recommend installing pytorch and python packages using Anaconda
- cuda
- pytorch 0.4.0
- python3
- ffmpeg (can install using anaconda)
- tqdm
- pillow
- pretrainedmodels
- nltk
MSR-VTT. Test video doesn't have captions, so I spilit train-viedo to train/val/test. Extract and put them in ./data/ directory
- train-video: download link
- test-video: download link
- json info of train-video: download link
- json info of test-video: download link
UPDATE: MSR-VTT. Test video have released captions. You can download the all captions from baiduyun pwd: nxyk. There are also many extracted features in baiduyun.
- all_videodatainfo_2017.json: json info of train-video and test-video
- c3d_feat: c3d_kintectics(16f) and so on
- 2d_feat: resnet101 and nasnet
- audio_feat: extracted by tensorflow/models/research/audioset/
- proposal_feat: extracted by Detectron
all default options are defined in opt.py or corresponding code file, change them for your like.
Some code refers to ImageCaptioning.pytorch
you can use video-classification-3d-cnn-pytorch to extract features from video.
- preprocess videos and labels
python prepro_feats.py --output_dir data/feats/resnet152 --model resnet152 --n_frame_steps 40 --gpu 4,5
python prepro_vocab.py- Training a model
python train.py --gpu 0 --epochs 3001 --batch_size 300 --checkpoint_path data/save --feats_dir data/feats/resnet152 --model S2VTAttModel --with_c3d 1 --c3d_feats_dir data/feats/c3d_feats --dim_vid 4096-
test
opt_info.json will be in same directory as saved model.
python eval.py --recover_opt data/save/opt_info.json --saved_model data/save/model_1000.pth --batch_size 100 --gpu 1I fork the coco-caption XgDuan. Thanks to port it to python3.

You can see my another repository video-caption-openNMT.py. It has higher performence and test score.
