object detected but dimension seem not good

[thanhpt93]

Hi author, I have issue after I train and test my model, object was detected but dimension seem not good, maybe my anchor size is fail? Can you help me edit some config to get good result?
Bellow is result image, you can see the object car was detected but see z and x coordinate not good

For more detail: I train with custom dataset use pretrained model: pv_rcnn_8369.pth, base pv_rcnn.yaml config and have 3 class
Thank you very much!
