| # Model Introduction |
|
|
| AURORA is a foundation model of the Earth system developed by Microsoft Research. It addresses a range of Earth system prediction tasks, including global weather forecasting and air pollution prediction. The paper was published at ICML 2024. |

|
|
| # Model Description |
|
|
| Aurora is a deep learning model with 1.3 billion parameters, composed of a 3D Perceiver encoder, a 3D Swin Transformer processor, and a 3D Perceiver decoder. |
|
|
| # Use Cases |
|
|
| | Scenario | Description | |
| | :---: | :--- | |
| | Weather Forecast Training | Train AURORA using ERA5 HDF5 data | |
| | Local Quick Validation | Use synthetic data to verify data loading, model training, fine-tuning, inference, and inference result visualization. | |
| | ModelScope / OneCode Execution | Download as a standalone model package, install dependencies, and run scripts directly. | |
| | Multi-GPU Training | Launch multi-process training via `torchrun`. | |

|
| ## 2. Manual Installation and Usage |
|
|
| **Hardware Requirements** |
|
|
| - A GPU or DCU is recommended. |
| - CPU can be used for import and small-scale connectivity verification; full training and inference will be slow. |
| - DCU users must install DTK in advance. DTK 25.04.2 or above, or the OneScience recommended version matching your cluster, is recommended. |
|
|
| ### Download the Model Package |
|
|
| ```bash |
| hf download OneScience-Group/AURORA --local-dir ./AURORA |
| cd AURORA |
| ``` |
|
|
| ### Install the Runtime Environment |
|
|
| **DCU Environment** |
|
|
| ```bash |
| # Please activate DTK and CONDA first |
| conda create -n onescience311 python=3.11 -y |
| conda activate onescience311 |
| # uv installation is supported |
| pip install onescience[earth-dcu] -i http://mirrors.onescience.ai:3141/pypi/simple/ --trusted-host mirrors.onescience.ai |
| ``` |
|
|
| **GPU Environment** |
|
|
| ```bash |
| # Please activate CONDA first |
| conda create -n onescience311 python=3.11 -y libstdcxx-ng=12 libgcc-ng=12 gcc_linux-64=12 gxx_linux-64=12 |
| conda activate onescience311 |
| # uv installation is supported |
| pip install onescience[earth-gpu] -i http://mirrors.onescience.ai:3141/pypi/simple/ --trusted-host mirrors.onescience.ai |
| ``` |
|
|
| ### Training Data Introduction |
|
|
| The OneScience community provides ERA5 data for training (due to file size limits, the current repository contains a slice of the full dataset). Users can download it with the command below and confirm that the data path in `conf/config.yaml` is set correctly: |
|
|
| ```bash |
| hf download --repo-type dataset OneScience-Group/ERA5 --local-dir ./data |
| ``` |
|
|
| ### Generate Synthetic Data for Pipeline Validation |
|
|
| Synthetic data is only used to verify the data protocol and end-to-end pipeline; it does not represent forecast quality: |
|
|
| ```bash |
| python scripts/fake_data.py |
| ``` |
|
|
| ### Training |
|
|
| Single GPU: |
|
|
| ```bash |
| python scripts/train.py |
| ``` |
|
|
| Multi-GPU: |
|
|
| The command below launches 2 training processes on one machine, each using a single device. |
|
|
| ```bash |
| torchrun --nproc_per_node=2 --nnodes=1 --rdzv_id=1000 --rdzv_backend=c10d --max_restarts=0 --master_addr="localhost" --master_port=29500 scripts/train.py |
| ``` |
|
|
| ### Fine-tuning |
|
|
| The configuration points `training.finetune.checkpoint` to `data/checkpoint/model_bak.pt` produced during training, so fine-tuning uses the trained model by default. |
|
|
| ```bash |
| python scripts/finetune.py |
| ``` |
|
|
| ### Training Weights |
|
|
| This repository provides weights trained on ERA5 reanalysis data in the `weights/` folder. The weight files will be uploaded soon and are expected to be available in the near future. |
|
|
| ### Inference |
|
|
| Inference reads `data/checkpoint/model_finetune.pt` saved by fine-tuning by default. |
|
|
| ```bash |
| python scripts/inference.py |
| ``` |
|
|
| ### Evaluation and Visualization |
|
|
| ```bash |
| python scripts/result.py |
| ``` |
