onnx_diagnostic.torch_onnx.sbs¶
- onnx_diagnostic.torch_onnx.sbs.prepare_args_kwargs(torch_results: Dict[str, Any], node: Node) Tuple[Tuple[Any, ...], Dict[str, Any]][source][source]¶
Prepares args and kwargs before executing a fx node.
- Parameters:
torch_results – existing results
node – node to execute
- Returns:
new args and kwargs
- onnx_diagnostic.torch_onnx.sbs.run_aligned(ep: ExportedProgram, onx: ModelProto | FunctionProto, args: Tuple[Tensor, ...], check_conversion_cls: Dict[str, Any] | type, kwargs: Dict[str, Any] | None = None, verbose: int = 0) Iterator[Tuple[Any, ...]][source][source]¶
Runs in parallel both the exported program and the onnx proto and looks for discrepancies. The function does match on result names so it assumes the exported program and the onnx model have the same names for equivalent results.
- Parameters:
ep – exported program
onx – model or function proto
args – input args
check_conversion_cls – defines the runtime to use for this task
kwargs – input kwargs
verbose – verbosity level
- Returns:
a list of tuples containing the results, they come in tuple,
Example:
<<<

ExtendedReferenceEvaluator as ReferenceEvaluator, ) from onnx_diagnostic.torch_onnx.sbs import run_aligned class Model(torch.nn.Module): def forward(self, x): ry = x.abs() rz = ry.exp() rw = rz + 1 ru = rw.log() + rw return ru def post_process(obs): dobs = dict(zip(["ep_id_node", "onnx_id_node", "ep_name", "onnx_name"], obs)) dobs["err_abs"] = obs[-1]["abs"] dobs["err_rel"] = obs[-1]["rel"] return dobs x = torch.randn((5, 4)) Model()(x) # to make sure the model is running ep = torch.export.export( Model(), (x,), dynamic_shapes=({0: torch.export.Dim("batch")},) ) onx = torch.onnx.export( Model(), (x,), dynamic_shapes=({0: torch.export.Dim("batch")},), dynamo=True ).model_proto results = list( map( post_process, run_aligned( ep, onx, (x,), check_conversion_cls=dict(cls=ReferenceEvaluator, atol=1e-5, rtol=1e-5), verbose=1, ), ), ) print("------------") print("final results") df = pandas.DataFrame(results) print(df)
