Global Functions
dnnl_status_t DNNL_API dnnl_shuffle_forward_desc_init( dnnl_shuffle_desc_t* shuffle_desc, dnnl_prop_kind_t prop_kind, const dnnl_memory_desc_t* data_desc, int axis, dnnl_dim_t group_size )
Initializes a descriptor for shuffle forward propagation primitive.
Parameters:
shuffle_desc
Output descriptor for a shuffle primitive.
prop_kind
Propagation kind. Possible values are dnnl_forward_training and dnnl_forward_inference.
data_desc
Source and destination memory descriptor.
axis
The axis along which the data is shuffled.
group_size
Shuffle group size.
Returns:
dnnl_success on success and a status describing the error otherwise.
dnnl_status_t DNNL_API dnnl_shuffle_backward_desc_init( dnnl_shuffle_desc_t* shuffle_desc, const dnnl_memory_desc_t* diff_data_desc, int axis, dnnl_dim_t group_size )
Initializes a descriptor for shuffle backward propagation primitive.
Parameters:
shuffle_desc
Output descriptor for a shuffle primitive.
diff_data_desc
Diff source and diff destination memory descriptor.
axis
The axis along which the data is shuffled.
group_size
Shuffle group size.
Returns:
dnnl_success on success and a status describing the error otherwise.
