NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
安装完 GPU 的驱动并重启系统后，执行 nvidia-smi 报错:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running. |
执行 nvidia-settings，报错:
|
1 2 |
ERROR: NVIDIA driver is not loaded ERROR: Unable to load info from any available system |
通过 lspci 可以看到系统识别了显卡：
|
1 2 |
[root@localhost ~]# lspci | grep -i nvidia d8:00.0 3D controller: NVIDIA Corporation GV100GL [Tesla V100 PCIe 16GB] (rev a1) |
执行 dkms status 发现已经安装驱动:
|
1 2 |
dkms status nvidia, 430.50: added |
解决办法：
有人说内核版本冲突，也有执行nvcc -V命令的。可是我安装的包是匹配的内核版本，执行nvcc提示找不到命令。通过 nvidia-smi 报错提示发现需要我需要确认驱动是否已经安装并运行，因为之前自己确实做了一些列操作，驱动安装了肯定没问题，只是不确定是否安装正确，第二个是如果安装了驱动有没有加载到内核运行。通过dkms发现驱动模块已经添加。
1）查询当前使用的 nvidia 驱动 版本号
|
1 2 |
# [root@localhost ~]# ls /usr/src | grep nvidia nvidia-440.95.01 |
2）重新安装驱动（根据个人实际的版本号填写，上一步的输出）
|

dkms install -m nvidia -v 440.95.01 |

顺着下来，一切正常，但是这里显示已经安装了。但是还是不能用
