Args: dynamic (`bool`, *optional*, defaults to `False`): Whether to export with dynamic (symbolic) shapes. When `True` and `dynamic_shapes` is not set, all tensor dimensions are set to `Dim.AUTO` automatically. strict (`bool`, *optional*, defaults to `False`): Whether to enable strict mode in `torch.export`. Runs the full symbolic trace and catches more errors, but is slower and more likely to fail on complex models. dynamic_shapes (`dict[str, Any]`, *optional*): Explicit per-input dynamic shape specifications passed to `torch.export`. Takes precedence over `dynamic`. prefer_deferred_runtime_asserts_over_guards (`bool`, *optional*, defaults to `False`): When `True`, data-dependent shape guards are emitted as runtime asserts in the exported graph instead of failing the export at trace time when a guard wouldn't hold across the full symbolic shape range. Most transformer LLMs need this set to `True` when using fine-grained ``Dim(min=, max=)`` bounds. Not needed with ``dynamic=True`` / ``Dim.AUTO``, where ``torch.export`` infers shape relations instead of verifying them against the user-stated bounds. rFdynamicstrictNdynamic_shapes+prefer_deferred_runtime_asserts_over_guards)rrrrr rrr+r1boolr2r3r-r.rr4rrrr0r0Ks0#/"5M<555GTFD,0NDcNT)0008=/=====rr0ceZdZUdZejZeed<dZe e zdzed<dZ e e e fdzed<dZedzed<dZeed<dZeed <dZeed <d Zeed <dS) OnnxConfigu> Configuration class for exporting models to ONNX via `torch.onnx.export`. Inherits all fields from [`DynamoConfig`] (`dynamic`, `strict`, `dynamic_shapes`, `prefer_deferred_runtime_asserts_over_guards`). Args: output_path (`str` or `PathLike`, *optional*): Output path for the `.onnx` file. When `None` (default) the exported model is kept in memory as an `ONNXProgram` and not written to disk. opset_version (`int`, *optional*): ONNX opset version to target. Defaults to the latest opset supported by the installed `onnxscript` version. external_data (`bool`, *optional*, defaults to `True`): Store large weight tensors in a separate `.onnx_data` sidecar file instead of embedding them in the protobuf. Required for models whose weights exceed the 2 GB protobuf limit. optimize (`bool`, *optional*, defaults to `True`): Run `onnxscript` optimisation passes (constant folding, dead-code elimination, …) on the exported graph. Disable for models that hit upstream `onnxscript` optimiser bugs. export_params (`bool`, *optional*, defaults to `True`): Embed model weights in the ONNX graph. Set to `False` to export a weight-free graph (weights must be supplied at runtime). keep_initializers_as_inputs (`bool`, *optional*, defaults to `False`): Expose weight initializers as explicit graph inputs. Required by some older ONNX runtimes (opset < 9). rN output_pathr3 opset_versionT external_dataoptimize export_paramsFkeep_initializers_as_inputs)rrrrr rrr+r8r.rr3r-rr9intr:r5r;r<r=rrrr7r7ms<#/"3M<333)-Kx$&---,0NDcNT)000 $M3:$$$M4HdM4(------rr7c:eZdZUdZejZeed<dZe ed<dS)ExecutorchConfigu Configuration class for exporting models to ExecuTorch format.
