### 3.1. Prerequisites 🧰
* Python 3.9+
* A Conda environment is highly recommended.
* Python 3.12+
* Dependency management: using uv is recommended for fast, reproducible installs (uv.lock provided). Conda/Python is supported as an alternative.
* Access to EDA tools for generating labeled data (e.g., a DRC engine for hotspot labels).
### 3.2. Installation 🚧
1. **Clone the repository:**
```bash
git clone https://github.com/your-username/Geo-Layout-Transformer.git
cd Geo-Layout-Transformer
```
#### A) Using uv (recommended)
2. **Create and activate the Conda environment:**
```bash
conda create -n geo_trans python=3.9
conda activate geo_trans
```
1) Install uv (one-time):
3. **Install dependencies:**
This project requires PyTorch and PyTorch Geometric (PyG). Please follow the official installation instructions for your specific CUDA version.
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```
* **PyTorch:** [https://pytorch.org/get-started/locally/](https://pytorch.org/get-started/locally/)
* **PyG:** [https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html](https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html)
2) Clone the repository:
After installing PyTorch and PyG, install the remaining dependencies:
```bash
pip install -r requirements.txt
```
*(Note: You may need to install `klayout` separately via its own package manager or build from source to enable its Python API).*
```bash
git clone https://github.com/your-username/Geo-Layout-Transformer.git
cd Geo-Layout-Transformer
```
3) Ensure Python 3.12 is available (uv can manage it):
```bash
uv python install 3.12
```
4) Create the environment and install dependencies from uv.lock/pyproject:
```bash
uv sync
```
Notes:
- For CUDA builds of PyTorch/PyG, follow the official installers first, then install the rest via uv:
- PyTorch: https://pytorch.org/get-started/locally/
- PyG: https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html
After installing the correct Torch/PyG wheels, you may run `uv sync --frozen` to install the remaining packages.
- You may need to install `klayout` separately (package manager or from source) to enable its Python API.
#### B) Using Python/Conda (alternative)
1) Clone the repository:
```bash
git clone https://github.com/your-username/Geo-Layout-Transformer.git
cd Geo-Layout-Transformer
```
2) Create and activate an environment (Conda example):
```bash
conda create -n geo_trans python=3.12
conda activate geo_trans
```
3) Install PyTorch and PyTorch Geometric per your CUDA setup:
- PyTorch: https://pytorch.org/get-started/locally/
- PyG: https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html
4) Install the remaining dependencies:
```bash
pip install -r requirements.txt
```
> Tip: GPU is optional. For CPU-only environments, install the CPU variants of PyTorch/PyG.
> Note: You may need to install `klayout` separately to enable its Python API.

1. Place your layout files in the `data/gds/` directory.
2. Configure the preprocessing parameters in `configs/default.yaml`. You will need to define patch size, stride, layer mappings, and how to construct graph edges.
3. Run the preprocessing script:
```bash
python scripts/preprocess_gds.py --config-file configs/default.yaml --gds-file data/gds/my_design.gds --output-dir data/processed/my_design/
```
- Using uv (recommended):
```bash
uv run python scripts/preprocess_gds.py --config-file configs/default.yaml --gds-file data/gds/my_design.gds --output-dir data/processed/my_design/

- Using Python/Conda:
```bash
python scripts/preprocess_gds.py --config-file configs/default.yaml --gds-file data/gds/my_design.gds --output-dir data/processed/my_design/

This script will parse the GDS file, divide it into patches, construct a graph for each patch, and save the processed data as `.pt` files for efficient loading.

To build a powerful foundation model, we first pre-train it on unlabeled data using a "Masked Layout Modeling" task.
