about validation

[ArtemisZGL]

First thanks to you great work ! But I have some questions about it, why in the training code doesn't have validation part ? Can I just add it like the testing code do ? but in the testing code the input batch size is 1, and I don't know can I inference one batch. And when I use the cmu clb dataset to train the model, I can see the alignment is well for the training data, but when I use the ckpt to inference, it's quiet bad. Is that the model is overfitting for the small dataset (about one hour) ?
