basic doubt

sir, can you please let me know, why have you use backward compatible code also in the implementation.
I am talking about the class defined below..
@staticmethod
def backward(ctx, grad_output):
assert grad_output.is_cuda

    .........

The forward of DDF is implemented in CUDA, the autograd is not suitable for this case. So, I also implement the backward function.

How can we relate applying dynamic concept (where every filter is applied to each pixel) with attention
