SVM.load() module in python opencv3

Hi! Recently I've tried to rewrite my code from opecv2 to opecv3 and realized, that in opencv3 the SVM.load() module has gone. In my case I setup svn by: > svm = cv2.ml.SVM_create() then I set params, train my svm and save trained svm to file by: > svm.save('file.dat') So the question is, how to load trained SVM from file, which was saved before as above? I can't find any info, also in python docs there's no any method for loading it... Thank for any response ;)
