Hello,

I have a problem with save() and load() methods in ml module. for example if I run code:

CvSVM *SVM = new CvSVM;
SVM->predict(DataRow);

I'll obtain this error:

OpenCV Error: Bad argument (The SVM should be trained first) in CvSVM::predict, file /home/wampir/OpenCV-2.4.3/modules/ml/src/svm.cpp, line 2072 terminate called after throwing an instance of 'cv::Exception' what(): /home/wampir/OpenCV-2.4.3/modules/ml/src/svm.cpp:2072: error: (-5) The SVM should be trained first in function CvSVM::predict

Model in "SVM.xml" is saved with: SVM->save("SVN.xml","NET"); of course SVM was previously trained;

When I'm doing the same with CvRTrees, method load() gives me a segmentation fault (core dumped). For CvERTrees, CvGBTrees and CvNormalBayesClassifier it works exactly like for CvSVM.

CvKNearest is bigger problem because i can't even save my trained model to file, for example when I run this code:

KNearest->save("KNearest.xml","NET");

for trained CvKNearest *KNearest=new KNearest; my "KNearest.xml" will contain only:

< ?xml version="1.0"?>
< opencv_storage>

and nothing more. Spaces after < sign are added only for visibility of the code in here. After that Ill obtain this error:

OpenCV Error: The function/feature is not implemented () in CvStatModel::write, file /home/wampir/OpenCV-2.4.3/modules/ml/src/inner_functions.cpp, line 114 terminate called after throwing an instance of 'cv::Exception' what(): /home/wampir/OpenCV-2.4.3/modules/ml/src/inner_functions.cpp:114: error: (-213) in function CvStatModel::write

Can somebody help me, and tell me how to properly save and load my models or if it is a bug fix it?

Thank you very much ;)
