Is it possible to convert a script module to trace with dummy input tensors. I tried with code
model=torch.jit.load('model.pt')
dummy=torch.rand((1,3,224,224))
traced=torch.jit.trace(model,dummy)

Following warning was thrown:
UserWarning: The input to trace is already a ScriptModule, tracing it is a no-op. Returning the object as is.
