Global Functions
dnnl_status_t DNNL_API dnnl_softmax_forward_primitive_desc_create( dnnl_primitive_desc_t* primitive_desc, dnnl_engine_t engine, 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, const_dnnl_primitive_attr_t attr )
Creates a primitive descriptor for a softmax forward propagation primitive.
Parameters:
primitive_desc |
Output primitive descriptor. |
engine |
Engine to use. |
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. |
attr |
Primitive attributes (can be NULL). |
Returns:
dnnl_success on success and a status describing the error otherwise.
