Hello Jinfagang, There could be many reasons for this. The loc loss is pretty large, so I guess the problem is with the bounding box regression. It might be helpful to check some places:
- In layers/modules/multibox_loss.py, check that the size of pos after pos = conf_t > 0 is reasonable. It is the number of positive instances and shouldn't be zero or too large.
- If the input image size is not 512 or 300, then you may need to modify the config file
- In preproc (data/data_augment.py ), There is a normalization process for the boxes, make sure that you get the right shapes here. They shouldn't be too small (<0.01)

@PingoLH Thanks so much for advise. I will have an investigate .
