This is the codebase for the ACM Multi-Media 2022 paper "3D Human Mesh Reconstruction by Learning to Sample Joint Adaptive Tokens for Transformers".

1. set up the environment:

• python: 3.7.12
• pytorch: 1.7.1
• torchvision: 0.8.2
• cuda: 11.0
• pyrender: 0.1.45
• pyopengl: 3.1.6
• joblib: 1.1.0
• pytorch-lightning: 1.1.8
• opencv-python: 4.5.4.60
• pillow: 9.1.1
• loguru: 0.5.3
• yacs: 0.1.8
• scikit-image: 0.19.0
• azureml: 0.2.7
• azureml-core: 1.36.0.post2
• bottleneck

2. run the following command in the ./Learnable-Sampling directory to install:

python setup.py build develop

3. install opendr via pip+git:

pip install git+https://gitlab.eecs.umich.edu/ngv-python-modules/opendr.git

Please prepare the SMPL data following MeshGraphormer and put all the data into ./src/modeling/data/. After doing so, the structure of the directory should be as follows:

$ src
|-- modeling
|   |-- data
|   |   |-- basicModel_f_lbs_10_207_0_v1.0.0.pkl
|   |   |-- basicModel_m_lbs_10_207_0_v1.0.0.pkl
|   |   |-- basicModel_neutral_lbs_10_207_0_v1.0.0.pkl
|   |   |-- J_regressor_extra.npy
|   |   |-- J_regressor_h36m_correct.npy

1. Download the tsv datasets following METRO and put the downloaded files into ./data/datasets/.
2. Download the db file and the evaluation config file for the 3DPW dataset from https://cloud.tsinghua.edu.cn/d/2da7d016fedb42de8039/ and put them into ./data/datasets/db/. Note that you should download the original images of the 3DPW dataset from the official webset and prepare them following the key 'image_name' in the db file.
3. Download the pretrained models from https://cloud.tsinghua.edu.cn/d/bc66b120bd5847649622/ and put them into ./data/pretrained_models/.
4. Download the trained checkpoints from https://cloud.tsinghua.edu.cn/d/61ba08aec1664798b7b6/ and put them into ./data/checkpoints/.
5. After doing the above four steps, the structure of the ./data directory should be as follows:

$ data  
|-- datasets  
|   |-- Tax-H36m-coco40k-Muco-UP-Mpii
|   |-- human3.6m
|   |-- coco_smpl
|   |-- muco
|   |-- up3d
|   |-- mpii
|   |-- 3dpw
|   |-- db
|   |   |-- 3dpw_test_db.pt
|   |   |-- test_3dpw.yaml
|-- pretrained_models
|   |-- pose_coco
|   |   |-- pose_hrnet_w32_256x192.pth
|   |   |-- pose_hrnet_w64_256x192.pth
|   |   |-- pose_resnet_50_256x192.pth
|   |-- pare_checkpoint.ckpt
|-- checkpoints
|   |-- 3dpw_checkpoint.bin
|   |-- h36m_checkpoint.bin

To evaluate on 3DPW dataset, please run the following command:

python src/tools/main.py \
       --num_workers 1 \
       --config_yaml experiments/3dpw_config.yaml \
       --val_yaml data/datasets/db/test_3dpw.yaml \
       --per_gpu_eval_batch_size 10 \
       --output_dir ./output/ \
       --run_eval_only \
       --resume_checkpoint data/checkpoints/3dpw_checkpoint.bin

To evaluate on H36M dataset, please run the following command:

python src/tools/main.py \
       --num_workers 1 \
       --config_yaml experiments/h36m_config.yaml \
       --val_yaml data/datasets/human3.6m/valid.protocol2.yaml \
       --per_gpu_eval_batch_size 10 \
       --output_dir ./output/ \
       --run_eval_only \
       --resume_checkpoint data/checkpoints/h36m_checkpoint.bin

Training instructions will come soon.
