How can i train my custom dataset with no object class?

[kimwin2]

I really appreciate your work. Nowadays I try to train TS-CAM with my own dataset. First, I make my own dataset into the CUB dataset format. And I set the no object image to the bounding box value (0,0,0,0). But I failed to train the model. Can you recommend any way to train the model with no object dataset?
