针对Linux虚机，当执行nvidia-smi命令验证驱动安装是否成功时，如果返回报错：
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
那么可以执行如下命令：
$ sudo nvidia-bug-report.sh然后在执行命令所在的路径查看日志文件，如在/tmp路径下执行的命令，那么查看日志文件：
$ less /tmp/nvidia-bug-report.log.gz从文件中可以查看到部分报错信息。
