Global Functions
dnnl_status_t DNNL_API dnnl_concat_primitive_desc_create( dnnl_primitive_desc_t* concat_primitive_desc, const dnnl_memory_desc_t* dst_desc, int n, int concat_dimension, const dnnl_memory_desc_t* src_descs, const_dnnl_primitive_attr_t attr, dnnl_engine_t engine )
Creates a primitive descriptor for an out-of-place concatenation primitive.
Parameters:
concat_primitive_desc
Output primitive descriptor.
dst_desc
Destination memory descriptor.
n
Number of source parameters.
concat_dimension
Source tensors will be concatenated over dimension with this index. Note that order of dimensions does not depend on memory format.
src_descs
Array of source memory descriptors with
n
elements.
attr
Primitive attributes to use (can be NULL).
engine
Engine to use.
Returns:
dnnl_success on success and a status describing the error otherwise.
