The model was trained with a custom dataset and found that nothing was learned

[Viktor-Paul]

hello,recently, I use custom dataset to train a model but found that nothing was learned.because prediction has no result. I am trying to modify the airplane rbox_pascal_airplane. py files, to train the new dataset, and the corresponding DRBox/examples/rbox/deploy/airplane/deploy. py and deploy. prototxt file used for prediction and display.The training process well，I'm not quite sure what caused this problem. Could you give me some advice? Thank you very much.
