[Question] how to block optimization pass in Relay

Questions
#1

Hello!

I know that “Relay Frontend” make graph optimization by using relay.transform.pass like FuseOps or ConstantFolding.

But I want to block all optimization pass for my experiment. So I adjusted “opt_level” when building “Relay” module like below.

with relay.transform.build_config( opt_level= 0 ):
    graph_json , Lib , Params = tvm.relay.build_module.build( mod , target='cuda' )

The mod have layers like below.

I want to build network without graph level optimization like the order above in my picture, but when i build module they automatically fuse some layer even when opt_level is zero.

So my question is if there are any function or options that can block all graph_level_optimization?
