本文详细介绍了如何在Ubuntu 20.04（内核5.4.0-47-generic）上安装Nvidia驱动450和CUDA 11.0的过程。提供了两种方法：单独安装Nvidia驱动和CUDA工具包，以及通过CUDA工具包安装Nvidia驱动。重点强调了注意Linux内核、Ubuntu、Nvidia和CUDA版本的兼容性。

Totally,I have spend almost 4-5 days for this procedure.

There is two way to install cuda and nvidia.

1\ seperate the installation of Nvidia Driver and CUDA toolkit.

Because CUDA toolkit contains Nvidia Driver installation,so if you have installed Nvidia Driver before you are going to install CUDA,you need to unintall Driver or unselect the "Driver" in the CUDA Installation procedure.What i recommend is unselect it .

As mentioned in this blog:https://www.pugetsystems.com/labs/hpc/How-To-Install-CUDA-10-1-on-Ubuntu-19-04-1405/

after install CUDA without Driver selected,you need to set PATH environment.

I choose to append this three lines to ~/.bashrc:

export PATH=$PATH:/usr/local/cuda-11.0/bin
export CUDADIR=/usr/local/cuda-11.0
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.0/lib64
