model.compile(jit_compile=True) for PyTorch has no intended effect (Keras 3.3)

[lseongjoo]

Description

When training a model in Keras 3.3 with the jit_compile=True option, a warning is displayed:

UserWarning: Model doesn't support `jit_compile=True`. Proceeding with `jit_compile=False`

PyTorch reports back its backends

assert torch.cuda.is_available()
torch.compiler.list_backends()
# ['cudagraphs', 'inductor', 'onnxrt', 'openxla', 'openxla_eval', 'tvm']

Investigation

Upon reviewing the source code, it appears that the jit_compile option is not implemented for PyTorch models. This feature might be planned but is not yet reflected in the code.

Steps to Reproduce

1. Define a model using PyTorch.
2. Compile the model with jit_compile=True.
3. Observe the warning during training.

Expected Behavior

The model should utilize jit_compile=True without warnings, or the documentation should clarify that this option is not supported for PyTorch models.

Environment

• Keras version: 3.3
• Backend: PyTorch 2.2

Additional Information

Please provide any updates on the planned implementation of jit_compile for PyTorch models or correct the documentation if this feature is not intended to be supported.

Hi for the API's or Layers which does not support XLA then the model will not proceed with jit_compile=True, it will instead fallback to jit_compile=False mode.
