CUDA 无法检测到显卡

我遇到了一个问题，我收到一条错误消息

    Exception during execution: CUDA error: no CUDA-capable device is detected (src/cuda/lm/Cuda.cu:60)

有关显卡的一些信息：

    $ lspci -nnk | grep "VGA\|'Kern'\|3D\|Display" -A2

如果您使用的是 Ubuntu 14.04，则可以直接从 Ubuntu 软件中心安装 nvidia-331、NVIDIA CUDA 工具包和 NVIDIA CUDA 5.5 运行时库。libcudart5.5 是 NVIDIA CUDA 运行时库的软件包名称。libcudart5.5 需要 nvidia-331 或更新的图形驱动程序。默认的 Ubuntu 14.04 存储库中还有一个 NVIDIA CUDA 工具包软件包 (nvidia-cuda-toolkit)，与 libcudart5.5 一样，它也是 5.5 版本。

上面提到的三个软件包在我的 Ubuntu 14.04 上运行，配有 NVIDIA GeForce GT 610 显卡。您也可以安装 nvidia-331-updates 软件包，而不是 nvidia-331。
