v8.3.76 - `ultralytics 8.3.76` fix `dynamic` batch inference with NMS export (#19249)

on Python PyPI

🌟 Summary

The release of Ultralytics v8.3.76 introduces improved dynamic batch inference for ONNX models with NMS export, a better object tracking experience, and various code and documentation enhancements. 🚀

📊 Key Changes

• Dynamic Batch Improvements:

  • Solved issues with dynamic=True and nms=True where the batch size was fixed at export.
  • Enabled dynamic input handling by introducing padding for unmatched batch sizes during ONNX exports.

• Tracking Enhancements:

  • Addressed errors when processing Torch tensors in model.track().
  • Improved integration of original input images with trackers for accuracy.

• Performance Accuracy:

  • Fixed GPU memory conversion errors for logging VRAM usage to ensure accurate reporting.

• Documentation Updates:

  • Standardized formatting in documentation for better consistency.
  • Enhanced examples for interpreting prediction results across detection, pose, segmentation, and more.

• Other Code Refinements:

  • Addressed layer miscount in logging by ensuring layers with no parameters are also displayed.
  • Enhanced GitHub issue templates for clearer differentiation between bug reports and feature requests.

🎯 Purpose & Impact

• 🛠 Improved Model Deployment: Dynamic padding during export ensures robust handling of varying batch sizes while maintaining compatibility with ONNX workflows.
• 🎥 Better Tracking: Smoother operation for streamed data and enhanced consistency in object tracking results benefit both developers and end-users.
• 📋 Accurate Logging: Correct VRAM usage metrics improve debugging and resource optimization.
• 📚 Developer Friendliness: Updated docs and examples make it easier for users to understand and utilize prediction results effectively.
• 🚀 Efficiency Boost: Code tweaks and fixes culminate in faster, more accurate model handling without disruptions.

This release addresses several community-reported issues, focusing on operational accuracy and usability across export, tracking, and development workflows! 🙌
