最近新安装了ubuntu22.04，下载推荐显卡驱动570

下面这个连接下载cuda11.8

CUDA Toolkit 11.8 Downloads | NVIDIA Developer

执行下面两句后 

wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run
sudo sh cuda_11.8.0_520.61.05_linux.run

出现正常安装的界面

但是输入nvcc-V出现：

 nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Thu_Nov_18_09:45:30_PST_2021
Cuda compilation tools, release 11.5, V11.5.119
Build cuda_11.5.r11.5/compiler.30672275_0

解决办法：

sudo apt-get install nvidia-cuda-toolkit
sudo apt-get autoremove nvidia-cuda-toolkit
nvcc -V
sudo gedit ~/.bashrc

末尾添加：

export PATH=$PATH:/usr/local/cuda-11.8/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.8/lib64
export CUDA_HOME=/usr/local/cuda-11.8
