Can you give an example of how to call this function? I get the following error:
TypeError: backward(): incompatible function arguments. The following argument types are supported:
1. (arg0: at::IntArrayRef, arg1: at::Tensor, arg2: at::Tensor, arg3: at::IntArrayRef, arg4: at::IntArrayRef, arg5: at::IntArrayRef, arg6: int, arg7: bool, arg8: bool) -> at::Tensor
