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

.. note:: 

   All the memory descriptors may be initialized with the :ref:`dnnl::memory::format_tag::any <doxid-structdnnl_1_1memory_1a8e71077ed6a5f7fb7b3e6e1a5a2ecf3fa100b8cad7cf2a56f6df78f171f97a1ec>` 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.
