Computational resource consumption

Training

Time and GPU memory consumed for training (single A100 GPU):

	(Stage-1) VQ-VAE	(Stage-2) Part-Coordinated Transformer
Time	20.5h	52.3h
Memory	3.5GB	28.4GB

Inference

Method	Param(M)	FLOPs(G)	InferTime(s)
ReMoDiffuse	198.2	481.0	0.091
T2M-GPT	237.6	292.3	0.544
ParCo (Ours)	168.4	211.7	0.036

For the FLOPs metric, we calculate the FLOPs when the model generates a single motion sample of 200 frames.
We report the time consumed to generate a single sample for the InferTime metric. We generated 10,000 samples and calculated the average inference time per sample. For ReMoDiff and our ParCo, we set the batch size to 100 (T2M-GPT does not support batch parallel inference).

1. Quick Start Demo

1.1. Colab Demo

👉 Try our Colab demo !

Our demo shows how to prepare the environment and inference with ParCo. You can also conveniently explore our ParCo.

If you wish to reproduce the visualization results of ParCo, we recommend installing the environment locally following our tutorial and reproducing it there (as results differ between Colab and local runs). This is likely due to differences in GPU and CUDA environment between Colab and local training/testing.

1.2. Local Quick Inference

After the installation completed, you can directly generate motion (.gif format) with your own text input as following:

CUDA_VISIBLE_DEVICES=0 python visualize/infer_motion_npy.py \
--eval-exp-dir output/ParCo_official_HumanML3D/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--infer-mode userinput \
--input-text 'an idol trainee is dancing like a basketball dribbling.' \
--skip-path-check

The generated motion visual sample is saved as output/visualize/XXXXX-userinput/skeleton_viz.gif.

2. Installation

2.1. Environment

Our model was trained and tested on a single A100-40G GPU with software environment: Python 3.7.11, PyTorch 1.10.1, CUDA 11.3.1, cuDNN 8.2.0, Ubuntu 20.04.

CUDA & cuDNN (cuDNN may not be necessary)

CUDA and cuDNN should be installed first. We use following version: CUDA: 11.3.1 and cuDNN: 8.2.0.
- Install CUDA 11.3:
  1. Download from here (we recommend to choose installer type as runfile (local).
  2. Install the runfile using the scripts given by the official website.
  3. Before running our code, check if your CUDA environment is linked to CUDA 11.3 (run nvcc --version to check). If the version is not 11.3, you need to add the CUDA path into your environment by export PATH=/usr/local/cuda-11.3/bin:$PATH, then check the version again.
- Install cuDNN 8.2.0:
  1. Download from here (select 8.2.0 for CUDA 11.X and cuDNN Library for Linux/Windows according to your system)
  2. Install the cuDNN according to this guide. Refer to Section 2.3.1. Tar File Installation since we download tar file at previous stage.

CUDA_VISIBLE_DEVICES=0 python train_ParCo_vq.py \
--out-dir output \
--exp-name ParCo \
--dataname t2m \
--batch-size 256 \

Remember to set --vqvae-train-dir to the corresponding directory of the VQ-VAE you trained.

For KIT-ML dataset, set --dataname kit.

CUDA_VISIBLE_DEVICES=0 python train_ParCo_trans.py \
--vqvae-train-dir output/00000-t2m-ParCo/VQVAE-ParCo-t2m-default/ \
--select-vqvae-ckpt last \

4. Evaluation

4.1. VQ-VAE

Remember to set --vqvae-train-dir to the VQ-VAE you want to evaluate.

CUDA_VISIBLE_DEVICES=0 python eval_ParCo_vq.py --vqvae-train-dir output/00000-t2m-ParCo/VQVAE-ParCo-t2m-default/ --select-vqvae-ckpt last

4.2. Part-Coordinated Transformer

For evaluation on KIT-ML dataset, set --select-ckpt last. If you want to evaluate the MultiModality (which takes a long time), just delete --skip-mmod.

Remember to set --eval-exp-dir to your trained ParCo's directory.

CUDA_VISIBLE_DEVICES=0 python eval_ParCo_trans.py \
--eval-exp-dir output/00000-t2m-ParCo/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--skip-mmod

5. Pre-trained Models

Our pretrained models are provided at [Google Drive]. Extract the .zip files and put them under output folder for evaluation.

