> Autotvm does this for external libraries which are all extern, so it will
work here
I like the idea of separating sorting based implementation of scatter, so I
want to try this. Can you point me where in the codebase autotvm deals with
external libs? I found something like
`@autotvm.register_topi_compute("conv2d_cudnn.cuda")` but I'm not sure how it
interacts with normal conv2d ops.
One issue is that currently sorting based approach is only implemented for
1D scatter. For higher dimensions, I think sorting based approach is a bad
idea. So dispatching decision needs to take input dimension into account (not
sure if this could be a problem for autotvm or relay strategy).
