Microsoft Azure Custom Vision Client Library for Python

No—do not install for new projects. The package is deprecated and will receive no maintenance after 11-01-2024. If you have an existing project already using this SDK, it will continue to work, but you should plan a migration to a current Azure Vision SDK. For new work, use a supported Azure SDK or alternative vision service.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a valid Azure Custom Vision endpoint URL and API key; credentials must be wrapped in msrest.authentication.ApiKeyCredentials, not passed as a plain string.
- Low install friction with four stable Azure dependencies.
- However, the package is deprecated as of 11-01-2024 and will receive only security fixes—no new features or maintenance beyond that date.

What it is and what it does
This is the official Python SDK for Microsoft Azure's Custom Vision service, allowing developers to programmatically train image classification and object detection models without writing machine learning code from scratch. The package wraps Azure's REST API, providing client classes for both training (building and managing models) and prediction (running inference on trained iterations). It depends on msrest, azure-common, azure-mgmt-core, and azure-cognitiveservices-vision-nspkg to handle authentication, HTTP communication, and Azure SDK conventions.
The package has been deprecated as of 11-01-2024 and will no longer receive maintenance or feature updates after that date. If you are starting a new project, Microsoft recommends migrating to a newer Azure Vision service SDK. Existing projects using this package will continue to work, but you should plan for eventual migration or accept that you will not receive updates beyond security patches.
Use it for
- Train a custom image classifier to recognize specific product types in retail inventory photos.
- Build an object detection model to locate and count items in warehouse or manufacturing environments.
- Programmatically manage multiple Custom Vision projects and iterations without using the web portal.
- Export trained models for deployment to edge devices or containers as part of a CI/CD pipeline.
