add_quant_dequant
class torch.quantization.add_quant_dequant(module)
Wrap the leaf child module in QuantWrapper if it has a valid
   qconfig Note that this function will modify the children of module
   inplace and it can return a new module which wraps the input module
   as well.
Parameters:
      * module -- input module with qconfig attributes for all the
        leaf modules
  * **quantize** (*that we want to*) --

Returns:
      Either the inplace modified module with submodules wrapped in
      QuantWrapper based on qconfig or a new QuantWrapper module
      which wraps the input module, the latter case only happens when
      the input module is a leaf module and we want to quantize it.
