Recently I’m working on model quantization.
I have two goals:

multiply(int8_a, int8_b) >int8_c
====>saturate_multiply(int8_a, int8_b) > int8_c
. Making multiply operation in model to saturate multiply 
multiply(int8_a, float32_b) >int8_c
====>saturate_multiply(int8_a, float32_b) > int8_c
Which step is most appropriate for rewriting multiply
in relay > net.so
process.
Thanks.
