【问题描述】:
从 18.04 升级到 Ubuntu 20.04 后,Tensorflow 不再能够使用我的 gpu,因为它试图混合和加载不同的版本(一些 10 和一些 11)。这是一台 System76 机器,我从 System76 安装了 cuda 10.1(因此它可以与 System76 nvidia 驱动程序一起使用)。运行tensorflow时出现以下错误:

请注意,所有警告都是针对尝试加载 Cuda 版本 11 的,但它仅针对某些库。版本 10 加载正常。
这是 nvcc --version 的输出

我看到 nvidia-smi 输出中的驱动程序版本是 11 版,但据我了解,这与 cuda 运行时无关。这只是驱动程序支持的版本。如果我错了,请纠正我。
我必须使用版本 10,因为这是 System76 支持的版本,并且在升级之前它运行良好。我也尝试通过 pip3 卸载并重新安装 Tensorflow,但没有成功。
有谁知道如何将所有库同步到 10.1 版?我还尝试手动放置版本 11 的库并让 Tensorflow 使用混合版本(这当然是个坏主意)但它无法识别它们(或者我没有正确放置它们)。

对于当前的 tensorflow 版本,您必须使用 CUDA 11.0。您的困惑归结为误解 CUDA 11.0 的内容并非全部版本为 11.x docs.nvidia.com/cuda/archive/11.0/cuda-toolkit-release-notes/…

@talonmies 谢谢。你是对的。根据您的评论,我能够解决它。
