Detailed Description

A class to represent an ONNX node that is not "accelerateable".

This node is created to preserve the original ONNX model graph structure, but will be skipped by the underlying engines, treating it as a 0 HW cost node.

Constructor & Destructor Documentation

__init__()

None __init__	(		self,
		int	node_id,
		list[int]	predecessors,
		str	node_type,
		str	node_name = ""
	)

Initialize the DummyNode by setting its id, the node's predecessors and optionally giving it a name.

Parameters

id	(int): id for this node
predecessor	(list): list of ids of this node's predecessor nodes
node_name	(str, optional): a name for this node, e.g. the node's name within the onnx model
