ultralytics 8.3.25

v8.3.25 - `ultralytics 8.3.25` Alibaba MNN export and predict support (#16802)

on Python PyPI

🌟 Summary

The v8.3.25 release of Ultralytics brings a major update with the introduction of support for the Alibaba MNN (Mobile Neural Network) format, enabling better deployment of YOLO models on mobile and embedded systems.

📊 Key Changes

• Alibaba MNN Support: Added the ability to export and predict with YOLO models in the MNN format.
• Integration Updates: Documentation and integration guides have been enhanced to include MNN details.
• Improved ONNX Runtime: The ONNX Runtime has been optimized for faster inference, reducing overheads and improving performance, allowing for efficient handling of dynamic and static shape inferences.
• Tracking Improvements: Lowered default confidence thresholds for trackers to align with detection predictions, facilitating better tracking performance.

🎯 Purpose & Impact

• Enhanced Mobile Deployment: With MNN support, users can deploy models with high efficiency on mobile and ARM devices, allowing for more versatile applications.
• Performance Optimization: Faster ONNX inference ensures reduced runtime and improved speed, which is particularly beneficial for applications requiring real-time processing.
• User-Friendly: Updated thresholds for tracking models now provide more intuitive operations, aligning the outputs of tracking systems with user expectations.
• Streamlined Updates: Improved configuration and integration steps reduce friction during the setup of modern AI workflows, enhancing overall usability and user satisfaction.
