About "train_ggcnn.py"

[linjuechu]

I extracted some of the information from the Cornell dataset to form a miniorell dataset，I think I've successfully converted the PCD files to depth images, but when I want to training，run"train_ggcnn.py",it can generate the appropriate files “output/models/" ,The files in ”models“ folder are empty folders，I don't know what went wrong, what should be done to be right.
If you know, hopefully you can tell me,thank you!
