This guide covers the installation of the EOPF GeoZarr library and its dependencies.

Requirements

  • Python 3.11 or higher
  • Operating System: Linux, macOS, or Windows

Installation Methods

Install the latest stable version from PyPI:

bash pip install eopf-geozarr

Using uv (Fast Alternative)

If you have uv installed:

bash uv add eopf-geozarr

Development Installation

For development or to get the latest features:

bash git clone https://github.com/eopf-explorer/data-model.git cd data-model pip install -e .

Dependencies

The library automatically installs the following key dependencies:

  • pydantic-zarr (≥0.8.0) - Zarr data validation
  • zarr (≥3.1.1) - Zarr format support
  • xarray (≥2025.7.1) - N-dimensional labeled arrays
  • dask (≥2025.5.1) - Parallel computing
  • rioxarray (≥0.13.0) - Geospatial xarray extension
  • s3fs (≥2024.6.0) - S3 filesystem support
  • pyproj (≥3.7.0) - Cartographic projections

Optional Dependencies

Development Tools

For development work, install additional tools:

bash pip install eopf-geozarr[dev]

This includes:

  • Testing frameworks (pytest, pytest-cov)
  • Code formatting (black, isort)
  • Linting (flake8, mypy)
  • Security scanning (bandit, safety)

Documentation

To build documentation locally:

bash pip install eopf-geozarr[docs]

Verification

Verify your installation by running:

bash eopf-geozarr --version

Or in Python:

python import eopf_geozarr print(eopf_geozarr.__version__)

Cloud Storage Setup

AWS S3 Configuration

For S3 support, configure your AWS credentials:

```bash

Using AWS CLI

aws configure

Or set environment variables

export AWS_ACCESS_KEY_ID=your_access_key export AWS_SECRET_ACCESS_KEY=your_secret_key export AWS_DEFAULT_REGION=us-east-1 ```

Alternative S3-Compatible Storage

For other S3-compatible services (MinIO, DigitalOcean Spaces, etc.):

bash export AWS_ENDPOINT_URL=https://your-endpoint.com export AWS_ACCESS_KEY_ID=your_access_key export AWS_SECRET_ACCESS_KEY=your_secret_key

Troubleshooting

Common Issues

ImportError: No module named 'eopf_geozarr'

  • Ensure you're using the correct Python environment
  • Verify installation with pip list | grep eopf-geozarr

Permission errors during installation

  • Use pip install --user eopf-geozarr for user-level installation
  • Or use a virtual environment (recommended)

Dependency conflicts

  • Create a fresh virtual environment
  • Use pip install --upgrade eopf-geozarr to update dependencies

Virtual Environment Setup

Recommended approach using venv:

bash python -m venv eopf-env source eopf-env/bin/activate # On Windows: eopf-env\Scripts\activate pip install eopf-geozarr

System-Specific Notes

macOS with Apple Silicon

  • Some dependencies may require Rosetta 2 or native ARM builds
  • Consider using conda for better compatibility

Windows

  • Ensure Visual C++ Build Tools are installed for some dependencies
  • Use Windows Subsystem for Linux (WSL) for best compatibility

Next Steps

After installation, proceed to the Quick Start guide to begin using the library.
