About convergence rate #12

Thanks for your great work! It can be seen from the log that Adam is very stable, but the convergence time is longer. I tried to torch.optim.lbfgs to speed up the convergence, but I don’t understand why nan always appears in training. Can you provide some solutions? Have been troubled for a long time, looking forward to your reply!
