🎨 Gradio Demo

Launch Demo Locally (Video dance generation demo is on the way!)

1. Download the fine-tuning checkpoint model (our demo uses this checkpoint, you can also use your own model); Download the sd-image-variation via git clone https://huggingface.co/lambdalabs/sd-image-variations-diffusers.

2. Run the jupyter notebook file. All the required code/command are already set up. Remember to revise the pretrained model path --pretrained_model and --pretrained_model_path (sd-va) in manual_args = [xxx].

3. After running, this jupyter will automatically launch the demo with your local dev GPU. You can visit the demo with the web link provided at the end of the notebook.

4. Or you can refer to our deployment with Colab . All the code are deployed from scratch!

📝 Introduction

In this project, we introduce DisCo as a generalized referring human dance generation toolkit, which supports both human image & video generation with multiple usage cases (pre-training, fine-tuning, and human-specific fine-tuning), especially good in real-world scenarios.

✨Compared to existing works, DisCo achieves:

• Generalizability to a large-scale real-world human without human-specific fine-tuning (We also support human-specific fine-tuning). Previous methods only support generation for a specific domain of human, e.g., DreamPose only generate fashion model with easy catwalk pose.

• Current SOTA results for referring human dance generation.

• Extensive usage cases and applications (see project page for more details).

• An easy-to-follow framework, supporting efficient training (x-formers, FP16 training, deepspeed, wandb) and a wide range of possible research directions (pre-training -> fine-tuning -> human-specific fine-tuning).

🌟With this project, you can get:

• [User]: Just try our online demo! Or deploy the model inference locally.
• [Researcher]: An easy-to-use codebase for re-implementation and development.
• [Researcher]: A large amount of research directions for further improvement.

Data Preparation

1. Human Attribute Pre-training

We create a human image subset (700K Images) filtered from existing image corpus for human attribute pre-training:

Dataset	COCO (Single Person)	TikTok Style	DeepFashion2	SHHQ-1.0	LAION-Human
Size	20K	124K	276K	40K	240K

The pre-processed pre-training data with the efficient TSV data format can be downloaded here (Google Drive).

Data Root
└── composite/
    ├── train_xxx.yaml  # The path need to be then specified in the training args
    └── val_xxx.yaml
    ...
└── TikTokDance/
    ├── xxx_images.tsv
    └── xxx_poses.tsv
    ...
└── coco/  
    ├── xxx_images.tsv
    └── xxx_poses.tsv

2. Fine-tuning with Disentangled Control

We use the TikTok dataset for the fine-tuning.

We have already pre-processed the tiktok data with the efficient TSV format which can be downloaded here (Google Drive). (Note that we only use the 1st frame of each TikTok video as the reference image.)

The data folder structure should be like:

Data Root
└── composite_offset/
    ├── train_xxx.yaml  # The path need to be then specified in the training args
    └── val_xxx.yaml
    ...
└── TikTokDance/
    ├── xxx_images.tsv
    └── xxx_poses.tsv
    ...

*PS: If you want to use your own data resource but with our TSV data structure, please follow PREPRO.MD for reference.

Fine-tuning with Disentangled Control

1. Modify the config file

Download the sd-image-variations-diffusers from official diffusers repo and put it according to the config file pretrained_model_path. Or you can also choose to modify the pretrained_model_path.

2. w/o Classifier-Free Guidance (CFG)

Training:

[*To enable WANDB, set up the wandb key in utils/lib.py]

[*To employ multiple GPU running, try to add mpirun -np {GPU NUM} before the python.]

--combine_clip_local --combine_use_mask \
--conds "poses" "masks" \
--stage1_pretrain_path /path/to/pretrained_model_checkpoint/mp_rank_00_model_states.pt 

Visualization:

To run the visualization, just change --do_train to --eval_visu . You can also specify the visualization folder name with '--eval_save_filename' xxx.

Evaluation:

You first need to run the evaluation to get the results. Then we use gen_eval.sh to one-stop get the evaluation metrics for {exp_dir_path}/{prediction_folder_name}

bash gen_eval.sh {exp_dir_path} {exp_dir_path}/{prediction_folder_name}

For example,

bash gen_eval.sh /home/kevintw/code/disco/github2/DisCo/save_results/TikTok_cfg_check /home/kevintw/code/disco/github2/DisCo/save_results/TikTok_cfg_check/pred_gs1.5_scale-cond1.0-ref1.0/

You may need to download the pre-trained vision model and revise the path in gen_eval.sh for achieving fvd metric.

