   > I mean, If we did some constant folding optimization in the graph, and generate a new tensor which is not filled with same values. For example,
   > 
   > ```
   > scaled_weight = weight * scale, 
   > out = convolution(weight = scaled_weight)
   > ```
   > 
   > For this code, that scale multiply will execute many times during each iteration of inference. Because weight and scale are all constant, so we can fold them before inference, and use a constant node to replace the folded result in the graph. The value holding by constant node is vary, which can't be generated with simple pattern.
   
   which operator is currently used in this scenario?
