-> **⚠️ Deprecated**: `to_torchscript()` is deprecated in PyTorch Lightning v2.5 and will be removed in v2.7.
-> TorchScript is deprecated in PyTorch. Use `torch.export.export()` instead.
-> See [PyTorch Export Documentation](https://pytorch.org/docs/stable/export.html) for more information.

-```python
-# torchscript (deprecated)
-autoencoder = LitAutoEncoder()
-torch.jit.save(autoencoder.to_torchscript(), "model.pt")
-
-# Recommended alternative using torch.export
-import torch
-autoencoder = LitAutoEncoder()
-exported_program = torch.export.export(autoencoder, (torch.randn(1, 64),))
-torch.export.save(exported_program, "model.pt2")
