当前环境中安装的 onnx 版本太高，而 RKNN-Toolkit2 v2.3.2 内部代码仍依赖旧版 ONNX 的 API（如 onnx.mapping），该 API 在新版 ONNX 中已被移除或重构。

确认当前 ONNX 版本

bash 复制代码 
/mnt/e/github/rknn_model_zoo/examples/yolov5/python$ python -c "import onnx; print(onnx.__version__)"
1.20.0

卸载当前 ONNX 并安装兼容版本

RKNN-Toolkit2 v2.3.x 官方推荐使用 ONNX 1.16.1

bash 复制代码 
pip uninstall onnx 
Found existing installation: onnx 1.20.0
