使用 OpenCv 2.4.10 + Cuda 7.5 + W10 不支持 GPU [英] No GPU Support using OpenCv 2.4.10 + Cuda 7.5 + W10

问题描述

我正在尝试使用以下方法启动和运行 GPU:

• OpenCv 2.4.10
• Visual Studio 2013
• Cuda 工具包 7.5(已测试并运行的 cuda 示例)
• Windows 10 x64
• 采用 NVIDIA GEFORCE GTX 860M 的联想 Y50

我使用 CMake 编译 OpenCv，WITH_CUDA=ON，然后通过打开 OpenCv.sln 安装库并构建 ALLBUILD 和 INSTALL 项目.

将我的项目配置设置为:

• VC++ 目录

• VC++ Directories

• 包括目录:
  • C:\Program Files\NVIDIA GPU 计算工具包\CUDA\v7.5\include
  • C:\OpenCv\opencv\build\install\include(包含编译的库)
  • C:\OpenCv\opencv\build\include

  Linker-general-附加库

  Linker-general-Additional libraries

  • C:\OpenCv\opencv\build\x64\vc12\lib
  • C:\OpenCv\opencv\build\install\x64\vc12\lib

  链接器输入附加依赖

  • opencv_calib3d2410d.lib
  • opencv_contrib2410d.lib
  • opencv_core2410d.lib
  • opencv_features2d2410d.lib
  • opencv_flann2410d.lib
  • opencv_gpu2410d.lib
  • opencv_highgui2410d.lib
  • opencv_imgproc2410d.lib
  • opencv_legacy2410d.lib
  • opencv_ml2410d.lib
  • opencv_nonfree2410d.lib
  • opencv_objdetect2410d.lib
  • opencv_ocl2410d.lib
  • opencv_photo2410d.lib
  • opencv_stitching2410d.lib
  • opencv_superres2410d.lib
  • opencv_ts2410d.lib
  • opencv_video2410d.lib
  • opencv_videostab2410d.lib

  我的环境变量:路径= C:\Program Files\NVIDIA GPU Computing;Toolkit\CUDA\v7.5;C:\OpenCv\opencv\build\install\x64\vc12\bin;C:\OpenCv\opencv\build\x64\vc12\垃圾箱

  My environment variables: Path= C:\Program Files\NVIDIA GPU Computing;Toolkit\CUDA\v7.5;C:\OpenCv\opencv\build\install\x64\vc12\bin;C:\OpenCv\opencv\build\x64\vc12\bin

  测试代码:

     #include "opencv2\opencv.hpp"
     #include "opencv2\gpu\gpu.hpp"
  
      using namespace cv::gpu;
      using namespace std;
  
      int main() {
          {
          setDevice(0); 
          int gpu = getCudaEnabledDeviceCount();
          cout << gpu ;
          system("pause");
          return 0;
          }
  
  }in
  

  但是 setDevice 抛出

  But setDevice throws

  没有 GPU 支持(该库编译时没有 CUDA 支持)EmptyDeviceInfoFuncTable::setDevice, 文件c:\builds\2_4_PackSlave-win64-vc12-shared\opencv\dynamicuda\include\opencv2/dynamiccuda/dynamicuda.hpp.第 84 行

  no GPU support (The library is compiled without CUDA support) in EmptyDeviceInfoFuncTable::setDevice, file c:\builds\2_4_PackSlave-win64-vc12-shared\opencv\dynamicuda\include\opencv2/dynamiccuda/dynamicuda.hpp. line 84

  如果我评论 setDevice(0) 仍然没有检测到 gpu，getCudaEnabledDeviceCount 返回 0.

  and if i comment setDevice(0) the gpu is still not detected, getCudaEnabledDeviceCount returns 0.

  推荐答案

  问题是 Opencv 2.4.10 支持 CUDA 4.2 而我的显卡只兼容 CUDA 6.5 和 7.5 ，我通过安装 OpenCV 3.0.0 解决了

  The problem is that Opencv 2.4.10 supports CUDA 4.2 and my video card is compatible only with CUDA 6.5 and 7.5 , I solved by installing OpenCV 3.0.0
