Linux18.04中安装cuda

在Linux 18.04中安装CUDA，可以按照以下步骤进行操作。首先，下载CUDA的本地安装包并安装：

wget https://developer.download.nvidia.com/compute/cuda/10.1/Prod/local_installers/cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1804-10-1-local-10.1.243-418.87.00_1.0-1_amd64.deb

然后，添加密钥并更新apt-get：

sudo apt-key add /var/cuda-repo-10-1-local-10.1.243-418.87.00/7fa2af80.pub
sudo apt-get update

接下来，安装CUDA：

sudo apt-get -y install cuda

此外，你还需要将解压出来的CUDA目录下的include和lib64文件夹中的文件复制到/usr/local/cuda-10.1下的include和lib64目录，并设置权限：

sudo cp cuda/include/cudnn.h /usr/local/cuda-10.1/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda-10.1/lib64
sudo chmod a+r /usr/local/cuda-10.1/include/cudnn.h /usr/local/cuda-10.1/lib64/libcudnn*

完成以上步骤后，你就成功地在Linux 18.04中安装了CUDA。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
