众所周知，之前飞桨一直不支持ubuntu22.04,只有比较老旧的ubuntu18.04, 16.04等老系统。
今天为了部署，特意安装ubuntu系统，装完ubuntu18.04才赫然发现，已经支持CUDA11.7了，突然想到这个版本是支持ubuntu22.04的，随即立刻下载新版本ubuntu，重新再次安装。
总结，今天安装了2次ubuntu。
- ubuntu18.04 不自带显卡驱动，3060显卡下分辨率800*600很难搞。
- ubuntu22.04 默认情况下不支持我的博通网卡（当年为了黑苹果特意买的）
0.硬件情况
- 3060显卡一枚
- 9400cpu一枚
- 分区固态500Gb
- 其他硬件
1.安装前系统准备
- 装完系统，网卡不支持，通过手机USB网络共享上网（android系统自带）
- 点击软件及更新，设置更新源为 阿里源 ，估计更新速度会快
- 点击 “Additional Drivers”，选择nvidia-driver-520(proprietary)（英伟达显卡专用驱动）
- 此外，选择Broadcom Wireless Network Adapter(无线网卡驱动)
更新ing，持续4个多小时，我的小水管流量心疼啊。。。。。。
2.安装 miniconda
- 打开 tuna.moe 找到 miniconda ，下载并安装。
- 打开 tuna.moe/oh-my-tuna ，按指示操作换源（conda、pip）
3.安装 PaddlePaddle-GPU
打开 www.paddlepaddle.org.cn/ 官网，选择 conda、linux、2.4、cuda 11.7 。
3.1创建虚拟环境
首先根据具体的 Python 版本创建 Anaconda 虚拟环境，PaddlePaddle 的 Anaconda 安装支持 3.6 - 3.10 版本的 Python 安装环境。
conda create -n paddle_env python=YOUR_PY_VER
3.2 进入 Anaconda 虚拟环境
conda activate paddle_env
3.3 安装paddlepaddle-gpu=
- 对于
CUDA 11.7，需要搭配 cuDNN 8.4.1(多卡环境下 NCCL>=2.7)，安装命令为:
conda install paddlepaddle-gpu==2.4.0 cudatoolkit=11.7 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/
切记：
不要按照官网：
conda install paddlepaddle-gpu==2.4.0 cudatoolkit=11.7 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ -c conda-forge
操作，要删掉 -c conda-forge， 否则安装会特别慢，说不定还会中断，切记。。。。。。
4.排除bug操作
4.1 ImportError: libpython3.9.so.1.0: cannot open shared object file: No such file or directory
import paddle

处理办法：
如下所示，各位根据自己路径进行修改。

解决办法：根据命令所知，需要的cuda、cudnn都已经安装，出现这个问题是找不到对应的动态库，所以要针对性处理。
4.2.1 mkdir
创建存放动态库的文件夹
mkdir /usr/local/cuda/lib64 -rf
4.2.2 拷贝 cuda 的 lib
拷贝动态库到lib
~/miniconda3/pkgs/cudatoolkit-11.7.0-hd8887f6_10/lib$ sudo cp * /usr/local/cuda/lib64 -rf
4.2.3 拷贝 cudnn 的 lib
覆盖性拷贝，同手动安装cudnn操作
~/miniconda3/pkgs/cudnn-8.4.1.50-hed8a83a_0/lib$ sudo cp * /usr/local/cuda/lib64/ -rf
4.2.4 设置 LD_LIBRARY_PATH 环境变量
编辑 .bahsrc
gedit ~/.bashrc
末尾添加
export LD_LIBRARY_PATH="/usr/local/cuda/lib64"
5.安装完毕
