The external data is saved to os.path.join(basepath, location). Args: tensor: Tensor to be saved. name: Name of the tensor (i.e., initializer name in ONNX graph). location: Relative location of the external data file (e.g., "/tmp/initializers/weight_0" when model is "/tmp/model_name.onnx"). basepath: Base path of the external data file (e.g., "/tmp/external_data" while model must be in "/tmp").

Output files: ONNX model file path: ONNX initializer folder: os.path.join(basepath, initializer_location) After running this function, you can do ort_sess = onnxruntime.InferenceSession(os.path.join(basepath, model_location)) to execute the model. Arguments: basepath: Base path of the ONNX external data file (e.g., "/path/to/large_model/"). model_location: Relative location of the ONNX model file. E.g., "model.onnx" so that the model file is saved to "/model.onnx". initializer_location: Relative location of the ONNX initializer folder. E.g., "initializers" so that the initializers are saved to "/initializers/". Note: When initializers are >2GB, must be the same as `model_location`. torch_state_dicts: Dictionaries or files which contain PyTorch tensors to be saved as ONNX initializers. For non-dict arguments, `torch.load` will be used to load them from file-like objects. onnx_model: ONNX model to be saved with external initializers. If an input name matches a tensor loaded from "torch_state_dicts", the tensor will be saved as that input's external initializer. rename_initializer: Replaces "." by "_" for all ONNX initializer names. Not needed by the official torch.onnx.dynamo_export. This is a hack for supporting `FXSymbolicTracer` tracer with fake tensor mode. In short, `FXSymbolicTracer` lifts FX parameters (self.linear_weight) as inputs (`def forward(self, linear_weight)`) and therefore, `.` cannot be used. rNz .safetensorsrBT) map_locationmmapz+mmap can only be used with files saved withzFailed to load the checkpoint with memory-map enabled, retrying without memory-map.Consider updating the checkpoint with mmap by using torch.save() on PyTorch version >= 1.6.)rM._)reverse)!r enumerategraph initializerrinput isinstancedictr$endswithrKtorchload RuntimeError ValueErrorioBytesIOlogwarningseekr replacer*r&r'r(typer>popappendsortedrFsave)r2model_locationinitializer_locationtorch_state_dicts onnx_modelrename_initializerr initializers_to_be_deletedidxr7existing_initializersrUonnx_input_namesel state_dicterr1onnx_input_namerelative_tensor_file_pathmodel_input_typesr5s r=save_model_with_external_datarwtsN!#"+J,<,<,H,H"IQ 1;0@0@0F0FGu GGI> b$ J"c"r{{>'BA"E  "'BU!NJ',,.. >LD&! ||C-'' ''-'7O&//59W /(//@ )+ 5I4(P %:D9I9I9O9O PA P  P,,JN*+@+FGB)!%%dD1 L    ( ( / / =]. >7I>V"&)//14@"*..0.
