Core ML Tools

Use coremltools to convert machine learning models from third-party libraries to the Core ML format. The Python package contains the supporting tools for converting models from training libraries such as the following:

With coremltools, you can do the following:

  • Convert trained models to the Core ML format.
  • Read, write, and optimize Core ML models.
  • Verify conversion/creation (on macOS) by making predictions using Core ML.

After conversion, you can integrate the Core ML models with your app using Xcode.

Version 5

The coremltools 5 package offers several performance improvements over previous versions, including the following new features:

  • Core ML model package: A new model container format that separates the model into components and offers more flexible metadata editing and better source control.
  • ML program: A new model type that represents computation as programmatic instructions, offers more control over the precision of its intermediate tensors and better performance.

To install coremltools, use the following command:

pip install coremltools

Core ML

Core ML is an Apple framework to integrate machine learning models into your app. Core ML provides a unified representation for all models. Your app uses Core ML APIs and user data to make predictions, and to fine-tune models, all on the user’s device. Core ML optimizes on-device performance by leveraging the CPU, GPU, and Neural Engine while minimizing its memory footprint and power consumption. Running a model strictly on the user’s device removes any need for a network connection, which helps keep the user’s data private and your app responsive.
