更换清华源

打开清华源官网，搜索对应系统版本的镜像源码

https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/

原文件备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

编辑源文件

sudo gedit /etc/apt/sources.list

将原来内容删除，添加清华源源码

安装TensorRT

查看和CUDA对应的版本tensorrt cuda版本对应_tensorrt和cuda版本对应-CSDN博客

安装过程是在conda虚拟环境中进行，所以需要提前安装好anaconda并激活虚拟环境，这里对虚拟环境的python有要求，需要安装tensorrt/python文件中包含的python版本；

本文安装的是cuda11.7+cudnn8.9.4.25+python3.7的虚拟环境+TensorRT8.4.3.1；

安装过程参考【Ubuntu版】TensorRT安装教程（tar包方式）_ubuntu安装tensorrt-CSDN博客

文中添加环境参考下文

gedit ~/.bashrc# 添加#TensorRT
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/user/software/TensorRT-8.4.3.1/lib
export PATH=$PATH:/home/user/software/TensorRT-8.4.3.1/bin
export LD_LIBRARY_PATH=/home/user/software/TensorRT-8.4.3.1/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=/home/user/software/TensorRT-8.4.3.1/lib:$LIBRARY_PATH# 更新
source ~/.bashrc
