我看了很多页面，要么无法理解他们所说的内容，因为他们不清楚and/or我的知识还不够。
我正在尝试 运行:

这样我就可以使用 GPU 加速 运行 DenseCap 处理一些图像。当我 运行 它时，我得到这个错误：

出于某种原因，当我 运行 $ nvcc -V 时，我得到：
The program 'nvcc' is currently not installed. You can install it by typing:
sudo apt install nvidia-cuda-toolkit
..这是我面临的另一个大问题。当我安装 nvcc 时，它会安装 Cuda 7.5 的工具包，但我有 Cuda 9.0。我使用来自 Cuda's website 的 .deb 文件安装了它。

尝试将您尝试安装的 stnbhwd CMakeLists.txt 中的代码架构（例如 sm_20）更改为更高版本。

如你所说：

Cuda 9.0 不支持 SM_20 架构 (more info)。
