Question

我试图在Ubuntu 16.04上安装Opencv 3.2.0和Nvidia CUDA工具包8.0，但我无法将它们配置在一起。当我尝试使用两者创建项目时出现以下错误：

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
    Could NOT find CUDA: Found unsuitable version "8.0", but required is exact
    version "7.5" (found /usr/local/cuda)

-- Configuring incomplete, errors occurred!

我尝试过安装cuda toolkit 7.5，但我认为它与ubuntu 16.04不兼容。我现在真的很无能，我希望有人可以帮忙解决这个问题。感谢

所以我通过管理安装toolkit 7.5解决了这个问题。我是这样做的：

更新了我的操作系统的nvidia驱动程序

下载cuda toolkit 7.5并将其解压缩到一个文件夹

def parse(self, response):
    ...

    yield Request(url='myurl', callback=self.some_other_method)

def some_other_method(self, response):
    ...
    # play with the response object of the request done to `myurl`

按Ctrl + Alt + F1进入虚拟控制台并关闭 lightdm服务

$ mkdir ~/Downloads/NVIDIA_TOOLKIT
$ cd ~/Downloads
$ ./cuda_7.5.18_linux.run -extract=~/Downloads/NVIDIA_TOOLKIT;

cd下载并安装提取的工具包和示例
```
$ sudo service lightdm stop
```

在.bashrc文件中设置环境变量

$ cd ~/Downloads/NVIDIA_TOOLKIT
$ sudo ./cuda-linux64-rel-6.0.37-18176142.run
$ sudo ./cuda-samples-linux-6.0.37-18176142.run

重新启用lightdm服务

$ PATH=/usr/local/cuda-7.5/bin
$ LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64

重新启动，您应该可以使用nvcc编译器
对于openCV，您必须将gcc / g ++编译器降级到4.9，因为它与更高版本不兼容

使用CUDA toolkit 8.0安装openCV
