I connect a graph compile, it reports waring

Help ~~ please

Not very clear where to put compile and how to use it. the resttransform not update

A graph doesn't need to be compiled until you need to invoke it. Even then, I think if a graph happens to not be compiled yet, the invoke will do a compile if missing. It's not clear from the snippet what you're trying to do there so please provide a simple example scene file if you're still struggling.
