Fixes #7497
Summary
Users hit a confusing error when loading a PyTorch model into the LibTorch backend:
This happens when the supplied
model.ptis not a TorchScript artifact (for example an eager-mode module or a barestate_dictsaved withtorch.save). The current docs do not explain this requirement, so the error is hard to diagnose.Changes
docs/user_guide/model_repository.md: add a note to the TorchScript Models section explaining thatmodel.ptmust be produced withtorch.jit.script()/torch.jit.trace()andtorch.jit.save(), shows the exact error users see when it is not, and tells them how to fix it.Notes
