I just upgraded to 3.2.0 from 2.4.9 and it seems like the save function is broken? All I did was change CvSVM to SVM

SVM svmClassifier = SVM.create(); 
File svm_file = new File(dir, "svm_test.xml");
svmClassifier.save(svm_file.toString());

will now report A/libc: Fatal signal 11 (SIGSEGV) at 0x644e98f8 (code=2), thread 2380 (Thread-6433). The same flow worked fine with 2.4.9 and CvSVM. Help?

the way like you create the SVM is wrong. since opencv 3.0 changed.

You can see this: http://docs.opencv.org/3.1.0/d1/d73/t... for see one example.

Ptr<SVM> svm = SVM::create();

also i find this explanation, the best that i found. https://www.simplicity.be/article/rec...

good luck!

nice, that you're trying to help, but the question i about java, while your answer is about c++.

thanks, @alexander33, but as @berak pointed out, this error seems to be specific to java.

Have you found solution to this save problem?
