Hi, if I understand correctly `contrastive_bias` should always be 1? What's the justification for `contrastive_bias=0.5` and `contrastive_bias=0.75`? Thanks!

Hi, I found that the loss used in this repo is a cross-entropy loss between prediction and mask.
`loss = F.binary_cross_entropy_with_logits(pred, mask)`
But the loss mentioned in the paper is a …

There seems to be a problem with the contrastive loss when using 1 GPU to train, training only works when setting no_insgen=true.
The output is:
