找不到EmguCV - nvcuda.dll [英] EmguCV - nvcuda.dll could not be found

问题描述

我被要求建立一个实时的人脸识别应用程序，经过一些环顾，我决定尝试EmguCV和OpenCV作为面部识别库。

我目前遇到的问题是尝试获取SDK安装和工作。我已按照此处找到的说明尝试运行，但我仍然无法运行样品。每当我尝试运行它们时，会出现错误

 程序无法启动，因为计算机中缺少nvcuda.dll 。 
尝试重新安装程序以解决此问题。 
 

我已经尝试了大多数常见的修复，例如将bin文件夹添加到我的环境路径，

• EmguCV版本2.4.2.1777-windows-x64-gpu


• Windows 8


• AMD Radeon HD 6700系列显卡。

我假设这是一个问题，我没有一个nVidia显卡，但我不知道我可以做什么。现在，我将尝试重新编译源代码，而不是使用下载的.exe，看看是否有帮助。

有任何建议吗？

$ b有相同的问题，EmguCV 2.4.2（无论是x86还是x64）编译GPU，你必须有nvidia GPU CUDA支持。所以，如果你想要eg。从C＃中的2.4版本开始 - 等待非GPU版本或购买/借用CUDA卡;）

I've been asked to build a real-time face recognition application, and after some looking around I've decided to try EmguCV and OpenCV as the facial recognition library.

The issue I'm having at the moment is trying to get the SDK installed and working. I've followed the instructions found here to try and get it running, but I still can't run the samples. Whenever I try and run them, I get the error

The program can't start because nvcuda.dll is missing from your computer. 
Try reinstalling the program to fix this problem.

I've tried most of the usual fixes, such as adding the bin folder to my environment path and copying the dll's into my system32 folder, but none of it seems to work.

• EmguCV version 2.4.2.1777-windows-x64-gpu
• Windows 8
• AMD Radeon HD 6700 series graphics card.

I'm assuming this is an issue with the fact that I dont have an nVidia graphics card, but I'm not sure what I can do about it. For now, I'm going to try recompiling the source rather than using the downloaded .exe, and seeing if that helps.

Any suggestions?

解决方案

Had the same problem, EmguCV 2.4.2 (no matter if x86 or x64) is compiled with GPU and you have to had nvidia GPU with CUDA support. So, if you want for eg. Fisherfaces from 2.4 in C# - wait for non-GPU release or buy/borrow CUDA card ;)
