Description

Hi, I'm having backward compatibility problems between version 2.4.9 and 3.0.0 beta.

a trained neural network trained on 2.4.9 cant be opened on 3.0.0 beta via

m_classifier = StatModel::load<ANN_MLP>("constraints.yml");

throws the error:

OpenCV Error: Bad argument (The file node should be a numerical scalar or a sequence) in cvStartReadRawData, file ..\..\..\modules\core\src\persistence.cpp, line 3198
