# Hugging Face Dataset Exporter
This script exports data from a Postgres database to a Hugging Face dataset in Parquet format.
## Setup
1. **Install dependencies:**
Navigate to this directory and install the required Python packages.
```bash
pip install -r requirements.txt
```
2. **Set environment variables:**
The script uses environment variables for database credentials. You can set them in your shell or use a `.env` file.
```bash
export DB_USER="your_db_user"
export DB_PASSWORD="your_db_password"
export DB_HOST="localhost"
export DB_PORT="5432"
export DB_NAME="your_db_name"
```
## Usage
Run the script from the root of the repository:
```bash
python scripts/hf_export/export.py --output_dir /path/to/your/dataset
```
The script will create a directory at the specified output path containing the dataset in Parquet format. If `--output_dir` is not provided, it will save to `hf_dataset` in the current working directory. |
