[Relay] analysing of relay graph and clone subggraphs

Questions
#1

Hi everyone,

I would like to iterate over relay graph and clone of interesting subgraphs as separate relay graphs. Will appreciate for any help and references to API or demo/snippets

You can use the dataflow matching API to extract sub-graphs which match a pattern. @mbrookhart probably knows where the most up to date docs are.

Docs are here. If you have more detail about what you’d like to do, we might be able to point you at something more specific.
