class_docstr: This allows us to use a list of `TransformModule` in the same way as
  :class:`~torch.distributions.transform.ComposeTransform`. This is needed
  so that transform parameters are automatically registered by Pyro's param
  store when used in :class:`~pyro.nn.module.PyroModule` instances.
code: def __hash__(self):
      return super(torch.nn.Module, self).__hash__()

label_desc: Use image node_id 2 for calling the ComposeTransformModule obj's underlying member method code with example usage: obj.__hash__() and returns: super
