AI Choreographer: Music Conditioned 3D Dance Generation with AIST++ [ICCV-2021].

Overview

This package contains the model implementation and training infrastructure of our AI Choreographer.

Get started

Pull the code

git clone https://github.com/liruilong940607/mint --recursive

Note here --recursive is important as it will automatically clone the submodule (orbit) as well.

Install dependencies

conda create -n mint python=3.7
conda activate mint
conda install protobuf numpy
pip install tensorflow absl-py tensorflow-datasets librosa

sudo apt-get install libopenexr-dev
pip install --upgrade OpenEXR
pip install tensorflow-graphics tensorflow-graphics-gpu

git clone https://github.com/arogozhnikov/einops /tmp/einops
cd /tmp/einops/ && pip install . -U

git clone https://github.com/google/aistplusplus_api /tmp/aistplusplus_api
cd /tmp/aistplusplus_api && pip install -r requirements.txt && pip install . -U

Note if you meet environment conflicts about numpy, you can try with pip install numpy==1.20.

Get the data

See the website

Get the checkpoint

Download from google drive here, and put them to the folder ./checkpoints/

Run the code

1. complie protocols

protoc ./mint/protos/*.proto

2. preprocess dataset into tfrecord

python tools/preprocessing.py \
    --anno_dir="/mnt/data/aist_plusplus_final/" \
    --audio_dir="/mnt/data/AIST/music/" \
    --split=train
python tools/preprocessing.py \
    --anno_dir="/mnt/data/aist_plusplus_final/" \
    --audio_dir="/mnt/data/AIST/music/" \
    --split=testval

3. run training

python trainer.py --config_path ./configs/fact_v5_deeper_t10_cm12.config --model_dir ./checkpoints

Note you might want to change the batch_size in the config file if you meet OUT-OF-MEMORY issue.

4. run testing and evaluation

# caching the generated motions (seed included) to `./outputs`
python evaluator.py --config_path ./configs/fact_v5_deeper_t10_cm12.config --model_dir ./checkpoints
# calculate FIDs
python tools/extract_aist_features.py 
python tools/calculate_fid_scores.py
