)
Creates a primitive descriptor for an inner product 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. |
src_desc |
Source memory descriptor. |
weights_desc |
Weights memory descriptor. |
bias_desc |
Bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to dnnl_format_kind_undef disables the bias term. |
dst_desc |
Destination memory descriptor. |
attr |
Primitive attributes (can be NULL). |
Returns:
dnnl_success on success and a status describing the error otherwise.

const_dnnl_primitive_attr_t attr
)
Creates a primitive descriptor for an inner product backward propagation primitive.
Parameters:
primitive_desc |
Output primitive_descriptor. |
engine |
Engine to use. |
diff_src_desc |
Diff source memory descriptor. |
weights_desc |
Weights memory descriptor. |
diff_dst_desc |
Diff destination memory descriptor. |
hint_fwd_pd |
Primitive descriptor for a respective forward propagation primitive. |
attr |
Primitive attributes (can be NULL). |
Returns:
dnnl_success on success and a status describing the error otherwise.
