sod4onnx
Simple model output OP additional tools.
Decision gist · record as of 2026-08-14
No. While the tool is simple and has no install friction, it has been abandoned for nearly four years with no maintenance or updates. Compatibility with current ONNX versions is uncertain, and the lack of ongoing support makes it risky for production use. Consider alternatives that are actively maintained if you need reliable ONNX output deletion.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
sod4onnx is a lightweight utility for modifying ONNX model graphs by removing specified output operations. It provides both a command-line interface and a Python API (the `outputs_delete` function) to accept an ONNX model file or graph object, delete named outputs, and write the result back to disk or return it as a modified graph object.
The tool is designed for model optimization workflows where intermediate or unwanted outputs need to be pruned from a trained model before deployment. It has no runtime dependencies beyond Python itself, making installation friction minimal. However, the package has not been maintained since its initial release in September 2022, raising concerns about compatibility with newer ONNX specifications or Python versions.
Use it for
- Remove intermediate output layers from ONNX models before deployment to reduce model size or inference overhead.
- Prune unnecessary outputs from multi-output models to simplify downstream inference pipelines.
- Prepare ONNX models for edge deployment by stripping outputs not needed on target hardware.
- Automate ONNX graph cleanup in model conversion pipelines where intermediate outputs are generated but not used.
