我一直在按照本指南在Ubuntu上设置我的GPU（1080ti）。 https://pratos.github.io/setup-tensorflow-gpu-on-ubuntu.html
顺便说一句，昨天一切正常，但TensorFlow抱怨CUDA，这就是我决定用旧驱动程序重新安装所有内容的原因。
无论如何，我在运行deviceQuery时遇到错误：
$:~/CUDA-8.0-samples/1_Utilities/deviceQuery$ sudo ./deviceQuery
./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 38
-> no CUDA-capable device is detected
Result = FAIL

答案 0 :(得分：1)
问题是cuda8.0 runfile中的驱动程序375.26对于1080ti来说太旧了。您应该在其official website下载1080ti的相应驱动程序。
答案 1 :(得分：0)
解决此问题的方法是实际使用较旧的驱动程序。我不记得哪个版本适用，但是较新的驱动程序不适用于我。
