Pandora: Towards General World Model with Natural Language Actions and Video States

We introduce Pandora, a step towards a General World Model (GWM) that:

1. Simulates world states by generating videos across any domains
2. Allows any-time control with actions expressed in natural language

Please refer to world-model.ai for results.

News

• [2024/05/23] Release the model and inference code.
• [2024/05/23] Launch the website and release the paper.

Setup

conda create -n pandora python=3.11.0 nvidia/label/cuda-12.1.0::cuda-toolkit -y
conda activate pandora
pip install torch torchvision torchaudio
bash build_envs.sh  

If your GPU doesn't support CUDA 12.1, you can also install with CUDA 11.8:

conda create -n pandora python=3.11.0 nvidia/label/cuda-11.8.0::cuda-toolkit -y 
conda activate pandora
pip install torch torchvision torchaudio
bash build_envs.sh  

Inference

Gradio Demo

1. Download the model checkpoint from Hugging Face. (We currently hide the model weights due to data license issue. We will re-open the weights soon after we figure this out.)
2. Run the commands on your terminal

CUDA_VISIBLE_DEVICES={cuda_id} python gradio_app.py  --ckpt_path {path_to_ckpt}

Then you can interact with the model through gradio interface.
