Global Functions¶
dnnl_status_t DNNL_API dnnl_softmax_v2_forward_desc_init( dnnl_softmax_v2_desc_t* softmax_desc, dnnl_prop_kind_t prop_kind, dnnl_alg_kind_t alg_kind, const dnnl_memory_desc_t* src_desc, const dnnl_memory_desc_t* dst_desc, int softmax_axis )
Initializes a descriptor for softmax v2 forward propagation primitive.
Parameters:
softmax_desc |
Output descriptor for a softmax primitive. |
prop_kind |
Propagation kind. Possible values are dnnl_forward_training and dnnl_forward_inference. |
alg_kind |
Softmax algorithm kind: either dnnl_softmax_accurate, or dnnl_softmax_log. |
src_desc |
Source 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.
