[Kdn-users] How to use your trained_delay_models in ignnition?

Dear professors:       I just read the code you posted on GitHub, and I want to use the ignnition to train a RouteNet-GNN model. I see that you have already a trained_delay model, which is in .ckpt format. However, when I wanted to use your trained model, I found that the ignnition must use a ".hdf5" models. How can I transform a ".ckpt" to a ".hdf5"? Can you help me?      Looking forward to your reply! Thanks!      A student who wants to build a RouteNet GNN model.
