Attention：

1）argv[10] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/images_list.txt";该文件表示的是图像对应的标签，格式如下：

cat gray.jpg 1
cat.jpg 1
cat_gray.jpg 1
fish-bike.jpg 2

2）argv[11] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/img_convert/";该路径下为生成的文件，若之前已经生成过，再次执行代码时要确保没有重复文件，否则会报错。

2.执行代码，得到结果

生成的文件如下：
