NVIDIA-SMI 找不到 libnvidia-ml.so 库

Question

我的笔记本电脑中有以下 Nvidia 显卡

ant@Anthill ~> lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
    Subsystem: Lenovo 4th Gen Core Processor Integrated Graphics Controller
    Kernel driver in use: i915
--
07:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 740M] (rev a1)
    Subsystem: Lenovo GK208M [GeForce GT 740M]
    Kernel modules: nvidiafb, nouveau

我已通过以下方式安装驱动程序

sudo apt-add-repository ppa:graphics-drivers/ppa
sudo apt-get install nvidia-370 nvidia-prime

和 cuda 工具包通过从 nvidia 官方网站下载 cuda-7.5 二进制文件

sudo ./NVidia-cuda-7.5.run

所有这些安装都是在转移到tty并停止 XOrg 之后完成的

sudo service lightdm stop

现在重启后

ant@Anthill ~> nvidia-smi
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.

libnvidia-ml.so存在于此处

libGL.so.1.0.0                 libnvidia-encode.so.370.28

我也尝试将此目录添加到 PATH 和 LD_LIBRARY_PATH 中。两者都不起作用。

还，

ls /dev | grep nvidia

一无所获。那是没有设备存在/dev/nivida*

有什么建议可以让这个工作吗？在哪里nvidia-smi尝试找到libnvidia-ml.so？

Answer 1

LD_PRELOAD=/usr/lib/nvidia-367/libnvidia-ml.so nvidia-smi
