Our model can be learnt in a single GPU V100-32G
conda env create -f environment.yml
conda activate T2M-GPTThe code was tested on Python 3.8 and PyTorch 1.8.1.
bash dataset/prepare/download_glove.shWe are using two 3D human motion-language dataset: HumanML3D and KIT-ML. For both datasets, you could find the details as well as download link [here].
Take HumanML3D for an example, the file directory should look like this:
./dataset/HumanML3D/
├── new_joint_vecs/
├── texts/
├── Mean.npy # same as in [HumanML3D](https://github.com/EricGuo5513/HumanML3D)
├── Std.npy # same as in [HumanML3D](https://github.com/EricGuo5513/HumanML3D)
├── train.txt
├── val.txt
├── test.txt
├── train_val.txt
└── all.txt
We use the same extractors provided by t2m to evaluate our generated motions. Please download the extractors.
bash dataset/prepare/download_extractor.shThe pretrained model files will be stored in the 'pretrained' folder:
bash dataset/prepare/download_model.shIf you want to render the generated motion, you need to install:
sudo sh dataset/prepare/download_smpl.sh
conda install -c menpo osmesa
conda install h5py
conda install -c conda-forge shapely pyrender trimesh mapbox_earcutA quick start guide of how to use our code is available in demo.ipynb
Note that, for kit dataset, just need to set '--dataname kit'.
The results are saved in the folder output.

Follow the evaluation setting of text-to-motion, we evaluate our model 20 times and report the average result. Due to the multimodality part where we should generate 30 motions from the same text, the evaluation takes a long time.

You should input the npy folder address and the motion names. Here is an example:
python3 render_final.py --filedir output/TEST_GPT/ --motion-list 000019 005485We appreciate helps from :
- public code like text-to-motion, TM2T, MDM, MotionDiffuse etc.
- Mathis Petrovich, Yuming Du, Yingyi Chen, Dexiong Chen and Xuelin Chen for inspiring discussions and valuable feedback.
- Minh Chien Vu for the hugging face space demo.
- 2023/02/19 add the hugging face space demo for both skelton and SMPL mesh visualization.
