Installation
The experiments are conducted on Ubuntu 16.04, with Python version 3.6.9, and PyTorch version 1.0.1.post2.
To setup the environment:
cd PoseAug
conda create -n poseaug python=3.6.9
conda activate poseaug
pip install -r requirements.txtPrepare dataset
- Please refer to
DATASETS.mdfor the preparation of the dataset files.
Run training code
- There are 32 experiments in total (16 for baseline training, 16 for PoseAug training), including four pose estimators (SemGCN, SimpleBaseline, ST-GCN, VideoPose) and four 2D pose settings (Ground Truth, CPN, DET, HR-Net).
- The training procedure contains two steps: pretrain the baseline models and then train these baseline models with PoseAug.
To pretrain the baseline model,
# gcn
python3 run_baseline.py --note pretrain --dropout 0 --lr 2e-2 --epochs 100 --posenet_name 'gcn' --checkpoint './checkpoint/pretrain_baseline' --keypoints gt
python3 run_baseline.py --note pretrain --dropout 0 --lr 2e-2 --epochs 100 --posenet_name 'gcn' --checkpoint './checkpoint/pretrain_baseline' --keypoints cpn_ft_h36m_dbb

# videopose

python3 run_baseline.py --note pretrain --dropout -1 --lr 1e-3 --posenet_name 'stgcn' --checkpoint './checkpoint/pretrain_baseline' --keypoints hr
# Note: for st-gcn, dropout is set to -1, representing the default dropout setting used in the original code (different layers using different dropout values).
To train the baseline model with PoseAug:
# gcn
python3 run_poseaug.py --note poseaug --dropout 0 --posenet_name 'gcn' --lr_p 1e-3 --checkpoint './checkpoint/poseaug' --keypoints gt
python3 run_poseaug.py --note poseaug --dropout 0 --posenet_name 'gcn' --lr_p 1e-3 --checkpoint './checkpoint/poseaug' --keypoints cpn_ft_h36m_dbb

python3 run_poseaug.py --note poseaug --dropout 0 --posenet_name 'stgcn' --lr_p 1e-4 --checkpoint './checkpoint/poseaug' --keypoints hr
All the checkpoints, evaluation results and logs will be saved to ./checkpoint. You can use tensorboard to monitor the training process:
cd ./checkpoint/poseaug
tensorboard --logdir=/path/to/eventfileComment:
- For simplicity, hyper-param for different 2D pose settings are the same. If you want to explore better performance for specific setting, please try changing the hyper-param.
- The GAN training may collapse, change the hyper-param (e.g., random_seed) and re-train the models will solve the problem.
Run evaluation code
python3 run_evaluate.py --posenet_name 'videopose' --keypoints gt --evaluate '/path/to/checkpoint'We provide a checkpoint/PoseAug_result_summary.ipynb, which can generate the result summary table for all 16 experiments.
