Problem of neural network training with CvANN_MLP

edit

Hi,

I am training some HOG features (729 features per example) with CvANN_MLP. It looks like the size of training set is limited for CvANN_MLP. If I pass 3000 examples to the train() function, it works fine. But if I feed 6000 or more examples, the train() function will return immediately with return code 0.

What is the problem?
