Download Pretrained Weights

We provide five pretrained weights

1. ViLT-B/32 Pretrained with MLM+ITM for 200k steps on GCC+SBU+COCO+VG (ViLT-B/32 200k) link
2. ViLT-B/32 200k finetuned on VQAv2 link
3. ViLT-B/32 200k finetuned on NLVR2 link
4. ViLT-B/32 200k finetuned on COCO IR/TR link
5. ViLT-B/32 200k finetuned on F30K IR/TR link

Out-of-the-box MLM + Visualization Demo

pip install gradio==1.6.4
python demo.py with num_gpus=<0 if you have no gpus else 1> load_path="<YOUR_WEIGHT_ROOT>/vilt_200k_mlm_itm.ckpt"

ex)
python demo.py with num_gpus=0 load_path="weights/vilt_200k_mlm_itm.ckpt"

Out-of-the-box VQA Demo

pip install gradio==1.6.4
python demo_vqa.py with num_gpus=<0 if you have no gpus else 1> load_path="<YOUR_WEIGHT_ROOT>/vilt_vqa.ckpt" test_only=True

ex)
python demo_vqa.py with num_gpus=0 load_path="weights/vilt_vqa.ckpt" test_only=True
