> Reduce memory footprint by Python generator for parameter gradient

> The parameter gradient tensors are stored in memory until BP is finished.
> This is not necessary as we can update the parameter once its gradient is
> ready. Then we free the gradient tensor.
> In this way, we reduce the memory footprint by avoiding store all gradient
> tensors.
