先卸载原有opencv（卸载干净 pip uninstall opencv-python）,然后打开Ubuntu终端，查看环境为anaconda，环境为base，然后激活base（conda activate base），重新安装pip install opencv-python==version,后再pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip -U(直接安装会报错)，再pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip install opencv-python==version，报错解决
