The anchor setting for VOC is mismatched with the paper.

Hi, thanks for your awesome work!

In your paper, you mentioned that you use RPN Anchor Sizes: [8, 16, 32] for VOC.

I noticed that you configure it here:

ssl_detection/detection/train_stg1.py

Line 84 in 5118c64

'TRAIN.LR_SCHEDULE=[7500,40000]', 'RPN.ANCHOR_SIZES=(8,16,32)',

However, according to this file:

ssl_detection/detection/modeling/generalized_stac_rcnn.py

Line 412 in 00d5227

sizes=cfg.RPN.ANCHOR_SIZES,

The RPN.ANCHOR_SIZES only works when you use ResNetC4Model . I think you never use it in all your experiments. ResNetFPNModel is your model. You need to set FPN.ANCHOR_SIZES for ResNetFPNModel.

Correct me if I'm wrong.
