Ubuntu 14.04 CUDA 8.0 未满足的依赖

Question

我正在尝试将我的 cuda 库升级到最新的 Cuda 8.0.61。 我从删除 cuda 7.5 开始。 后来我下载了cuda 8.0.61的deb文件并运行以下命令：

1. sudo dpkg -i cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64.deb
2. sudo apt-get update
3. sudo apt-get install cuda

在安装过程中我收到一个错误，当我尝试运行 sudo apt-get install -f 时，我收到以下依赖错误：

The following packages have unmet dependencies:

我不确定 8.0.34 是从哪里来的，但现在我无法安装任何东西（我的意思是任何东西！！！）而且我无法删除 Cuda？ 有什么建议吗？

谢谢，

首先，您需要删除 CUDA 的旧安装：

sudo rm -r /usr/local/cuda*

然后，访问 NVIDIA 网站并下载 .run 文件。

安装它：

sh cuda_8.0.27_linux.run --override

如果您打算进行一些深度学习，您可能还应该获得 CudNN 文件： 如果是这种情况，作为可选步骤，您可以通过进入提取的文件夹并执行以下操作来安装 CudNN：

sudo cp lib64/* /usr/local/cuda/lib64/
sudo cp include/* /usr/local/cuda/include/

接下来，在.bashrc中设置环境路径变量：

export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
