配置YOLO2（ubuntu16.04+cuda8.0+opencv3.1.0）

要求已经安装好了CUDA 8.0 以及OpenCV3.1.0

YOLO官方网站

配置darknet

git clone https://github.com/pjreddie/darknet  
cd darknet  
make  

如果没有报错输入

./darknet  

得到输出

./darknet <function>  

说明darknet配置成功

打开Makefile文件，将开头几行改为

GPU=1
CUDNN=1
OPENCV=1

接着查询自己GPU的计算能力，查看Makefile是否包含，如下我的GPU计算能力为6.1,调整后为：

ARCH= -gencode arch=compute_30,code=sm_30 
      -gencode arch=compute_35,code=sm_35 
      -gencode arch=compute_50,code=[sm_50,compute_50] 
      -gencode arch=compute_61,code=[sm_61,compute_61] 
      -gencode arch=compute_52,code=[sm_52,compute_52]

之后重新编译，就可以实现基于cuda和opencv的编译

下载预训练文件

wget https://pjreddie.com/media/files/yolo.weights  

测试

./darknet detect cfg/yolo.cfg yolo.weights data/dog.jpg  

我得到的结果是：
