torch-uncertainty 0.10.1

Uncertainty quantification in PyTorch

TorchUncertainty is a package designed to help leverage uncertainty quantification techniques to make deep neural networks more reliable. It aims at being collaborative and including as many methods as possible, so reach out to add yours!

:construction: TorchUncertainty is in early development :construction: - expect changes, but reach out and contribute if you are interested in the project! Please raise an issue if you have any bugs or difficulties and join the discord server.

:books: Our webpage and documentation is available here: torch-uncertainty.github.io. :books:

TorchUncertainty contains the official implementations of multiple papers from major machine-learning and computer vision conferences and was featured in tutorials at WACV 2024, HAICON 2024 and ECCV 2024.

Torch-Uncertainty is published at NeurIPS D&B 2025. Please consider citing the paper if the framework is helpful for your research.

This package provides a multi-level API, including:

• easy-to-use :zap: lightning uncertainty-aware training & evaluation routines for 4 tasks: classification, probabilistic and pointwise regression, and segmentation.
• fully automated evaluation of the performance of models with proper scores, selective classification, out-of-distribution detection and distribution shift performance metrics!
• ready-to-train baselines on research datasets, such as ImageNet and CIFAR
• layers, models, metrics, & losses available for your networks
• scikit-learn style post-processing methods such as Temperature Scaling.
• transformations and augmentations, including corruptions resulting in additional "corrupted datasets" available on HuggingFace

Have a look at the Reference page or the API reference for a more exhaustive list of the implemented methods, datasets, metrics, etc.

:gear: Installation

TorchUncertainty requires Python 3.10 or greater. Install the desired PyTorch version in your environment. Then, install the package from PyPI:

pip install torch-uncertainty

The installation procedure for contributors is different: have a look at the contribution page.

:whale: Docker image for contributors

For contributors running experiments on cloud GPU instances, we provide a pre-built Docker image that includes all necessary dependencies and configurations and the Dockerfile for building your custom Docker images. This allows you to quickly launch an experiment-ready container with minimal setup. Please refer to DOCKER.md for further details.

:racehorse: Quickstart

We make a quickstart available at torch-uncertainty.github.io/quickstart.
