Question about mask accuracy calculation

[jwubz123]

In mask accurate calculation, we only have pred_mask_logits without sigmoid, the value is out of [0,1], (pred_mask_logits > 0.5) selection seems to be meaningless, is there any processing about pred_mask_logits that I overlooked? mask_accurate = (pred_mask_logits > 0.5) == (gt_masks > 0.5)
