:desktop_computer: Requirements

NVIDIA GPUs are required for this project. We have test the inference codes on NVIDIA RTX2080Ti, NVIDIA V100, NVIDIA A100, NVIDIA T4. The training codes have been tested on NVIDIA V100, NVIDIA A100. We recommend using anaconda to manage the python environments.

conda create --name eva3d python=3.8
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.1 -c pytorch
conda install -c fvcore -c iopath -c conda-forge fvcore iopath
conda install pytorch3d -c pytorch3d

Download Models

The pretrain model and SMPL model are needed for inference.

The following script downloads pretrain models.

python download_models.py

Register and download SMPL models here. Put the downloaded models in the folder smpl_models. Only the neutral one is needed. The folder structure should look like

./
├── ...
└── smpl_models/
    ├── smpl/
        └── SMPL_NEUTRAL.pkl

Commands

We provide a script for inference the model trained on DeepFashion, SHHQ, UBCFashion, AIST.

bash scripts/demo_deepfashion_512x256.sh
bash scripts/demo_shhq_512x256.sh
bash scripts/demo_ubcfashion_512x256.sh
bash scripts/demo_aist_256x256.sh

:train: Training

DeepFashion

Download SMPL Models & Processed Datasets

python download_models.py
python download_datasets.py

Commands

bash scripts/train_deepfashion_512x256.sh

Intermediate results will be saved under checkpoint/train_deepfashion_512x256/volume_renderer/samples every 100 iterations. The first line presents inference images from EMA generator. The second line present one inference sample of the training generator and one sample from the training dataset.

To inference the trained models, please refer to the Inference section.
