Hi Andrew. Though so many days passed, I’m still confused by this phenomenon. I have tried the latest version but it still crashed with Floating point exception (core dumped) on the statement graph, lib, params = relay.build(mod, target=‘llvm’). Could you please tell me the environment you install tvm on? I suspect different environments may have different outputs. Besides that, I think TVM is too strict to the occurence of “divide by 0”. Sometimes the computational graph is structrually correct but one variable , which is a divisor, may be assgined with 0 at runtime. This circumstance is possible but TVM will terminate and make the user confused and think the computational graph / network contains a problem.
