OpenCV创建样本失败

我有567张正片图像，在我的

positives.txt

文件中使用以下格式引用（假设每张图像只有一个对象）：

当我跑的时候

opencv_createsamples -info ../data/positives.txt -num 567 -w 256 -h 256 -vec training.vec

我收到以下错误

Unable to open image: ../data//Users/jkarimi91/Documents/Projects/kaggle/right_whale_recognition/data/imgs/train/whale_00195/w_2753.jpg
OpenCV Error: Unknown error code -9 () in cvSetImageROI, file /Users/jhelmus/anaconda/conda-bld/work/opencv-2.4.8/modules/core/src/array.cpp, line 3000

Abort trap: 6

这是什么原因造成的？

结果是我没有正确格式化txt文件；其格式应如下所示（假设每个图像仅包含一个对象）：

path num\u对象x y宽度高度
