>>>>>>>>> The problem is it shown me It only read 2 images from txt file and it is impossible :

Answer:

　今天出现了 找不到 图像路径下的 .png文件， 查看了 train_data.txt文档，才发现，出错了一个图像：

.png  0 0 0 0 0 0 0 ~~

在io.cpp 第80 和 81 行：

  LOG(INFO) << "FILENAME: " << filename ;
  LOG(INFO) << "cv_read_flag: " << cv_read_flag ;

就会显示出错的地方，然后找到，删除那一张图像即可。
