Export your model for use with mobile devices
Custom Vision Service allows classifiers to be exported to run offline. You can embed your exported classifier into an application and run it locally on a device for real-time classification.
Custom Vision Service supports the following exports:
- Tensorflow for Android.
- CoreML for iOS11.
- ONNX for Windows ML.
- A Windows or Linux container. The container includes a Tensorflow model and service code to use the Custom Vision Service API.
Custom Vision Service only exports compact domains. The models generated by compact domains are optimized for the constraints of real-time classification on mobile devices. Classifiers built with a compact domain may be slightly less accurate than a standard domain with the same amount of training data.
For information on improving your classifiers, see the Improving your classifier document.
Convert to a compact domain
The steps in this section only apply if you have an existing classifier that is not set to compact domain.
To convert the domain of an existing classifier, use the following steps:
Select a project, and then select the Gear icon in the upper right of the page.
In the Domains section, select a compact domain. Select Save Changes to save the changes.
From the top of the page, select Train to retrain using the new domain.
Export your model
To export the model after retraining, use the following steps:
Go to the Performance tab and select Export.
If the Export entry is not available, then the selected iteration does not use a compact domain. Use the Iterations section of this page to select an iteration that uses a compact domain, and then select Export.
Select the export format, and then select Export to download the model.
Integrate your exported model into an application. Several sample applications are available:
- A sample for using your exported CoreML model in an iOS application for real-time image classification with Swift
- Sample iOS application for using your exported CoreML model with Xamarin for real-time image classification
- Sample for using your exported Tensorflow model in an Android application for real-time image classification
- Using your Tensorflow model with Windows
- Sample for using your exported ONNX model with Windows Machine Learning
