2016-04-16 11:57:22 -0600	asked a question	Opencv sample train_hog.cpp not working Hi, just started with opencv and I was trying out the train_hog sample but it's not working. I used this example. Compiled while following this tutorial. For the training i'm using the INRIA dataset. This is the error I'm getting ./train --pd=/home/user/Documents/train/INRIA_dataset/ -p=pos.lst --nd=/home/user/Documents/train/INRIA_dataset/ -n=neg.lst Start training......[done] OpenCV Error: Parsing error (SVM model data is invalid, check sv_count, var_* and class_count tags) in write, file /home/user/OpenCV/opencv-3.1.0/modules/ml/src/svm.cpp, line 2038 terminate called after throwing an instance of 'cv::Exception' what(): /home/user/OpenCV/opencv-3.1.0/modules/ml/src/svm.cpp:2038: error: (-212) SVM model data is invalid, check sv_count, var_* and class_count tags in function write Aborted (core dumped) I'm using ubuntu 15.10 64 bit
