgorithm,
const memory::desc& src_desc,
const memory::desc& dst_desc,
const primitive_attr& attr = default_attr(),
bool allow_empty = false
)
Constructs a primitive descriptor for a resampling forward propagation primitive using source and destination memory descriptors.
Parameters:
aengine |
Engine to use. |
aprop_kind |
Propagation kind. Possible values are dnnl::prop_kind::forward_training, and dnnl::prop_kind::forward_inference. |
aalgorithm |
resampling algorithm kind: either dnnl::algorithm::resampling_nearest, or dnnl::algorithm::resampling_linear |
src_desc |
Source memory descriptor. |
dst_desc |
Destination memory descriptor. |
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. |

)
Constructs a primitive descriptor for a resampling forward propagation primitive using source memory descriptor and factors.
Parameters:

factors |
Vector of scaling factors for spatial dimension. |
src_desc |
Source memory descriptor. |
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 resampling forward propagation primitive from a C API primitive descriptor that must have a matching kind.
Parameters:
pd |
C API primitive descriptor for a resampling 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.
