LAPVQA — VQA (Captioning-Pretrained Encoder)
Part of the LAPVQA collection.
Description
VQA task head trained on top of the LAPVQA captioning-pretrained encoder
(lapvqa-pretrain-captioning).
The encoder is kept frozen; this checkpoint contains the VQAHead state dict only.
The encoder outputs 1024-dim patch tokens (ViT-L/14).
Loading

ckpt = torch.load("pretrain-captioning_best.pt", map_location="cpu")
head = VQAHead(vis_dim=1024)
head.load_state_dict(ckpt)
head.eval()
