flytekitplugins.onnxtensorflow.TensorFlow2ONNXConfig#

class flytekitplugins.onnxtensorflow.TensorFlow2ONNXConfig(input_signature, custom_ops=None, target=None, custom_op_handlers=None, custom_rewriter=None, opset=None, extra_opset=None, shape_override=None, inputs_as_nchw=None, large_model=False)[source]#

TensorFlow2ONNXConfig is the config used during the tensorflow to ONNX conversion.

Parameters

  • input_signature (Union[tensorflow.python.framework.tensor_spec.TensorSpec, numpy.ndarray]) – The shape/dtype of the inputs to the model.

  • custom_ops (Optional[Dict[str, Any]]) – If a model contains ops not recognized by ONNX runtime, you can tag these ops with a custom op domain so that the runtime can still open the model.

  • target (Optional[List[Any]]) – List of workarounds applied to help certain platforms.

  • custom_op_handlers (Optional[Dict[Any, Tuple]]) – A dictionary of custom op handlers.

  • custom_rewriter (Optional[List[Any]]) – A list of custom graph rewriters.

  • opset (Optional[int]) – The ONNX opset number.

  • extra_opset (Optional[List[int]]) – The extra ONNX opset numbers to be used by, say, custom ops.

  • shape_override (Optional[Dict[str, List[Any]]]) – Dict with inputs that override the shapes given by tensorflow.

  • inputs_as_nchw (Optional[List[str]]) – Transpose inputs in list from nhwc to nchw.

  • large_model (bool) – Whether to use the ONNX external tensor storage format.
