安装cv-cuda库，要求gcc11，cmake>3.22版本。

Linux distro:
    Ubuntu x86_64 >= 18.04
    WSL2 with Ubuntu >= 20.04 (tested with 20.04)
CUDA Driver >= 11.7 (Not tested on 12.0)
GCC >= 11.0
Python >= 3.7
cmake >= 3.22

升级完成之后报错，cuda不支持gcc，继续升级cuda。

升级cuda前需确认驱动版本是否匹配。
步骤1.查看所需的cuda版本（这里要求>= 11.7）
步骤2.去官网下载cuda，并查看对应的驱动版本，如果不满足需要升级nvidia驱动版本。
首先前往官网下载你需要升级的cuda版本的安装文件，官网下载地址：https://developer.nvidia.com/cuda-toolkit-archive
