Constructs a descriptor for a convolution weights gradient primitive with bias.

Note
All the memory descriptors may be initialized with the dnnl::memory::format_tag::any value of format_tag.

Arrays strides, padding_l, and padding_r contain values for spatial dimensions only and hence must have the same number of elements as there are spatial dimensions. The order of values is the same as in the tensor: depth (for 3D tensors), height (for 3D and 2D tensors), and width.

Parameters
aalgorithmConvolution algorithm. Possible values are dnnl::algorithm::convolution_direct, dnnl::algorithm::convolution_winograd, and dnnl::algorithm::convolution_auto.
src_descSource memory descriptor.
diff_weights_descDiff weights memory descriptor.
diff_bias_descDiff bias memory descriptor. Passing zero memory descriptor disables the bias term.
diff_dst_descDiff destination memory descriptor.
stridesStrides for each spatial dimension.
padding_lVector of padding values for low indices for each spatial dimension ([[front,] top,] left).
padding_rVector of padding values for high indices for each spatial dimension ([[back,] bottom,] right).
