【问题描述】：

所以我在网上搜索了这个，这是一个很常见的错误，但我尝试了给定的解决方案无济于事。我的 cmd 日志是：

C:\Users\kosyn_000\Dropbox\OpenCVtrainingdata>opencv_traincascade -data my_trained -vec positives.vec -bg negativedata.txt -numPos 30 -numNeg 76 -numStages 15 -minHitRate 0.995 -w 197 -h 197 -featureType LBP -precalcValBufSize 1024 -precalcIdxBufSize 1024

而我的negativedata.txt 文件有76 行信息，格式如下：

请有人帮我查明问题，因为我仍然不确定为什么会收到此错误。我在 Windows 系统上执行此操作。谢谢。

发现了问题，显然 bg 文件不应该包含约束，所以现在我的文件格式为

它很好地输出了我的 xml 文件；虽然需要一点时间。大声笑，我不敢相信这是一件如此简单的事情让我退缩。
