Datamint Python API

Build Status Python 3.10+

Datamint turns medical imaging ML work. Dataset management, annotation, training, and deployment into a few lines of Python, with built-in support for DICOM/NIfTI/PNG, PyTorch Lightning trainers, and MLflow tracking.

Common use cases: 🩻 Segmentation · 🏷️ Classification · 📦 Detection

Datamint handles the full journey from raw files to a deployed model:

🚀 Features

  • Dataset Management: Download, upload, and manage medical imaging datasets using intuitive object-based APIs or CLI tools
  • Annotation Tools: Create, upload, and manage annotations (segmentations, labels, measurements) with ease
  • Experiment Tracking: Seamless support for experiment management via MLflow integration
  • One-line Trainers: Train segmentation, classification, and detection models with built-in PyTorch Lightning trainers, skipping the dataset class, training loop, and logging setup
  • Model Benchmarking: Compare several trainers against the same dataset and split, and get a ranked leaderboard of their performance
  • DICOM Support: Native handling of DICOM files, including powerful anonymization capabilities during upload to protect patient privacy
  • Multi-format Support: Robust support for a wide range of medical imaging formats: PNG, JPEG, NIfTI (NIfTI/NRRD), DICOMs and more

⚡ Quick Start

1. Install

pip install -U datamint

Using a virtual environment (recommended)

We recommend that you install Datamint in a dedicated virtual environment, to avoid conflicting with your system packages. For instance, create the enviroment once with python3 -m venv datamint-env and then activate it whenever you need it with:

  1. Create the environment (one-time setup):

    python3 -m venv datamint-env

  2. Activate the environment (run whenever you need it):

    Platform Command
    Linux/macOS source datamint-env/bin/activate
    Windows CMD datamint-env\Scripts\activate.bat
    Windows PowerShell datamint-env\Scripts\Activate.ps1

  3. Install the package:

    pip install datamint

2. Configure your API key

datamint config

Follow the prompts (ask your administrator if you don't have a key yet). Environment variable and programmatic options are in the Setup API Key guide.

3. Scaffold a project — the fastest way to start

datamint init

This is the recommended on-ramp: it asks for a project name and task type (segmentation, classification, or detection), then generates a ready-to-run, numbered set of scripts (01_upload_data.py → 06_deploy.py) — upload data, train, and deploy by running them in order.

4. ...or write it yourself

from datamint import Api
from datamint.lightning import UNetPPTrainer

api = Api()
api.projects.create(name="my-project", exists_ok=True)

trainer = UNetPPTrainer(project="my-project")
results = trainer.fit()
