Updates (April 19th):

• QnA was accepted for Oral Presentation at CVPR 2022
• Implementation of QnA layer and other components are available
• QnA-ViT and training code will be released later this month
  • Code went refactoring - under testing and reproducing results

Evaluation

Download the model parameters and copy

CUDA_VISIBLE_DEVICES=0 python3 main.py --eval_only \
    --workdir <MODEL_DIR> \ 
    --config configs/imagenet_qna.py \
    --config.model_name <MODEL_DIR> \ 
    --config.dataset_version 5.1.0  \
    --config.data_dir <DATA_DIR> \
    --config.batch_size <BATCH_SIZE> \
    --config.half_precision=False

Flags:

- workdir : location to the checkpoints directory
- model_name : the model name, e.g., qna_vit_tiny (see table above for model names - use lowercase names only).
- dataset_version : Tensorflow datasets ImageNet dataset version. Mine was (5.1.0),
                     you can change according to your installed version.
- data_dir : the location of the ImageNet directory (need to have the validation set)
- batch_size : the evaluation batch size
