- This is the official repository of VALOR which provides training&testing code and pretraining checkpoints.
- VALOR-32K dataset (annotation) can be downloaded from project page. Raw videos can be downloaded from YouTube.
- VALOR-1M will be released after paper is accepted.
- Paper w audio files embeded in PDF can be found on project page.
- We have proposed a stronger vision-audio-subtitle-text omni-modality foundation model (VAST), Paper, Github page.
- We have proposed a new strong video-language pretraining model (COSA), Paper, Code.
- VALOR is implemented based on Pytorch. We use pytorch-1.9.0 and cuda-11.1. Other version could be also compatible.
pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html
- build apex.
cd apex
pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
- install needed packages.
sh preinstall.sh
- pretrained_weights (BERT,CLIP,VideoSwin). Put pretrained_weights dir under main path. (VALOR/pretrained_weights)
- VALOR models.
| Model | Pretrained Ckpt | Finetuned Ckpt on MSRVTT-Retrieval | Finetuned Ckpt on MSRVTT-Caption |
|---|---|---|---|
| VALOR-B | VALOR-base | VALOR_base_msr_ret.pt | VALOR_base_msr_cap.pt |
| VALOR-L | VALOR-large | VALOR_large_msr_ret.pt | VALOR_large_msr_cap.pt |
Put VALOR-base and VALOR-large under the output dir. (VALOR/output/VALOR-base, VALOR/output/VALOR-large)
VALOR is pretrained and tested on multiple vision-language, audio-language and audiovisual-language datasets. e.g. PRETRAIN: VALOR-1M, WebVid-2.5M, CC-3M (VALOR-base) TEST: VALOR-32K, MSRVTT, MSVD, DiDeMo, LSMDC, ActivityNet, VATEX, AudioCaps, ClothoV1, TGIF-Frame, MSCOCO, VQAV2... We here take MSRVTT as an example to show the data processing procedures, other datasets take a similar way.
- make dir VALOR/datasets/MSRVTT
- download raw videos from website, and put them in MSRVTT/raw_videos
- extract video frames (.jpg) and audio files (.wav). Utilizing utils/extract_frame_and_wav_multiprocess.py (Note: VALOR use this offline extracted frames and audios for training and testing for it's fast I/O speed. You may adjust to read raw videos via decord library, and need to change VideoMapper and AudioMapper classes in data/data.py.)
- prepare id_files (standardsplit_train_id.json, standardsplit_test_id.json, 1KAsplit_train_id.json, 1KAsplit_test_id.json). The format is List(Str) ['video0', 'video1', ...]. The former two are for video captioning and video qa, while the latter two are for video retrieval.
- prepare txt_mapper.json. txt_mapper files map videoIDs to its descriptions. Format {'video0':['desc1','desc2',...'desc20']}. For VideoQA task, the format is {'video0':[{'question':'what color is ...?', 'answer':'red'},{'question':'Is the boy ...?', 'answer':'yes'}]}
- prepare caption_annotation.json. This file is used for computing caption metrics. format: [{'video_id':'video0','caption','A boy is ...'}, {'video_id':'video1','caption','A girl is ...'}]
The processed dataset path should be as follows:

│ ├── msrvtt
│ │ ├── raw_videos
│ │ │ ├── video0.mp4
│ │ │ └── video1.mp4
│ │ ├── frames_fps4
│ │ │ ├── video0

│ │ ├── txt_mapper_1kAsplit_test.json
│ │ ├── txt_mapper_vqa.json
│ │ └── caption_annotation.json
We provide processed json files for most finetuneing datasets here, and you only need to download and extract raw videos of each dataset.
- finetune retrieval tasks
sh scripts/finetune_ret.sh $pretrain_path(output/VALOR_base)
- finetune captioning tasks
sh scripts/finetune_cap.sh $pretrain_path(output/VALOR_base)
- finetune QA tasks
sh scripts/finetune_qa.sh $pretrain_path(output/VALOR_base)
The finetuning output path will be the subdir of $pretrain_path
For example, the cmd for finetuning retrieval model in scripts/finetune_ret.sh is as follows:
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python -m torch.distributed.launch --nproc_per_node=8 --master_port 32711 ./train.py \
--pretrain_dir $basedir \
--config ./config/fast-retrieval-msrvtt.json \
--output_dir $basedir'/ret-msrvtt-lr2e-5-bs64-epoch5' \
--learning_rate 2e-5 \
--train_video_sample_num 4 \
--test_video_sample_num 8 \
--save_best true \
if you want to test model, just add following two rows to the cmd:
--zero_shot \
--checkpoint $checkpoint_save_path(.pt)
sh scripts/pretrain.sh
VALOR's framework is easy to expand new tasks/datasets. what you need to do is
- prepare dataset as illustrated above
- write config file (copy a config file and change 'data_cfg')
-
In development stage, you can simply use cmd to overwrite config file. The most important args are : --learning_rate --train_batch_size --train_video_sample_num --test_video_sample_num --train_audio_sample_num --test_audio_sample_num --video_resolution --train_epoch --train_task --test_task
-
To control task and used modality group, you can rewrite train_task by 'task%modality_group1%modality_group2' For example: finetuning text-to-audio retrieval 'ret%ta' finetuning text-to-video retrieval 'ret%tv' or 'ret%tva'
-
Other settings --fp16 (default: True) --checkpointing (default: False)
