Meaning of options:
"linalg": run through torch-mlir"s default Linalg-on-Tensors backend.
"tosa": run through torch-mlir"s default TOSA backend.
"stablehlo": run through torch-mlir"s default Stablehlo backend.
"native_torch": run the torch.nn.Module as-is without compiling (useful for verifying model is deterministic; ALL tests should pass in this configuration).
"torchscript": compile the model to a torch.jit.ScriptModule, and then run that as-is (useful for verifying TorchScript is modeling the program correctly).
"lazy_tensor_core": run the model through the Lazy Tensor Core frontend and execute the traced graph.
"torchdynamo": run the model through the TorchDynamo frontend and execute the graph using Linalg-on-Tensors.
"onnx": export to the model via onnx and reimport using the torch-onnx-to-torch path.
"fx_importer": run the model through the fx importer frontend and execute the graph using Linalg-on-Tensors.
"fx_importer_stablehlo": run the model through the fx importer frontend and execute the graph using Stablehlo backend.
