ERROR: Could not build wheels for onnx, which is required to install pyproject.toml-based projects

pip3 install -r requirements.txt 安装需求文件时提示错误: ERROR: Could not build wheels for onnx, which is required to install pyproject.toml-based projects

原因

python 版本太高, 和 onnx 的版本不兼容

解决

再重新下载一个低版本的python, 然后修改一下环境变量即可. 比如我把python-3.12改为python-3.11就可以了
