Welcome to the ONNX Model Zoo! The Open Neural Network Exchange (ONNX) is an open standard format created to represent machine learning models. Supported by a robust community of partners, ONNX defines a common set of operators and a common file format to enable AI developers to use models with a variety of frameworks, tools, runtimes, and compilers.

This repository is a curated collection of pre-trained, state-of-the-art models in the ONNX format. These models are sourced from prominent open-source repositories and have been contributed by a diverse group of community members. Our aim is to facilitate the spread and usage of machine learning models among a wider audience of developers, researchers, and enthusiasts.

To handle ONNX model files, which can be large, we use Git LFS (Large File Storage). To download any model from this collection, please navigate to the specific model's GitHub page and click the "Download" button located in the top right corner, or visit the ONNX Model Zoo website.

Our Model Zoo covers a variety of use cases including:

• Computer Vision
• Natural Language Processing (NLP)
• Generative AI
• Graph Machine Learning

These models are sourced from prominent open-source repositories such as timm, torchvision, torch_hub, and transformers, and exported into the ONNX format using the open-source TurnkeyML toolchain.

There are multiple ways to access the ONNX Model Zoo:

The Model Zoo webpage provides a user-friendly interface to browse models based on use case, author, or by searching for specific model names. It also offers a direct download option for your convenience.

Cloning the repository using git won't automatically download the ONNX models due to their size. To manage these files, first, install Git LFS by running:

pip install git-lfs

To download a specific model:

git lfs pull --include="[path to model].onnx" --exclude=""

To download all models:

git lfs pull --include="*" --exclude=""

Alternatively, you can download models directly from GitHub. Navigate to the model's page and click the "Download" button on the top right corner.

For a graphical representation of each model's architecture, we recommend using Netron.
