环境是wsl的conda环境。
使用conda安装paddlepaddle-gpu:
conda install paddlepaddle-gpu==2.5.1 cudatoolkit=11.7 -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/Paddle/ -c conda-forge
等待安装...
报错处理：
(1)PreconditionNotMetError: Cannot load cudnn shared library. Cannot invoke method cudnnGetVersion.

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。
创建存放动态库的文件夹
mkdir /usr/local/cuda/lib64 -rf
拷贝动态库到lib
~/miniconda3/pkgs/cudatoolkit-11.7.0-hd8887f6_10/lib$ sudo cp * /usr/local/cuda/lib64 -rf
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
编辑 .bahsrc
vim ~/.bashrc
末尾添加
export LD_LIBRARY_PATH="/usr/local/cuda/lib64"
（2）The third-party dynamic library (libcuda.so) that Paddle depends on is not configured correctly.

Suggestions:
Check if the third-party dynamic library (e.g. CUDA, CUDNN) is installed correctly and its version is matched with paddlepaddle you installed.
Configure third-party dynamic library environment variables as follows:
Linux: set LD_LIBRARY_PATH by `export LD_LIBRARY_PATH=...`
Windows: set PATH by `set PATH=XXX;
C++ Traceback (most recent call last):
No stack trace in paddle, may be caused by external reasons.
Error Message Summary:
FatalError: `Segmentation fault` is detected by the operating system.

原因：paddel没有找到libcuda.so（标红）
解决：在~/.bashrc中加入环境变量
export LD_LIBRARY_PATH="/usr/lib/wsl/lib:$LD_LIBRARY_PATH"
vim ~/.bashrc
