Code

Environment Configuration

conda create -y -n dibs python=3.8
conda activate dibs
pip install torch==1.12.0+cu116 torchvision==0.13.0+cu116 torchaudio==0.12.0 --extra-index-url https://download.pytorch.org/whl/cu116
conda install ffmpeg
pip install -r requirement.txt
git clone --recursive https://github.com/haowuxc/DIBS.git
cd DIBS/pdvc/ops
sh make.sh

Training and Evaluation

1. Training with pseudo boundaries on YouCook2 and ActivityNet.

python train.py --cfg_path cfgs/anet_clip_refine.yml
python train.py --cfg_path cfgs/yc2_univl_refine.yml

2. Pretraining using HowTo100M video subset.

python train.py --cfg_path cfgs/howto-anet_anet_clip_refine.yml
python train.py --cfg_path cfgs/howto-yc2_yc2_univl_refine.yml

3. Fine-tuning on YouCook2 and ActivityNet.

python train_ft2_gt.py --cfg_path cfgs/howto-anet_anet_clip_refine.yml
python train_ft2_gt.py --cfg_path cfgs/howto-yc2_yc2_univl_refine.yml

4. Evaluation on YouCook2 and ActivityNet.

YouCook2
python eval.py  --eval_save_dir SAVE_PATH --eval_folder CONFIG_NAME --eval_caption_file data/yc2/captiondata/yc2_val.json --eval_proposal_type queries --gpu_id 0

# ActivityNet
python eval.py  --eval_save_dir SAVE_PATH --eval_folder CONFIG_NAME --eval_caption_file data/anet/captiondata/val_1.json --eval_proposal_type queries --gpu_id 0

Note:

• SAVE_PATH is the folder where all files will be stored.
• CONFIG_NAME is the subfolder path of the specified configuration, i.e. model_path = os.path.join(SAVE_PATH, CONFIG_NAME).
