- 06/27/2022: The pretrained models of 27, 81, 243, and 351 frames are all released!
- 03/24/2022: Demo and in-the-wild inference code are released!
- Create a conda environment:
conda create -n mhformer python=3.9
- Install PyTorch 1.7.1 and Torchvision 0.8.2 following the official instructions
pip3 install -r requirements.txt
Please download the dataset from Human3.6M website and refer to VideoPose3D to set up the Human3.6M dataset ('./dataset' directory). Or you can download the processed data from here.

| |-- data_2d_h36m_gt.npz
| |-- data_2d_h36m_cpn_ft_h36m_dbb.npz
The pretrained model can be found in here, please download it and put it in the './checkpoint/pretrained' directory.
To test on a 351-frames pretrained model on Human3.6M:
python main.py --test --previous_dir 'checkpoint/pretrained/351' --frames 351
Here, we compare our MHFormer with recent state-of-the-art methods on Human3.6M dataset. Evaluation metric is Mean Per Joint Position Error (MPJPE) in mm​.
Models | MPJPE |
---|---|
VideoPose3D | 46.8 |
PoseFormer | 44.3 |
MHFormer | 43.0 |
To train a 351-frames model on Human3.6M:
python main.py --frames 351 --batch_size 128
To train a 81-frames model on Human3.6M:
python main.py --frames 81 --batch_size 256
First, you need to download YOLOv3 and HRNet pretrained models here and put it in the './demo/lib/checkpoint' directory. Then, you need to put your in-the-wild videos in the './demo/video' directory.
Run the command below:
python demo/vis.py --video sample_video.mp4
