linux c++ 开发 tensorrt 安装

tensorrt 官方下载地址（需要注册账号登录）：Log in | NVIDIA Developer

根据系统发行版和CUDA版本 (nvcc -V) 选择合适的安装包

EA（early access）版本代表抢先体验。

GA（general availability）代表稳定版，经过全面测试。

建议选用 TensorRT 最新版本的 GA release

为了不影响系统环境，只进行单个 C++ 项目的开发，这里选用 TAR Package，解压即用，无需安装。

tar -zxvf TensorRT-8.6.1.6.Linux.x86_64-gnu.cuda-11.8.tar.gz
