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?
