NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
the nvidia bug report starts off with a bunch of failed conftests:
#error acpi_walk_namespace() conftest failed!

答案1
我的猜测是：您用版本 5.5 替换了默认的 gcc 编译器（8.4？），结果出乎意料的是，Nvidia 驱动程序不再成功编译。
假设您确实需要 Nvidia 驱动程序 455（标准 Ubuntu 存储库尚未提供），并且驱动程序构建在 Ubuntu 上确实有效，请撤消 gcc 上的替代方案，使用名为 gcc、g++、ar、ranlib 等的链接指向 ...CUDA/bin 目录中的旧版本（该目录应位于 PATH 中的第一个）。
使用正确版本的系统 gcc，至少 Nvidia 驱动程序应该能够工作。
要覆盖用于 CUDA 工作的 gcc，而不更改系统用于更新视频模块等内容的内容，请参阅
运行向量加法的 cuda 示例程序的步骤？
以下是相关段落的摘录：
首先阅读 CUDA 安装指南中的 Ubuntu 部分：例如https://docs.google.com/viewer?url=https%3A%2F%2Fdocs.nvidia.com%2Fcuda%2Fpdf%2FCUDA_Installation_Guide_Linux.pdf&pdf=true
第 6 章中关于设置环境变量 PATH 和 LD_LIBRARY_PATH 的建议表明，您的 cuda 添加应该位于现有 PATH 的开头。这样，您只需将 ...cuda/bin 的链接添加到所需版本，即可用旧版本覆盖系统 g++ 或 gcc。您最不想做的事情就是更改系统默认编译器——当内核更新时，该编译器可能无法成功更新您的视频驱动程序。如果您所做的一切都可能使用旧编译器，请继续修改 .profile 中的 PATH 设置，以便每次登录时都设置您的 cuda 路径。如果您只希望 CUDA 工作使用旧编译器，请将 PATH、LD_LIBRARY_PATH 修改放入脚本中，以便在需要时进行源代码处理。
