• Paper

Installation

1. Environmental Setup

$ conda create -n SQA python=3.7
$ conda install -c pytorch pytorch torchvision # PyTorch 1.7.1, torchvision 0.8.2, CUDA=11.0
$ conda install cython scipy
$ pip install pycocotools
$ pip install opencv-python
$ pip install wandb

You should also download CLIP.

2. HOI dataset setup

Our SQA supports the experiments for both V-COCO and HICO-DET dataset. Download the dataset under the pulled directory. For HICO-DET, we use the annotation files provided by the PPDM authors. Download the list of actions as list_action.txt and place them under the unballed hico-det directory. Below we present how you should place the files.

# V-COCO setup
$ git clone https://github.com/s-gupta/v-coco.git
$ cd v-coco
$ ln -s [:COCO_DIR] coco/images # COCO_DIR contains images of train2014 & val2014
$ python script_pick_annotations.py [:COCO_DIR]/annotations

# HICO-DET setup
$ tar -zxvf hico_20160224_det.tar.gz # move the unballed folder under the pulled repository

If you wish to download the datasets on our own directory, simply change the 'data_path' argument to the directory you have downloaded the datasets.
```bash
--data_path [:your_own_directory]/[v-coco/hico_20160224_det]

3. Training/Testing on V-COCO

python main.py --validate \
    --num_hoi_queries 32 --batch_size 4 --lr 5e-5 --HOIDet --hoi_aux_loss --no_aux_loss \ 
    --dataset_file vcoco  --data_path v-coco --detr_weights https://dl.fbaipublicfiles.com/detr/detr-r50-e632da11.pth \
    --output_dir checkpoints/vcoco --group_name SQA --run_name vcoco_run1

• Add --eval option for evaluation

4. Training/Testing on HICO-DET

Training with pretrained DETR detector on COCO.

python main.py --validate \ 
    --num_hoi_queries 32 --batch_size 4 --lr 5e-5 --HOIDet --hoi_aux_loss --no_aux_loss \
    --dataset_file hico-det --data_path hico_20160224_det --detr_weights https://dl.fbaipublicfiles.com/detr/detr-r50-e632da11.pth \
    --output_dir checkpoints/hico-det --group_name SQA --run_name hicodet_run1

Jointly fine-tune object detector & HOI detector

python main.py --validate \
    --num_hoi_queries 32 --batch_size 2 --lr 1e-5 --HOIDet --hoi_aux_loss \
    --dataset_file hico-det --data_path hico_20160224_det \
    --output_dir checkpoints/hico-det --group_name SQA --run_name hicodet_run1/jointly-tune \
    --resume checkpoints/hico-det/SQA/best.pth --train_detr

Visualization

• If you want to visualize the detection results and the attention heat map, add --resume /directory of checkpoint, such as: checkpoints/hico-det/SQA/best.pth ,--demo and --img_file /directory of images.
