Dear @lululxvi ,

Recently I have been watching the course which u have given lessons in Tianyuan Mathematical Centre, and I just installed the deepxde, and run the project fnn_pde in the https://github.com/lululxvi/tutorials/tree/master/20211208_deep_learning_handson
but i only got two figures and the third figure u have mentioned in the video is missing. I don't know how to fix it. Could you provide some help for me, since I'm completely new to it.
Hope for your apply.