You can also run following scripts to prepare the pretrained models:

mkdir output
cd output
gdown 1jmuX3xDEku3e_ldnTUm192eQRS3EEw99
unzip ParCo_official_model_weights_HumanML3D.zip
cd ..

For model trained on KIT-ML, replace the gdown downloading command with gdown 1_D9vqIhMv5-oz6qfiTGKjsxhS5DNP0PB and unzip command with unzip ParCo_official_model_weights_KIT-ML.zip.

Since we renamed the directory of pre-trained models, remember to set --skip-path-check when evaluating our Part-Coordinated transformer. For example:

CUDA_VISIBLE_DEVICES=0 python eval_ParCo_trans.py \
--eval-exp-dir output/ParCo_official_HumanML3D/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--skip-mmod \
--skip-path-check

6. ParCo with up&low body partition

Our ParCo adopts 6-part partition strategy. If you want to investigate ParCo with upper and lower body partition, run the scripts below.

Details

Training (For KIT dataset, set --dataname kit):

VQ-VAE (Up&Low)

CUDA_VISIBLE_DEVICES=0 python utils/ParCo_uplow/train_ParCo_vq_uplow.py \
--out-dir output \
--exp-name ParCo \
--dataname t2m \
--batch-size 256 \
--lr 2e-4 \
--total-iter 300000 \
--lr-scheduler 200000 \
--vqvae-cfg default \

--depth 3 \
--dilation-growth-rate 3 \
--vq-act relu \
--quantizer ema_reset \
--loss-vel 0.5 \
--recons-loss l1_smooth

Part-Coordinated Transformer (Up&Low)

Remember to set --vqvae-train-dir to the corresponding directory of the VQ-VAE you trained.

CUDA_VISIBLE_DEVICES=0 python utils/ParCo_uplow/train_ParCo_trans_uplow.py \
--vqvae-train-dir output/00000-t2m-ParCo-UpLow/VQVAE-ParCo-t2m-default/ \
--select-vqvae-ckpt last \
--exp-name ParCo \
--pkeep 0.4 \
--batch-size 128 \
--trans-cfg default \
--fuse-ver V1_3 \
--alpha 1.0 \
--num-layers 14 \
--embed-dim-gpt 1024 \
--nb-code 512 \
--n-head-gpt 16 \
--block-size 51 \
--ff-rate 4 \
--drop-out-rate 0.1 \
--total-iter 300000 \
--eval-iter 10000 \
--lr-scheduler 150000 \
--lr 0.0001 \
--dataname t2m \
--down-t 2 \
--depth 3 \
--quantizer ema_reset \
--dilation-growth-rate 3 \
--vq-act relu

Evaluation:

Similar to the scripts of 6-part, just change the running scripts to the scripts under utils/ParCo_uplow/ directory. For example, to evaluate the Part-Coordinated Transformer (Up&Low), the scripts should be:
```
CUDA_VISIBLE_DEVICES=0 python utils/ParCo_uplow/eval_ParCo_trans_uplow.py \
--eval-exp-dir output/00000-t2m-ParCo-UpLow/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--skip-mmod
```
Remember to set --eval-exp-dir to your trained model's directory.

7. Visualize Motion

Render SMPL mesh:

Option-1: Use the tool provided by us (some adopted from T2M-GPT):

Generate motions in .npy format:

The generated results will be saved under output/visualize/.

Choose your preferred mode:

input text by user:

CUDA_VISIBLE_DEVICES=0 python visualize/infer_motion_npy.py \
--eval-exp-dir output/ParCo_official_HumanML3D/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--infer-mode userinput \
--input-text 'an idol trainee is dancing like a basketball dribbling.' \
--skip-path-check

test set as input:

CUDA_VISIBLE_DEVICES=0 python visualize/infer_motion_npy.py \
--eval-exp-dir output/ParCo_official_HumanML3D/VQVAE-ParCo-t2m-default/00000-Trans-ParCo-default \
--select-ckpt fid \
--infer-mode testset \
--skip-path-check

Render the .npy motion file:

Remember to install the packages for rendering (in 2.1. Environment). Set --filedir to your own motion file directory.

The rendered result will be saved at the same directory with your motion file under rendered_motion folder. For example:
```
CUDA_VISIBLE_DEVICES=0 python visualize/render_final.py --filedir output/visualize/00000-userinput/motion.npy 
```
You will get a rendered .gif motion. For example:

Option-2 (Recommended): refer to MLD.
