>**Abstract:** 3D human motion generation is crucial for creative industry. Recent advances rely on generative models with domain knowledge for text-driven motion generation, leading to substantial progress in capturing common motions. However, the performance on more diverse motions remains unsatisfactory. In this work, we propose **ReMoDiffuse**, a diffusion-model-based motion generation framework that integrates a retrieval mechanism to refine the denoising process.



    

    



>**Pipeline Overview:** ReMoDiffuse is a retrieval-augmented 3D human motion diffusion model. Benefiting from the extra knowledge from the retrieved samples, ReMoDiffuse is able to achieve high-fidelity on the given prompts. It contains three core components: a) **Hybrid Retrieval** database stores multi-modality features of each motion sequence. b) Semantics-modulated transformer incorporates several identical decoder layers, including a **Semantics-Modulated Attention (SMA)** layer and an FFN layer. The SMA layer will adaptively absorb knowledge from both retrived samples and the given prompts. c) **Condition Mxture** technique is proposed to better mix model's outputs under different combinations of conditions.

## Data Preparation

Download data files from google drive [link](https://drive.google.com/drive/folders/13kwahiktQ2GMVKfVH3WT-VGAQ6JHbvUv?usp=sharing) or Baidu Netdisk [link](https://pan.baidu.com/s/1604jks-9PtBUtqCpQQmeEg)(access code: vprc). Unzipped all files and arrange them in the following file structure:

```text

├── tools

├── configs

├── logs

```

## Training

### Training with a single / multiple GPUs

```shell

PYTHONPATH=".":$PYTHONPATH python tools/train.py ${CONFIG_FILE} ${WORK_DIR} --no-validate

```

**Note:** The provided config files are designed for training with 8 gpus. If you want to train on a single gpu, you can reduce the number of epochs to one-fourth of the original.

### Training with Slurm

```shell

./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${WORK_DIR} ${GPU_NUM} --no-validate

```

Common optional arguments include:

- `--resume-from ${CHECKPOINT_FILE}`: Resume from a previous checkpoint file.

- `--no-validate`: Whether not to evaluate the checkpoint during training.

Example: using 8 GPUs to train ReMoDiffuse on a slurm cluster.

```shell

./tools/slurm_train.sh my_partition my_job configs/remodiffuse/remodiffuse_kit.py logs/remodiffuse_kit 8 --no-validate

```

## Evaluation

### Evaluate with a single GPU / multiple GPUs

```shell

PYTHONPATH=".":$PYTHONPATH python tools/test.py ${CONFIG} --work-dir=${WORK_DIR} ${CHECKPOINT}

```

### Evaluate with slurm

```shell

./tools/slurm_test.sh ${PARTITION} ${JOB_NAME} ${CONFIG} ${WORK_DIR} ${CHECKPOINT}

```

Example:

```shell

./tools/slurm_test.sh my_partition test_remodiffuse configs/remodiffuse/remodiffuse_kit.py logs/remodiffuse_kit logs/remodiffuse_kit/latest.pth

```

**Note:** Run full evaluation for HumanML3D dataset is very slow. You can change `replication_times` in [human_ml3d_bs128.py](configs/_base_/datasets/human_ml3d_bs128.py) to $1$ for a quick evaluation.

## Visualization

```shell

PYTHONPATH=".":$PYTHONPATH python tools/visualize.py ${CONFIG} ${CHECKPOINT} \

    --text ${TEXT} \

    --motion_length ${MOTION_LENGTH} \

    --out ${OUTPUT_ANIMATION_PATH} \

    --device cpu

```

Example:

```shell

PYTHONPATH=".":$PYTHONPATH python tools/visualize.py \

    configs/remodiffuse/remodiffuse_t2m.py \

    logs/remodiffuse/remodiffuse_t2m/latest.pth \

    --text "a person is running quickly" \

    --motion_length 120 \

    --out "test.gif" \

    --device cpu

```
