按照Nvidia官网的指南安装了最新版本的cuda13的过程如下：
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2404/x86_64/cuda-ubuntu2404.pin
sudo mv cuda-ubuntu2404.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/13.0.2/local_installers/cuda-repo-ubuntu2404-13-0-local_13.0.2-580.95.05-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2404-13-0-local_13.0.2-580.95.05-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2404-13-0-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda
然后发现都安装好了，但nvcc不能用，提示找不到：

(base) hope@station:~$ nvcc --version
Command 'nvcc' not found, but can be installed with:
sudo apt install nvidia-cuda-toolkit
(base) hope@station:~$
其实这就是环境变量没有设置的问题，在.bashrc文件中添加如下内容：
echo 'export PATH=/usr/local/cuda-13.0/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda-13.0/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc
然后就可以用nvcc了：
(base) hope@station:~$ nvcc --version
