pip install -r requirement.txt

Dataset setup

Please download the dataset here and refer to VideoPose3D to set up the Human3.6M dataset ('./dataset' directory).

${POSE_ROOT}/
|-- dataset
|   |-- data_3d_h36m.npz
|   |-- data_2d_h36m_gt.npz
|   |-- data_2d_h36m_cpn_ft_h36m_dbb.npz

Download pretrained model

The pretrained model is here, please download it and put it in the './ckpt/pretrained' directory.

Test the model

To test on Human3.6M on single frame, run:

python main.py --reload --previous_dir "ckpt/pretrained"

Train the model

To train on Human3.6M with single frame, run:

python main.py --train -n 'name'

To begin, download the YOLOv3 and HRNet pretrained models here and put it in the './demo/lib/checkpoint' directory. Next, download the pretrained model and put it in the './ckpt/pretrained' directory. Lastly, Put your own images in the './demo/figure', and run:

python demo/vis.py
