问题：根据《Rockchip_User_Guide_RKNN_Toolkit_V1.7.1_CN》和 《Rockchip_Quick_Start_RKNN_Toolkit_V1.7.1_CN》操作文档已经安装了RKNN相关依赖，环境是python 3.7 (virtual)，pip3 install --default-timeout=100 rknn_toolkit-1.7.1-cp37-cp37m-linux_aarch64.whl
安装过程中就出现以下错误，大致是无法编译通过opencv-python，之前安装opencv-python 4.7版本，通过chat-gpt搜索答案后，重新安装opencv-python 4.5.3.56，仍然未解决！！！ 而且安装过程，不管是有线网还是无线网，等待非常久。
