@JC-FOSU It is caused by the cocoapi. Probably because there aren't any small objects in your val data or the model does not predict any small objects (I'm not sure). But based on your mAP 0.899, don't worry, try your model!
I guess it's because there are no targets smaller than 32*32 in the val set.
I also have the same problem. It is useless to adjust LR and so on
