No, and it is strongly advised that you keep your source code around when doing stuff with JITed models.
That said, you can probably get a reduced model by walking the traced module, setting the children in init and using the .forward of each module.
This would get you something you can run and re-trace, but you loose how it was built (i.e. the inits).
Fun fact: In building a PyTorch-TVM bridge 2 I built a PyTorch autograd function (but with TVM as backend instead of calling PyTorch) corresponding to the traced model.
