class torch.quantization.propagate_qconfig_(module, qconfig_dict=None, prepare_custom_config_dict=None)
Propagate qconfig through the module hierarchy and assign qconfig
   attribute on each leaf module
Parameters:
      * module -- input module
  * **qconfig_dict** -- dictionary that maps from name or type of
    submodule to quantization configuration, qconfig applies to
    all submodules of a given module unless qconfig for the
    submodules are specified (when the submodule already has
    qconfig attribute)

  * **prepare_custom_config_dict** -- dictionary for custom
    handling of modules see docs for "prepare_fx()"
