Simple node addition tool for onnx. Simple Node Addition for ONNX.

sna4onnx

Simple node addition tool for onnx. Simple Node Addition for ONNX.

https://github.com/PINTO0309/simple-onnx-processing-tools

Key concept

• Combines the OP generated by sog4onnx with the specified output and input OPs.
• Use a good combination with the ONNX merge tool snc4onnx while merging OP parts.
• Only one OP can be extrapolated at a time.
• After OP extrapolation, the entire model is checked, and even if there is a consistency problem, only a warning is displayed and the ONNX file is output as is.
• Add unconnected input and output variables to the input/output OP of a graph.
