class_docstr: Context of converter
  
  This context shares names during exporting.
  
  Attributes:
      name_list (dict): list of being exported as ONNX node name with pinned
          or not, keyed by instance ID. When the target variable is
          ``chainer.Variable`` or ``chainer.Parameter``, instance ID of
          ``ndarray`` held by the variable is also put as key, because some
          functions like ``F.where`` internally unwrap variable.
