Low mAP on coco with mask_rcnn_x101_32x8d_fpn_mstrain-poly_3x

[jonas-doevenspeck]

Describe the bug When running tools/test.py on mask_rcnn_x101_32x8d_fpn_mstrain-poly_3x on coco, the performance (mAP) is much lower than reported here: https://github.com/open-mmlab/mmdetection/tree/master/configs/mask_rcnn .
For other models, I was able to reproduce the reported results. Is it possible there is something wrong with the config or checkpoint of this network?

-tools/test.py output: bbox: 40.4%, segm: 35.9% -mmdetection github page: bbox: 44.3%, segm: 39.5%

Reproduction

1. What command or script did you run?

python tools/test.py configs/mask_rcnn/mask_rcnn_x101_32x8d_fpn_mstrain-poly_3x_coco.py checkpoints/mask_rcnn/mask_rcnn_x101_32x8d_fpn_mstrain-poly_3x_coco/mask_rcnn_x101_32x8d_fpn_mstrain-poly_3x_coco_20210607_161042-8bd2c639.pth --eval bbox segm

2. Did you make any modifications on the code or config? Did you understand what you have modified? No modifications
3. What dataset did you use? Coco2017 validation set

2. You may add addition that may be helpful for locating the problem, such as
   • How you installed PyTorch [e.g., pip, conda, source] With pip

Could anyone have a look at this? @hhaAndroid @BIGWangYuDong

[hhaAndroid]

@jonas-doevenspeck Thanks a lot for your feedback, I'll check it out.

[BIGWangYuDong]

seems the ckpt have some problem, we will fix it ASAP

[jonas-doevenspeck]

@BIGWangYuDong and @hhaAndroid any update on this by any chance? If it's not fixed, could the table here (https://github.com/open-mmlab/mmdetection/tree/master/configs/mask_rcnn) be updated with the lower number that is now produced? It is confusing/misleading to have different numbers in the table and what is achieved by the uploaded checkpoint.
