Thanks @mshr-h , we are moving more towards relax based pipeline whose tests won't depends on running the code, which has increasing pressure on the ci. Would be great to bring support for relax

Thank you for your comment, @tqchen. I understand the relax development. However, our internal ML compiler still relies on Relay, so continued support would benefit us. I'll also bring support for relax later. BTW, support for aten::tile is needed for compiling Segment Anything 2 from Meta.
