Why there is no pytorch AOT graph tracer for both graph operations and bytecode

I see there are many options for model graph tracing including torch.export(), torch.compile() for jit execution and torch.compile.aot_compile(). torch.export(): Full AOT graph tracer but does not work with graph breaks. torch.compile(): Jit compiler works with graph breaks gives the controls to python interpreter for executing graph break bytecode at runtime. torch.compile.aot_compile(): AOT compilation on a torch.compile function raise error on graph break. I am curious why there is not a s...
