class_docstr: GraphModule is an nn.Module generated from an fx.Graph. Graphmodule has a
  ``graph`` attribute, as well as ``code`` and ``forward`` attributes generated
  from that ``graph``.
  
  .. warning::
  
      When ``graph`` is reassigned, ``code`` and ``forward`` will be automatically
      regenerated. However, if you edit the contents of the ``graph`` without reassigning
      the ``graph`` attribute itself, you must call ``recompile()`` to update the generated
      code.
