DINO missing detection

[auindoeee]

i trained my own dataset with dino, categories include faces, heads, people, etc. I found that some images miss detection result for whole class when inferencing...
normal：

all 'person' miss detection：


i am so confused....how can i resolve it?

It seems like we meet the same problem. After fine-tuning mm-grounding-dino,when I inference on a 'multi-objects' image,the model can only detects one object.
