Detailed Description

An interpreter for Relay.

This file implements a simple reference interpreter for Relay programs. Given a Relay module, and a Relay expression it produces a value.

The interpreter's values are a naive representation of the values that can be produced by a Relay program and are exposed via TVM's object protocol to Python for introspection and debugging.

The interpreter's intent is to serve as a reference semantics for the Relay IR, as well as for debugging and testing.
