我正在尝试使用以下指南在 Ubuntu 18.04 上安装 CUDA 10.1
https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html
在步骤中7.2.1 Install Persistence Daemon，当我执行命令时
/usr/bin/nvidia-persistenced --verbose
我收到一个错误：
$ /usr/bin/nvidia-persistenced --verbose nvidia-persistenced failed to initialize. Check syslog for more details.
来自 /var/log/syslog 文件的日志：
May 27 19:49:42 Azurite nvidia-persistenced: Verbose syslog connection opened

我的 CUDA Toolkit 安装有问题吗？谢谢。在日志应用程序中：
Sender: nvidia-persiste
Message: Failed to lock PID file: Resource temporarily unavailable
当我和sudo

笔记：我的笔记本电脑7.2.3.3. Running the Binaries坏deviceQuery了bandwidthTest
答案1
我刚刚检查了使用htop，发现有一个正在运行PID 1304。Command /usr/bin/nvidia-persistenced --user nvidia-persistenced --no-persistence-mode --verbose我想一切都没问题，谢谢。
