tensorflow - 如何在 Arch linux 中降级到 cuda 10.0？

Question

我想在 Arch linux 中将我的 cuda 10.1 降级为 cuda 10.0，因为 tensorflow 只需要 cuda 10.0。

我在 Arch Linux 的 CUDA 10.1 上安装了 tensorflow，但我不知道 tensorflow-gpu 需要 CUDA 10.0 或更低版本。

我尝试将所需的 10.0 库与新的 10.1 库进行符号链接(symbolic link)，但没有成功。

每当我尝试在 python 控制台中导入 tensorflow 时，都会显示找不到“libcublas.so.10.0”。

所以我发现我只能在 CUDA 10.0 上运行 tensorflow，所以现在我想降级我的 CUDA。但我不知道如何在 Arch Linux 中做到这一点。

每次我跑import tensorflow它给出了这个错误。

Failed to load the native TensorFlow runtime.

pacman -S cuda=="10.0"不管用。

我到处搜索，但找不到任何让 Arch Linux 降级到 CUDA 10.0 的正确答案

Answer 1

我已经通过使用 yay 解决了这个问题.与 yay您可以安装旧版本的 cuda和 cudnn .根据我的经验，这比从 archive.org 下载要快。 .
安装 yay在拱门上:

pacman -S --needed git base-devel
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si

搜索您需要的版本:

yay -Ss cuda
yay -Ss cudnn

在写这个答案的那一刻，我需要从 cuda 降级。 11.2 到 11.0。所以我安装了特定版本:

pacman -R cuda cudnn
yay -S cuda-11.0 cudnn8-cuda11.0

对我来说，Tensorflow 在降级后运行顺利。
