Environments

• Ubuntu 16.04
• CUDA 10.1
• Python 3.8
• PyTorch 1.5.1

We used Anaconda to setup a deep learning workspace that supports PyTorch. Run the following script to install the required packages.

conda create --name ws_dual_py3 python=3.8
conda activate ws_dual_py3
git clone https://github.com/danieljf24/hybrid_space.git
cd hybrid_space
pip install -r requirements.txt
conda deactivate

Dual Encoding on MSRVTT10K

Required Data

Run the following script to download and extract MSR-VTT (msrvtt10k-resnext101_resnet152.tar.gz(4.3G)) dataset and a pre-trained word2vec (vec500flickr30m.tar.gz(3.0G). The data can also be downloaded from Baidu pan (url, password:p3p0) or Google drive (url). For more information about the dataset, please refer to here. The extracted data is placed in $HOME/VisualSearch/.

ROOTPATH=$HOME/VisualSearch
mkdir -p $ROOTPATH && cd $ROOTPATH

# download and extract dataset
wget http://8.210.46.84:8787/tpami2021/msrvtt10k-resnext101_resnet152.tar.gz
tar zxf msrvtt10k-resnext101_resnet152.tar.gz -C $ROOTPATH

# download and extract pre-trained word2vec
wget http://lixirong.net/data/w2vv-tmm2018/word2vec.tar.gz
tar zxf word2vec.tar.gz -C $ROOTPATH

Model Training and Evaluation

Run the following script to train and evaluate Dual Encoding network with hybrid space on the official partition of MSR-VTT. The video features are the concatenation of ResNeXt-101 and ResNet-152 features. The code of video feature extraction we used in the paper is available at here.

conda activate ws_dual_py3
./do_all.sh msrvtt10k hybrid resnext101-resnet152

Running the script will do the following things:

1. Train Dual Encoding network with hybrid space and select a checkpoint that performs best on the validation set as the final model. Notice that we only save the best-performing checkpoint on the validation set to save disk space.
2. Evaluate the final model on the test set. Note that the dataset has already included vocabulary and concept annotations. If you would like to generate vocabulary and concepts by yourself, run the script ./do_vocab_concept.sh msrvtt10k 1 $ROOTPATH.

If you would like to train Dual Encoding network with the latent space learning (Conference Version), please run the following scrip:

./do_all.sh msrvtt10k latent resnext101-resnet152 $ROOTPATH

To train the model on the Test1k-Miech partition and Test1k-Yu partition of MSR-VTT, please run the following scrip:

./do_all.sh msrvtt10kmiech hybrid resnext101-resnet152 $ROOTPATH
./do_all.sh msrvtt10kyu hybrid resnext101-resnet152 $ROOTPATH

Evaluation using Provided Checkpoints

The overview of pre-trained checkpoints on MSR-VTT is as follows.

Note that if you would like to evaluate using our trained checkpoints, please make sure to use the vocabulary and concept annotations that are provided in the msrvtt10k-resnext101_resnet152.tar.gz.

How to run Dual Encoding on other datasets?

Our code supports dataset structure:

• Single-folder structure: train, validation and test subset are stored in a folder.
• Multiple-folder structure: train, validation and test subset are stored in three folders respectively.

Single-folder structure

Store the train, validation and test subset into a folder in the following structure.

${collection}
├── FeatureData
│   └── ${feature_name}
│       ├── feature.bin
│       ├── shape.txt
│       └── id.txt
└── TextData
    └── ${collection}train.caption.txt
    └── ${collection}val.caption.txt
    └── ${collection}test.caption.txt

• FeatureData: video frame features. Using txt2bin.py to convert video frame feature in the required binary format.
• ${collection}train.caption.txt: training caption data.
• ${collection}val.caption.txt: validation caption data.
• ${collection}test.caption.txt: test caption data. The file structure is as follows, in which the video and sent in the same line are relevant.

video_id_1#1 sentence_1
video_id_1#2 sentence_2
...
video_id_n#1 sentence_k
...

Please run the script to generate vocabulary and concepts:

./util/do_vocab_concept.sh $collection 0 $ROOTPATH

Run the following script to train and evaluate Dual Encoding on your own dataset:

./do_all_singlefolder.sh ${collection} hybrid ${feature_name} ${rootpath}

Multiple-folder structure

Store the training, validation and test subsets into three folders in the following structure respectively.

${subset_name}
├── FeatureData
│   └── ${feature_name}
│       ├── feature.bin
│       ├── shape.txt
│       └── id.txt
└── TextData
    └── ${subset_name}.caption.txt

• FeatureData: video frame features.
• ${dsubset_name}.caption.txt: caption data of corresponding subset.

You can run the following script to check whether the data is ready:

./do_format_check.sh ${train_set} ${val_set} ${test_set} ${rootpath} ${feature_name}

where train_set, val_set and test_set indicate the name of training, validation and test set, respectively, ${rootpath} denotes the path where datasets are saved and feature_name is the video frame feature name.

Please run the script to generate vocabulary and concepts:

./util/do_vocab_concept.sh ${train_set} 0 $ROOTPATH

If you pass the format check, use the following script to train and evaluate Dual Encoding on your own dataset:

./do_all_multifolder.sh ${train_set} ${val_set} ${test_set} hybrid ${feature_name} ${rootpath}
