我正在尝试安装一个开源软件“openpose”，我需要为其安装 cuda、cudnn 和 nvidia 驱动程序。nvidia-smi 的输出是：

+-----------------------------------------------------------------------------+

+-----------------------------------------------------------------------------+

并cat /usr/include/cudnn.h | grep CUDNN_MAJOR -A 2给出的输出：

#define CUDNN_MAJOR 7
#define CUDNN_MINOR 6
#define CUDNN_PATCHLEVEL 5

在成功安装上述所有软件和库后，我终于运行了 openpose：

./build/examples/openpose/openpose.bin --video examples/media/video.avi

但输出是：

我经历了很多在线讨论，但无法弄清楚如何解决这个问题。

我对 CUDNN 也有同样的问题。

虽然不理想，但我一直在没有 CUDNN 的情况下运行。在 cmake-gui 中取消选中 USE_CUDNN 然后编译。运行 openpose 时，我还必须减少 -net_resolution。

例如：./build/examples/openpose/openpose.bin -net_resolution 256x192 分辨率越高，FPS 越慢。
