Weird ranges of bbox during evaluation.

[freshn]

The command I run is:

export GPU=1 && CONFIG="fcos_standard_r50_caffe_fpns4_gn-head_1x_TinyPerson640" && CUDA_VISIBLE_DEVICES=6 tools/dist_train.sh configs2/TinyPerson/base/${CONFIG}.py $GPU

During the evaluation every four epochs, part of the messages are shown like:

2021-08-05 12:27:13,251 - mmdet - INFO - Evaluating bbox...

I am wondering are the ranges listed in 'areaRng' correctly? It seems the ranges do not align with the labels in 'areaRngLbl'. From my understanding, the ranges should be [[1,inf],[2,20],[2,8],[8,12],[12,20],[20,32],[32,inf]]. Is there anything I misunderstand?

Hi, your output has no problem. The ouput is area range of object, and waht your understand is size range. while area=size*size.

'areaRng': [[1, 10000000000.0], [1, 400], [1, 64], [64, 144], [144, 400], [400, 1024], [1024, 10000000000.0]],

'sizeRng': [[1,inf],[2,20],[2,8],[8,12],[12,20],[20,32],[32,inf]].

Beside there has no 1x1 object, so [2, 8] is same as [1, 8].

I got it. Thank you.
