**Naming conventions**

1. ``A_B`` means change from layout format ``A`` to ``B``.
2. ``INTER_WEIGHT_xx`` means relayout the weight for faster processing by
   :attr:`Convolution.Format.NHWCD4` convolutions.
3. A suffix of ``I`` means ``Image2DPack4TensorFormat`` tensor format is used
   for faster processing on GPUs.

**Layout definitions**

* ``NCHW`` layout: ``{N, C, H, W}``
* ``NHWC`` layout: ``{N, H, W, C}``
* ``NHWCD4`` layout: ``{N, H, (C + 3) / 4, W, 4}``
* ``NHWCD4I`` layout: with ``align_axis = 2``
* ``NCHW4`` layout: ``{N, C/4, H, W, 4}``
* ``NCHW88`` layout: ``{N, C/8, H, W, 8}``
* ``CHWN4`` layout: ``{C/4, H, W, N, 4}``
