  //     { "/google/nn", { ... }},
  //     { "/google/vision", { ... }}

  //     node[i] is deemed as a function call. Otherwise, node[i].op
  //     must be a primitive operation supported by the runtime.
  //
  //
  // Function call semantics:
  //
  //   * The callee may start execution as soon as some of its inputs
  //     are ready. The caller may want to use Tuple() mechanism to
  //     ensure all inputs are ready in the same time.
  //
  //   * The consumer of return values may start executing as soon as
  //     the return values the consumer depends on are ready.  The
  //     consumer may want to use Tuple() mechanism to ensure the
  //     consumer does not start until all return values of the callee
  //     function are ready.
