我安装了gcc-5和gcc-7,当我尝试使用'make'编译cuda样本时,我遇到了很多错误,经过一些研究后我发现我需要降级我的gcc,所以我认为系统使用gcc-7而不是其他,所以我使用purge卸载它,但是gcc甚至没有被识别,gcc --version给出了错误。所以我也清除了另一个gcc并再次安装了'sudo apt-get update'和'suda apt-get install build essential'。 'gcc --version'现在已经可以使用了,但是我的cuda司机不再工作了。 nvidia-smi导致“命令未找到”,我无法运行任何cuda样本,虽然现在我可以编译它。例如,deviceQuery返回:
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
'nvcc --version'也有效,这是输出:

我没有改变我的驱动程序,但重新安装gcc打破了他们。我该如何解决这个问题?
由于
- 编辑 -
当我'找到nvidia-smi'时,我得到以下结果:
/etc/alternatives/x86_64-linux-gnu_nvidia-smi.1.gz
/usr/bin/nvidia-smi
/usr/share/man/man1/nvidia-smi.1.gz
虽然当我进入那些目录时,比如/ usr / bin没有nvidia-smi可执行文件,在/ usr / share / man / man1 /下没有nvidia-smi.1.gz
做'cat / proc / driver / nvidia / version'我得到:
NVRM version: NVIDIA UNIX x86_64 Kernel Module 384.111 Tue Dec 19 23:51:45 PST 2017
GCC version: gcc version 7.2.0 (Ubuntu 7.2.0-1ubuntu1~16.04)
它仍然显示旧的gcc,我现在有gcc-5,而不是7
答案 0 :(得分:0)
我设法解决了这个问题,实际上非常简单,我只需要重新安装我的nvidia驱动程序:
sudo apt-get purge nvidia*
sudo apt-get update
sudo apt-get install nvidia-384
