   @nikudyshko, @ddavydenko  I spent some time experimenting with this issue. This is an interesting issue.  If I use 2 or 3 characters in following lines to name the variable (e.g ws or wst, bs or bst) then the training fails.
   weights[i] = Symbol::Variable("ws" + std::to_string(i));
   biases[i] = Symbol::Variable("bs" + std::to_string(i));
   
   However, if I use 1 or more than 3 characters then the training proceeds correctly.
   I looked at implementations c++ package API implementations briefly and nothing stood out.  I would have to dive deeper.  Would also need to see if it is reproducible in python.
   
   Will provide an update.
