Can we calculate FLOP of exported model

Questions
1

I see in the AutoTVM have calculate FLOP for each autotvm.task.Task. I also can get variable flop for each task.

However, I have a question about How can we get the overall FLOP of the compiled model after we export it to .so file?

I guess the FLOP, may different than before because I see some operation be fused. (as I see from json file it have many fused function)

Thank you!