3. w/ Classifier-Free Guidance (CFG) [CFG can bring a slightly better results]

Training (add the following args into the training script of w/o CFG):

--drop_ref 0.05 # probability to dropout the reference image during training
--guidance_scale 1.5 # the scale of the CFG

Visualization:

To run the visualization, just change --do_train to --eval_visu . You can also specify the visualization folder name with '--eval_save_filename' xxx. (Remember to also specify the --guidance_scale)

You can also check our command bash file config/command_bash/tiktok_cfg.sh for reference.

Evaluation:

Same with above

4. Temporal module fine-tuning

Training: After training the image DisCo model, we further incorporate temporal convolutional layers and temporal attention layers to improve the temporal smoothness. Note that the content for argument --pretrained_model should be the image DisCo model checkpoint, instead of stage 1 pre-trained checkpoint.

AZFUSE_USE_FUSE=0 NCCL_ASYNC_ERROR_HANDLING=0 python finetune_sdm_yaml.py --cf config/disco_w_tm/yz_tiktok_S256L16_xformers_tsv_temdisco_temp_attn.py \

--epochs 20 --deepspeed \
--eval_step 500 --save_step 500 \
--gradient_accumulate_steps 1 \
--learning_rate 1e-4 --fix_dist_seed --loss_target "noise" \
--train_yaml /home/wangtan/data/disco/yaml_file/train_TiktokDance-poses-masks.yaml \

--nframe 16 \
--frame_interval 1 \
--conds "poses" "masks" \
--pretrained_model /path/to/pretrained_model/mp_rank_00_model_states.pt 

Evaluation: Simply replace the previous gen_eval.sh script with the gen_eval_tm.sh script, as follows. GT folder path will be filled in automatically.

bash gen_eval_tm.sh {exp_dir_path} {exp_dir_path}/{prediction_folder_name}

5. Possible issue for FVD metric reproduction

Please first check the github issue and response here. We have validated the checkpoint results on A100 GPU. If you still cannot reproduce the results, please open an issue or send me the email.

Human-Specific Fine-tuning

1. Prepare dataset that you want to use for training

• Prepare a human-specific video or a set of human images

• Use Grounded-SAM and OpenPose to obtain human mask and human skeleton for each training image (See PREPRO.MD for more details)

• For human-specific fine-tuning, we recommend to directly use raw image/mask/pose for training rather than build TSV file. If you still want to use TSV file structure to prepare your data, please follow PREPRO.MD for reference.

2. Run the following script for human-specific fine-tuning:

For parameter tuning, recommend to first tune the learning-rate and unet_unfreeze_type.

AZFUSE_USE_FUSE=0 NCCL_ASYNC_ERROR_HANDLING=0 python finetune_sdm_yaml.py \
--cf config/ref_attn_clip_combine_controlnet_imgspecific_ft/webtan_S256L16_xformers_upsquare.py --do_train --root_dir /path/of/saving/root \
--local_train_batch_size 32 --local_eval_batch_size 32 --log_dir exp/human_specific_ft/ \
--epochs 20 --deepspeed --eval_step 500 --save_step 500 --gradient_accumulate_steps 1 \
--learning_rate 1e-3  --fix_dist_seed  --loss_target "noise" \
--unet_unfreeze_type "crossattn" \
--refer_sdvae --ref_null_caption False --combine_clip_local --combine_use_mask --conds "poses" "masks" \
--freeze_pose True --freeze_background False \

--ft_iters 500 --ft_one_ref_image False --ft_idx dataset/folder/name --strong_aug_stage1 True --strong_rand_stage2 True

Notes

1. Possible issue for FVD metric reproduction

Please first check the github issue and response here. We have validated the checkpoint results on A100 GPU. If you still cannot reproduce the results, please open an issue or send me the email.

2. PSNR metric

We thank @Delicious-Bitter-Melon for for highlighting a potential numerical overflow issue in the implementation of the PSNR metric. This issue has been resolved in codebase, and the updated score is reflected in our latest version. It’s important to note that this correction does not alter the trend or affect the overall conclusions.

3. DisCo is not limited to upper-human.

Please check our latest paper for its generalizability. It can be easily achieved by incorporating extensive image scaling augmentations during the training phase.

Release Plan
