linux - 无法插入 'nvidia_352' : No such device

Question

我正在尝试运行 caffe在 Linux Ubuntu 上。安装后在gpu中运行caffe报错

I0910 13:28:13.606891 10629 caffe.cpp:296] Use GPU with device ID 0

我的 NVIDIA 驱动程序是 352.41。我安装了 352，它安装的是最新版本。

sudo apt-get install nvidia-352[sudo]

我的 Ubuntu 有 NVIDIA 驱动程序 352 以及为什么我有这样的错误

I0910 13:28:13.606891 10629 caffe.cpp:296] Use GPU with device ID 0

我检查了我是否有支持 CUDA 的设备，例如

lspci | grep -i nvidia
05:00.0 VGA compatible controller: NVIDIA Corporation GK107GL [Quadro K2000] (rev a1)
05:00.1 Audio device: NVIDIA Corporation GK107 HDMI Audio Controller (rev a1)

我有支持 CUDA 的设备，为什么会出现错误？

编辑 1:是的，我对 ./deviceQuery 的测试失败了。

../NVIDIA_CUDA-7.5_Samples/bin/x86_64/linux/release/deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 38
-> no CUDA-capable device is detected
Result = FAIL

我检查了 dev/文件夹，我有 nvidia0。

crwxrwxrwx  1 root root    195,   0 Sep 10 16:51 nvidia0
crw-rw-rw-  1 root root    195, 255 Sep 10 16:51 nvidiactl

我的 nvcc -V 检查给了我

li@li-HP-Z420-Workstation:/dev$ nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

然后我的版本检查

li@li-HP-Z420-Workstation:/dev$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  352.41  Fri Aug 21 23:09:52 PDT 2015
GCC version:  gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04) 

有什么问题吗？

Answer 1

现在问题解决了。我检查了 sudo dpkg --list | grep nvidia我发现我的内核有 352.41，但客户端有 304.12。所以我做了 sudo apt-get remove --purge nvidia-*。它删除了所有包。然后，将 352.41 安装为

$ sudo add-apt-repository ppa:xorg-edgers/ppa -y
$ sudo apt-get update
$ sudo apt-get install nvidia-352

之后

$ sudo dpkg --list | grep nvidia
rc nvidia-304 304.128-0ubuntu0~gpu14.04.2 amd64 NVIDIA legacy binary driver - version 304.128
rc nvidia-304-updates 304.125-0ubuntu0.0.2 amd64 NVIDIA legacy binary driver - version 304.125
ii nvidia-352 352.41-0ubuntu0~gpu14.04.1 amd64 NVIDIA binary driver - version 352.41
rc nvidia-opencl-icd-304 304.128-0ubuntu0~gpu14.04.2 amd64 NVIDIA OpenCL ICD

ii nvidia-prime 0.6.2 amd64 Tools to enable NVIDIA's Prime
ii nvidia-settings 355.11-0ubuntu0~gpu14.04.1 amd64 Tool for configuring the NVIDIA graphics driver

现在版本匹配。然后 ./deviceQuery 和所有按预期工作。谢谢
