Autodistill uses big, slower foundation models to train small, faster supervised models. Using
autodistill, you can go from unlabeled images to inference on a custom model running at the edge with no human intervention in between.
Here are example predictions of a Target Model detecting milk bottles and bottlecaps after being trained on an auto-labeled dataset using Autodistill (see the Autodistill YouTube video for a full walkthrough):
- 🔌 Pluggable interface to connect models together
- 🤖 Automatically label datasets
- 🐰 Train fast supervised models
- 🔒 Own your model
- 🚀 Deploy distilled models to the cloud or the edge
📚 Basic Concepts¶
autodistill, you input unlabeled data into a Base Model which uses an Ontology to label a Dataset that is used to train a Target Model which outputs a Distilled Model fine-tuned to perform a specific Task.
Autodistill defines several basic primitives:
- Task - A Task defines what a Target Model will predict. The Task for each component (Base Model, Ontology, and Target Model) of an
autodistillpipeline must match for them to be compatible with each other. Object Detection and Instance Segmentation are currently supported through the
classificationsupport will be added soon.
- Base Model - A Base Model is a large foundation model that knows a lot about a lot. Base models are often multimodal and can perform many tasks. They're large, slow, and expensive. Examples of Base Models are GroundedSAM and GPT-4's upcoming multimodal variant. We use a Base Model (along with unlabeled input data and an Ontology) to create a Dataset.
- Ontology - an Ontology defines how your Base Model is prompted, what your Dataset will describe, and what your Target Model will predict. A simple Ontology is the
CaptionOntologywhich prompts a Base Model with text captions and maps them to class names. Other Ontologies may, for instance, use a CLIP vector or example images instead of a text caption.
- Dataset - a Dataset is a set of auto-labeled data that can be used to train a Target Model. It is the output generated by a Base Model.
- Target Model - a Target Model is a supervised model that consumes a Dataset and outputs a distilled model that is ready for deployment. Target Models are usually small, fast, and fine-tuned to perform a specific task very well (but they don't generalize well beyond the information described in their Dataset). Examples of Target Models are YOLOv8 and DETR.
- Distilled Model - a Distilled Model is the final output of the
autodistillprocess; it's a set of weights fine-tuned for your task that can be deployed to get predictions.
💡 Theory and Limitations¶
Human labeling is one of the biggest barriers to broad adoption of computer vision. It can take thousands of hours to craft a dataset suitable for training a production model. The process of distillation for training supervised models is not new, in fact, traditional human labeling is just another form of distillation from an extremely capable Base Model (the human brain 🧠).
Foundation models know a lot about a lot, but for production we need models that know a lot about a little.
As foundation models get better and better they will increasingly be able to augment or replace humans in the labeling process. We need tools for steering, utilizing, and comparing these models. Additionally, these foundation models are big, expensive, and often gated behind private APIs. For many production use-cases, we need models that can run cheaply and in realtime at the edge.
Autodistill's Base Models can already create datasets for many common use-cases (and through creative prompting and few-shotting we can expand their utility to many more), but they're not perfect yet. There's still a lot of work to do; this is just the beginning and we'd love your help testing and expanding the capabilities of the system!
Autodistill is modular. You'll need to install the
autodistill package (which defines the interfaces for the above concepts) along with Base Model and Target Model plugins (which implement specific models).
By packaging these separately as plugins, dependency and licensing incompatibilities are minimized and new models can be implemented and maintained by anyone.
pip install autodistill autodistill-grounded-sam autodistill-yolov8

Frequently Asked Questions ❓¶
What causes the
PytorchStreamReader failed reading zip archive: failed finding central directory error?¶
This error is caused when PyTorch cannot load the model weights for a model. Go into the
~/.cache/autodistill directory and delete the folder associated with the model you are trying to load. Then, run your code again. The model weights will be downloaded from scratch. Leave the installation process uninterrupted.
