Detailed Description

Function Documentation

dnnl_status_t DNNL_API dnnl_resampling_backward_desc_init	(	dnnl_resampling_desc_t *	resampling_desc,
		dnnl_alg_kind_t	alg_kind,
		const float *	factors,
		const dnnl_memory_desc_t *	diff_src_desc,
		const dnnl_memory_desc_t *	diff_dst_desc
	)

Initializes a descriptor for resampling backward propagation primitive.

Parameters

resampling_desc	Output descriptor for a resampling primitive.
alg_kind	resamplinging algorithm kind: either dnnl_resampling_nearest, or dnnl_resampling_linear.
diff_src_desc	Diff source memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
factors	Array of scaling factors for spatial dimension.

Returns

dnnl_success on success and a status describing the error otherwise.

dnnl_status_t DNNL_API dnnl_resampling_forward_desc_init	(	dnnl_resampling_desc_t *	resampling_desc,
		dnnl_prop_kind_t	prop_kind,
		dnnl_alg_kind_t	alg_kind,
		const float *	factors,
		const dnnl_memory_desc_t *	src_desc,
		const dnnl_memory_desc_t *	dst_desc
	)

Initializes a descriptor for a resampling forward propagation primitive.

Note

Destination memory descriptor is allowed to be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Parameters

resampling_desc	Output descriptor for a resampling primitive.
prop_kind	Propagation kind. Possible values are dnnl_forward_training and dnnl_forward_inference.
alg_kind	resampling algorithm kind: either dnnl_resampling_nearest, or dnnl_resampling_linear.
factors	Array of scaling factors for spatial dimension.
src_desc	Source memory descriptor.
dst_desc	Destination memory descriptor.

Returns

dnnl_success on success and a status describing the error otherwise.
