Ubuntu 14.04 CUDA 8.0未滿足依賴性

Question

我正在嘗試將自己的cuda庫升級為最新的Cuda 8.0.61。 我從刪除cuda 7.5開始。 稍后，我下載了cuda 8.0.61的deb文件並運行以下命令：

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

在安裝過程中，我收到一個錯誤，當我嘗試運行sudo apt-get install -f ，出現以下依賴項錯誤：

我不確定8.0.34的來源，但是現在我什么也不能安裝（我的意思是!!!），也無法刪除Cuda嗎？ 有什么建議嗎？

謝謝，

首先，您需要刪除舊的CUDA安裝：

sudo rm -r /usr/local/cuda*

然后，訪問NVIDIA網站並下載.run文件。

通過以下方式安裝：

sh cuda_8.0.27_linux.run --override

如果您打算進行一些深度學習，則可能還應該獲得CudNN文件：如果是這種情況，作為可選步驟，您可以通過進入提取的文件夾來安裝CudNN並執行以下操作：

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

接下來，在.bashrc中設置環境路徑變量：

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