“libnvidia-compute-435”软件包安装不完整，导致无法使用

我已经使用 GUI 安装了 NVIDIA 驱动程序版本 435：

在此处输入图片描述

我现在看到一个包裹列表：

我对 OpenCL 很感兴趣，所以我找到了 NVIDIA 软件包，它提供了与 OpenCL 相关的文件 - 就是这个libnvidia-compute-435软件包。它包含以下文件：

hekto@lynx:~$ dpkg -L libnvidia-compute-435
/.
/etc
/etc/OpenCL
/etc/OpenCL/vendors
/etc/OpenCL/vendors/nvidia.icd
/usr
/usr/lib
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/libcuda.so.435.21

/usr/lib/x86_64-linux-gnu/libnvidia-ptxjitcompiler.so
/usr/lib/x86_64-linux-gnu/libnvidia-ptxjitcompiler.so.1

文件/etc/OpenCL/vendors/nvidia.icd 是在这个列表中，但是它不存在在我的系统上。所有 OpenCL 程序都需要 ICD 文件，没有这些文件，它们就无法找到特定于供应商的库。

那么，为什么这个文件不存在？为什么apt没有安装所有需要的文件？

（我使用的是 Xubuntu 18.04.3）

答案1

尝试删除所有 nvidia 包（这也会删除 /etc 目录中的文件）：

sudo apt-get --purge remove '*nvidia*'

然后照常重新安装驱动程序：

sudo apt install nvidia-driver-435

看看该文件是否在那里。

答案2

我遇到了同样的问题。当我输入以下命令时，它会告诉我建议安装的驱动程序版本是什么：

mona@goku:~$ sudo ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001F95sv000017AAsd000022C0bc03sc00i00

然后：

sudo apt-get --purge remove '*nvidia*'

和

sudo apt install nvidia-driver-460
