some questions about training

[mrwangxinqwe]

When I want to train, the default value given by val_split is nyu_test. I don't understand what the h5 file given in this file is.The following is the complete error message:
loading model from folder model_weights/final_our
Loading encoder weights...
Loading depth weights...
Loading pose_encoder weights...
Loading pose weights...
Training is using:
cuda
Models and tensorboard events files are saved to:
logs/
Training is using frames:
[0, -2, -1, 1, 2]
