It accepts either a file path to an .onnx model or an in-memory onnx.ModelProto object, locates a specified operator by name, and rewrites its attributes or the constants feeding into it. The tool operates on a single operator at a time and includes support for recursive modification within If operator subgraphs.\n\nThe package provides both a command-line interface and a Python API. It does not validate the overall graph integrity after modifications\u2014that responsibility falls to the user. It is designed for simple, targeted edits rather than comprehensive model transformation, making it useful for quick parameter adjustments, debugging, or preparing models for deployment with modified hyperparameters.","worth_installing":"Yes, if you need to edit ONNX operator parameters post-export. Low install friction, no dependencies, permissive license, and straightforward API make it a practical choice for model tweaking. Aging maintenance (189 days since last release) is a minor concern but not a blocker for a stable utility tool. Verify that graph-level side effects of your edits are acceptable before relying on it in production pipelines."},"id":"sam4onnx","links":{"html":"https://skillfed.io/packages/sam4onnx","md":"https://skillfed.io/packages/sam4onnx.md","pypi":"https://pypi.org/project/sam4onnx/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-02-06","license_spdx":null,"license_treatment":"permissive","name":"sam4onnx","python_support":"supports_current","summary":"A very simple tool to rewrite parameters such as attributes and constants for OPs in ONNX models.
