    您好，您的问题应该是库的版本问题，请检查一下您的onnx库的版本

    Code: Select all

    python -c "import onnx; print(onnx.__version__)"
    我实测1.17.0版本的可以运行，建议更改为该版本的onnx再尝试

    Code: Select all

    python -m pip uninstall -y onnx
conda remove onnx -y # 如果使用 conda 安装执行
python -m pip cache purge
python -m pip install --force-reinstall --no-cache-dir onnx==1.17.0

    发一下onnx，我试试
    我目前用的是:https://github.com/LuckfoxTECH/luckfox_ ... xample.git
    这个例子下面的 luckfox_pico_rknn_example/scripts/luckfox_onnx_to_rknn目录下面的例子
    (onnx就是model下面的yolov5)，
    也是官方网页https://wiki.luckfox.com/zh/Luckfox-Pico-Pi/RKNN给的例子，
    使用命令是python convert.py ../model/yolov5.onnx ../dataset/yolov5_dataset.txt ../model/yolov5.rknn Yolov5, 感谢大佬

    你好，请问修改onnx版本的话，需要修改onnxruntime版本吗?会有一些其他的影响吗

    您好，我目前使用您上诉给的命令去降级Onnx的版本，但是出现了错误，提示ERROR: Could not find a version that satisfies the requirement onnx==1.17.0 (from versions: none)
    ERROR: No matching distribution found for onnx==1.17.0，我之前的版本是onnx 1.19.0，请问现在还有什么办法解决吗?

    我conda环境用的python 是 Python 3.8.13，python 的版本也可能导致找不到指定的 python 包，不一定要指定 1.17.0 版本的其他低版本的也可以尝试
