In TVM, these has lots of operator which can not support int8 calculate such as mean and avg_pool2d. And take mean Op for example, the TVM will automatilly insert dequant and quant Op. And In graph optimization process, I will get the right result as show in pictures. However, In my mind, I think the left one will be the best graph optimization, because it has low memory access. So I wonder how to modify the graph optimization methods to generate the result as left.
