This repository contains the code for the following paper:

• Daqing Liu, Hanwang Zhang, Feng Wu, Zheng-Jun Zha, Learning to Assemble Neural Module Tree Networks for Visual Grounding. in ICCV, 2019. (PDF)

1. Install Python 3 (Anaconda recommended)
2. Install Pytorch v1.0 or higher:

pip3 install torch torchvision

3. Clone with Git, and then enter the root directory:

git clone --recursive https://github.com/daqingliu/NMTree.git && cd NMTree

4. Prepare data
   • Follow data/README.md to prepare images and refcoco/refcoco+/refcocog annotations. Or simply run:

   # it will cost some time accordding to your network
   bash data/prepare_data.sh

   • Our visual features are extracted by MAttNet, please follow the instruction. Or just download and uncompress Refcocog visual features into data/feats/refcocog_umd for testing this repo.
   • Preprocess vocabulary:

   python misc/parser.py --dataset refcocog --split_by umd

python tools/train.py \
    --id det_nmtree_01 \
    --dataset refcocog \
    --split_by umd \
    --grounding_model NMTree \
    --data_file data_dep \
    --batch_size 128 \
    --glove glove.840B.300d_dep \
    --visual_feat_file matt_res_gt_feats.pth

python tools/eval_gt.py \
    --log_path log/refcocog_umd_nmtree_01 \
    --dataset refcocog \
    --split_by umd \

python tools/eval_det.py \
    --log_path log/refcocog_umd_nmtree_01 \
    --dataset refcocog \
    --split_by umd
