CoralNet-Toolbox 🪸🧰
AI-Powered Annotation for Coral Reef Analysis. An unofficial toolkit to supercharge your CoralNet workflows.
Marine imaging technology is advancing rapidly, capturing more data than ever before. To keep pace, the instinct of the tech industry is often to build entirely new, fully automated pipelines that disrupt how scientists naturally work. However, this ignores the reality of ecological research: laboratories already rely on stringent standards, deeply established protocols, and decades of domain expertise. CoralNet-Toolbox recognizes that the goal shouldn't be to force a new way of working, but to respect and protect the processes that already yield rigorous scientific results.
⚡ 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 12.8 for a NVIDIA 5090 (blackwell); use your version of CUDA
uv pip install torch torchvision --index-url https://download.pytorch.org/whl/cu128
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
🎯 GPU Status Indicators

⚠️ Platform-Specific Notes
macOS Users
Version 1.0.0 and greater relies heavily on a package (PyQtADS) that cannot be installed on your operating system. Please do not upgrade from 0.0.105 until this is resolved. Instead, use Docker for installation — see the Installation Guide for details.
🔧 Running into Issues?
Upgrading
# Upgrade coralnet-toolbox only (without upgrading other packages)
uv pip install --upgrade coralnet-toolbox
Note: Using
-Uor--upgrade-allupgrades all packages, which may trigger a regression to the CPU version oftorch. To avoid this, use the command above to upgrade only coralnet-toolbox. If you do experience a regression, usepipto uninstalltorchandtorchvision, then re-install theCUDAversion.
Removing Packages
To remove a problematic package, type the following:
uv pip uninstall package-name-here
Starting Fresh (New Environment)
To delete an old environment and create a fresh one:
# Deactivate if already in the environment
conda deactivate coralnet10
# Delete the old environment
conda env remove --name coralnet10
# Confirm when prompted
y
# Create a new environment (see "Get Started" section above for details)
conda create --name coralnet10 python=3.10 -y
conda activate coralnet10
pip install uv
uv pip install coralnet-toolbox

From Bottleneck to Pipeline
Traditional benthic imagery analysis is time-consuming. Manual annotation, data management, and model training are often separate, complex tasks. CoralNet-Toolbox unifies this process, turning a research bottleneck into an integrated, AI-accelerated pipeline.
