ultralytics 8.3.150

v8.3.150 - `ultralytics 8.3.150` Set default `conf=0.01` for OBB validation (#20923)

on Python PyPI

🌟 Summary

This release streamlines model validation, improves memory efficiency for oriented bounding box (OBB) tasks, enhances documentation clarity, and fixes usability issues in the parking management solution. 🚀

📊 Key Changes

• Validation Improvements: Removed unused progress bar parameters from all validator classes, making the codebase cleaner.
• OBB Validation Optimization: Set the default confidence threshold for OBB validation to 0.01 (up from 0.001) to reduce memory usage.
• Benchmark Consistency: Updated benchmarking utilities to always use a confidence threshold of 0.001 for reliable mAP comparisons.
• Parking Management Fix: Improved image upload handling—users now receive a clear message if no image is selected, preventing errors.
• Documentation Enhancements: Standardized code block formatting and syntax highlighting across all docs for better readability.
• CI Workflow Update: Switched to CPU-only PyTorch (pytorch-cpu) for Conda-based continuous integration tests, ensuring compatibility on machines without GPUs.

🎯 Purpose & Impact

• Cleaner & More Maintainable Code: Removing unused parameters and improving documentation makes the codebase easier to understand and work with for both new and experienced developers. 🧹
• Better Memory Management: The higher default confidence threshold for OBB validation prevents excessive memory consumption, making validation more stable, especially on resource-limited systems. 🧠
• Consistent Benchmarking: Explicitly setting the confidence threshold in benchmarks ensures that performance metrics are comparable and trustworthy. 📈
• Improved User Experience: The parking management solution is now more robust and user-friendly, reducing confusion and preventing errors during image uploads. 🅿️🖼️
• Wider Compatibility: CI tests now run smoothly on CPU-only environments, making it easier for contributors and users without GPUs to build and test Ultralytics software. 💻

Overall, this update delivers a smoother development and user experience, with optimizations that benefit both everyday users and contributors.
