dnnl_softmax_v2_backward_desc_init()

dnnl_status_t DNNL_API dnnl_softmax_v2_backward_desc_init	(	dnnl_softmax_v2_desc_t *	softmax_desc,
		dnnl_alg_kind_t	alg_kind,
		const dnnl_memory_desc_t *	diff_src_desc,
		const dnnl_memory_desc_t *	diff_dst_desc,
		const dnnl_memory_desc_t *	dst_desc,
		int	softmax_axis
	)

Initializes a descriptor for softmax v2 backward propagation primitive.

Parameters

softmax_desc	Output descriptor for a softmax primitive.
alg_kind	Softmax algorithm kind: either dnnl_softmax_accurate, or dnnl_softmax_log.
diff_src_desc	Diff source memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
dst_desc	Destination memory descriptor.
softmax_axis	Axis over which softmax is computed.

Returns

dnnl_success on success and a status describing the error otherwise.
