class_docstr: Change `batch_stat` to `False`.
  Supported functions: `BatchNormalization`, `FusedBatchNormalization`, `SyncBatchNormalization`.
  
  Examples:
  
  .. code-block:: python
  
     pred = Model(...)
  
     import nnabla.experimental.graph_converters as GC
  
     modifiers = [GC.BatchNormBatchStatModifier()]
     gc = GC.GraphConverter(modifiers)
     pred = gc.convert(pred)

      if not f.info.type_name in self._fct_set:
          return
  
      h = self.connect(f.info.type_name, inputs, f.info.args)
  
      return h

label_desc: Use image node_id 3 for calling the BatchNormBatchStatModifier obj's underlying member method code with example usage: obj.modify(f, inputs) and returns: h
