| ## Environment Setup | |
| The competition environment uses Python 3.12.7 and includes a comprehensive set of dependencies listed in [requirements.txt](requirements.txt). The contestants were not allowed to install other external libraries, so these were the only packages they could use. Below are instructions for setting up the environment using different package managers. | |
| ### Using Conda (Recommended) | |
| ```bash | |
| # Create and activate a new conda environment | |
| conda create -n ioai-2025 python=3.12.7 | |
| conda activate ioai-2025 | |
| # Update pip and install dependencies | |
| pip install --upgrade pip | |
| pip install --no-deps -r requirements.txt | |
| ``` | |
| ### Using venv | |
| ```bash | |
| # Linux/macOS | |
| python3.12 -m venv ioai-2025 | |
| source ioai-2025/bin/activate | |
| # Windows | |
| python -m venv ioai-2025 | |
| .\ioai-2025\Scripts\activate | |
| # Install dependencies (all platforms) | |
| pip install --upgrade pip | |
| pip install --no-deps -r requirements.txt | |
| ``` | |
| ### Using pyenv | |
| ```bash | |
| # Install Python 3.12.7 | |
| pyenv install 3.12.7 | |
| pyenv local 3.12.7 | |
| # Create and activate virtual environment | |
| python -m venv .venv | |
| source .venv/bin/activate # Linux/macOS | |
| .\.venv\Scripts\activate # Windows | |
| # Install dependencies | |
| pip install --upgrade pip | |
| pip install --no-deps -r requirements.txt | |
| ``` | |
| > **Note**: The `--no-deps` flag is required to ensure exact package versions match the competition environment. | |
