Reproduce OV2Seg results on LVVIS val and test set

[sumcher-ng]

Thank you for your great work.

I used your scripts/train.sh to train ov2seg with Resnet50 backbone on 4 gpus and batch size 8 with total 370k iterations (all other hparams are kept unchanged), but cannot obtain the reported numbers in table 2 in the paper.

• reported numbers: 14.1 AP, 18.1 AP_b, 9.4 AP_n
• provided R50 weight: 14.2 AP, 17.1 AP_b, 12.0 AP_n
• my output: 12.52 AP, 15.5 AP_b, 10.33 AP_n I used scripts/eval_video.sh for inference.

Do I need to config anything else? or can you please share the training log of the provided R50 version? Thank you!

Sorry that there is a mistake in the paper. We checked the log and the batch size was 16 indeed. Please try it with bs=16. We will fix the typo in the paper.
