.懒惰阿喵: 我在运行的时候中断了，好像是在train函数那里出错，显示OpenCV(3.4.2) Error: Assertion failed (samples.type() == 5 || samples.type() == 4) in cv::ml::TrainDataImpl::setData, file c:\build\3_4_winpack-build-win64-vc15\opencv\modules\ml\src\data.cpp, line 259 OpenCV: terminate handler is called! The last OpenCV error is: OpenCV(3.4.2) Error: Assertion failed (samples.type() == 5 || samples.type() == 4) in cv::ml::TrainDataImpl::setData, file c:\build\3_4_winpack-build-win64-vc15\opencv\modules\ml\src\data.cpp, line 259 D:\opencv课设\课程设计-手写数字识别\x64\Debug\课程设计-手写数字识别.exe (进程 5840)已退出，代码为 3。 这该怎么解决呢5555
