Evaluation

The results will vary a bit since we do a batched-inference, which yields padded image batch that would be inconsistently embedded while performing linear image patch projection.

Evaluate VQAv2

python run.py with data_root=<ARROW_ROOT> num_gpus=<NUM_GPUS> num_nodes=<NUM_NODES> per_gpu_batchsize=<BS_FITS_YOUR_GPU> task_finetune_vqa_randaug test_only=True load_path="<YOUR_WEIGHT_ROOT>/vilt_vqa.ckpt"

ex)
python run.py with data_root=/data2/dsets/dataset num_gpus=8 num_nodes=1 per_gpu_batchsize=64 task_finetune_vqa_randaug test_only=True load_path="weights/vilt_vqa.ckpt"

output > This script will generate `result/vqa_submit_vilt_vqa.json`, you can upload it to eval.ai (https://eval.ai/web/challenges/challenge-page/830/overview) evaluation server to get test-dev score.
[{"test-dev": {"yes/no": 87.44, "number": 50.2, "other": 62.38, "overall": 71.32}}]

Evaluate NLVR2

python run.py with data_root=<ARROW_ROOT> num_gpus=<NUM_GPUS> num_nodes=<NUM_NODES> per_gpu_batchsize=<BS_FITS_YOUR_GPU> task_finetune_nlvr2_randaug test_only=True load_path="<YOUR_WEIGHT_ROOT>/vilt_nlvr2.ckpt"

Evaluate COCO IR/TR

or you can evaluate zero-shot performance just simply using "<YOUR_WEIGHT_ROOT>/vilt_200k_mlm_itm.ckpt" instead.
