.torch_interpreter.oxs_dispatcher

class experimental_experiment.torch_interpreter.oxs_dispatcher.OxsDebugDispatcher(verbose: int = 0, raise_exc: bool = True)

Tries the fallback even if is not necessary to check it is working.

Parameters:

• verbose – verbosity

• raise_exc – fail or raise an exception

The class can be used the following way.

fallback(name: Any, fct: Callable | None, args: List[Any], kwargs: Dict[str, Any], builder: GraphBuilder) → Callable | None

The function is called after the function converting an aten function into ONNX. fct is this function. It can be changed and just set when mapping was found.

Parameters:

• name – object or str

• fct – function found so far

• args – known arguments coming from the graph module

• kwargs – known named arguments coming from the graph module

• builder – GraphBuilder

Returns:

callable

class experimental_experiment.torch_interpreter.oxs_dispatcher.OxsDispatcher(verbose: int = 0)

If DynamoInterpreter cannot find any converting function for a specific function, it tries to find an existing one in onnxscript. The converting function from onnxscript is run in trace only mode. The variable and functions op, Rank, IsScalar are replaced by op = OwsOpset(), op.Rank, op.Scalar. onnxscript may have multiple overloaded functions. Right now, it takes the first one.

Parameters:

verbose – verbose

fallback(name: Any, fct: Callable | None, args: List[Any], kwargs: Dict[str, Any], builder: GraphBuilder) → Callable | None

The function is called after the function converting an aten function into ONNX. fct is this function. It can be changed and just set when mapping was found.

Parameters:

• name – object or str

• fct – function found so far

• args – known arguments coming from the graph module

• kwargs – known named arguments coming from the graph module

• builder – GraphBuilder

Returns:

callable

property submodules: Dict[str, Callable]

Returns the submodules implementing torch functions.
