Does TVM/Relay support Operator Decomposition?

Hi All,

I am wondering if TVM/Relay supports operator decomposition? Let us say you have a gaint 3Dconv, and I’d like to separate it into 2Dconv. What I mean is a kind of reverse of operator fusion in some sense.

  1. Is this currently supported by TVM?
  2. If not supported at this moment, is it even possible?
