问题描述

当代码到达以下行时,我在opencv中的人脸识别器中获取访问冲突写入位置:model-> train(images,labels);

I get access violation writing location in face recognizer in opencv when the code getting to this line: model->train(images, labels);

错误:WHomeCamera.exe中0x00007FF9B494321B(opencv_core331.dll)的未处理异常:0xC0000005:访问冲突写入位置0x0000000100000014.发生
