SVM->trainAuto() Segmentation fault (core dumped) #15984
Description
System information (version)
- OpenCV => 4.1.2-dev
- Operating System / Platform => ArchLinux 5.3.11-arch1-1 x86_64 GNU/Linux (31.0 GiB)
- Compiler => Eclipse/Cmake
Detailed description
The outSVM->train(pt) can run , but the trainAuto(pt) can't work .
Steps to reproduce
Code:
outSVM = cv::ml::SVM::create();
outSVM->setType(SVM::C_SVC);
outSVM->setKernel(SVM::CHI2);
Ptr<TrainData> pt = ml::TrainData::create(samples, ml::ROW_SAMPLE,
labels);
// bool result = outSVM->train(pt);
bool result = outSVM->trainAuto(pt);Debug informetion:
