NullPointer error when training from previous model?

[heraclex12]

Hi,

I am training from my previous model. But I think some problems in this amazing project.
It is AdaptiveGradientDescent and AdaptiveGradientDescentMiniBatch class, it's not allocated so the program get NullPointer error.
I don't know whether the above classes will be allocated empty or use from exist model.

Thank you for your help!
