[Peeta586]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

There is not the dilation as an argument passed into build_kernel_map function, Is it right?

kmap = F.build_kernel_map(
                coords,
                feats.shape[0],
                kernel_size,
                stride,
                padding,
                hashmap_keys,
                hashmap_vals,
                spatial_range,
                kmap_mode,
                dataflow,
                downsample_mode=config.downsample_mode,
                training=training,
                ifsort=config.ifsort,
                split_mask_num=config.split_mask_num,
                split_mask_num_bwd=config.split_mask_num_bwd,
            )

Expected Behavior

I want to know how does the dilation work?
