CoralNet-Toolbox 🪸🧰

AI-Powered Annotation for Coral Reef Analysis. An unofficial toolkit to supercharge your CoralNet workflows.

⚡ Get Started

1. Create Conda Environment (Recommended)

# Create and activate custom environment
conda create --name coralnet10 python=3.10 -y
conda activate coralnet10

# Install uv
pip install uv

2. (Optional) GPU Acceleration If you have an NVIDIA GPU with CUDA, install PyTorch with CUDA support for full acceleration.

# Example for CUDA 12.9; use your version of CUDA
uv pip install torch torchvision --index-url https://download.pytorch.org/whl/cu129

3. Install

# Use UV for the fastest installation
uv pip install coralnet-toolbox

Fallback: If UV fails, use regular pip: pip install coralnet-toolbox

4. Launch

coralnet-toolbox

See the Installation Guide for details on other versions.

🌍 About CoralNet

Coral reefs are among Earth's most biodiverse ecosystems, supporting marine life and coastal communities worldwide. However, they face unprecedented threats from climate change, pollution, and human activities.

CoralNet is a revolutionary platform enabling researchers to:

• Upload and analyze coral reef photographs
• Create detailed species annotations
• Build AI-powered classification models
• Collaborate with the global research community

The CoralNet-Toolbox extends this mission by providing advanced AI tools that accelerate research and improve annotation quality.
