    hierarchy as the original eager module. This can be useful if you are trying
    to use :mod:`torch.export` with another system that expects a module
    hierachy instead of the flat graph that :mod:`torch.export` usually produces.

    .. note:: The args/kwargs of unflattened modules will not necessarily match
        the eager module, so doing a module swap (e.g. :code:`self.submod =
        new_mod`) will not necessarily work. If you need to swap a module out, you
        need to set the :code:`preserve_module_call_signature` parameter of
        :func:`torch.export.export`.

    Args:
        module (ExportedProgram): The ExportedProgram to unflatten.
        flat_args_adapter (Optional[FlatArgsAdapter]): Adapt flat args if input TreeSpec does not match with exported module's.

    Returns:
        An instance of :class:`UnflattenedModule`, which has the same module
        hierarchy as the original eager module pre-export.

    into copy_ nodes in the graph.

    Functionalization represents a buffer mutation by passing the buffer as
    an input and output. For example, consider the eager code:
        def forward(self, x):
            self.buffer += x
            return x * x

    This corresponds to a graph that looks like:
        def forward(self, buffer, x):
            mutated_buffer = aten.add(buffer, x)
            mul = aten.mul(x, x)
            return (mutated_buffer, mul)

    We want to inplace this into something that looks like the original
    eager code:
        def forward(self, buffer, x):
            mutated_buffer = aten.add(buffer, x)
            buffer.copy_(mutated_buffer)
            mul = aten.mul(x, x)
            return (mul,)

    Input mutations are handled similarly.

    Collect the intermediate values of mutations in a graph.

    Example: in the following graph, suppose that buf_in and buf_out
    are the input and output values of a buffer.

        buf_in = placeholder()
        ...
        ival1 = f0(buf_in, ...)  # inside self.n0(...)
        ...
        ival2 = f1(ival1, ...)  # inside self.n1(...)
        ...
        buf_out = f2(ival2, ...)  # inside self.n2(...)
        return buf_out, ...

    Here ival1 and ival2 are intermediate values created inside
    calls to n0 and n1 respectively, and used inside calls to
    n1 and n2 respectively.

    Exported modules are purely functional, so they pass their parameters and
    buffers in as inputs to the graph.

    To replicate eager's semantics, we need to get them from the module state
    via get_attr instead.

    module: GraphModule, potentially containing nested submodules.
    inputs_to_state: mapping graph input names to the corresponding key in the state_dict.
    scope: tracks where we are in the module hierarchy, so that we can emit the
        right `getattr(self, "foo.bar")` calls, etc.
    module_id_to_inputs_removed: records inputs removed by child modules, mapping
        the module object id to the list of placeholder node names in the child module
        that were removed.
