EMCL-Net

This is the PyTorch code of the EMCL-Net.

Setup code environment

conda create -n EMCL python=3.9
conda activate EMCL
pip install -r requirements.txt
pip install torch==1.8.1+cu102 torchvision==0.9.1+cu102 -f https://download.pytorch.org/whl/torch_stable.html

Download Datasets

MSRVTT

For MSRVTT, the official data and video links can be found in link.

For the convenience, the splits and captions can be found in sharing from CLIP4Clip,

wget https://github.com/ArrowLuo/CLIP4Clip/releases/download/v0.0/msrvtt_data.zip

Besides, the raw videos can be found in sharing from Frozen in Time, i.e.,

wget https://www.robots.ox.ac.uk/~maxbain/frozen-in-time/data/MSRVTT.zip

MSVD

For MSDC, the official data and video links can be found in link.

For convenience, we share the processed dataset in link.

Compress Video

python preprocess/compress_video.py --input_root [raw_video_path] --output_root [compressed_video_path]

This script will compress the video to 3fps with width 224 (or height 224). Modify the variables for your customization.

Text-Video Retrieval

Train on MSR-VTT 1k

Protocol T2V R@1 T2V R@5 T2V R@10 Mean R
EMCL-Net (2 V100 GPUs) 47.0 72.6 83.0 13.6
EMCL-Net (8 V100 GPUs) 48.2 74.7 83.6 13.1

We recommend using more GPUs for better performance:

CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 \
python -m torch.distributed.launch \
--master_port 2502 \
--nproc_per_node=8 \

--datatype msrvtt \
--max_words 32 \
--max_frames 12 \
--video_framerate 1 \
--output_dir ${OUTPUT_PATH}

You can also use 2 V100 GPUs to reproduce the results in the paper:

CUDA_VISIBLE_DEVICES=0,1 \
python -m torch.distributed.launch \
