ultralytics 8.2.48

v8.2.48 - `ultralytics 8.2.48` strip model `criterion` on save (#14106)

on Python PyPI

🌟 Summary

A minor update with key improvements and refinements to model loading and processing.

📊 Key Changes

• Improved Error Messaging: Updated error and warning messages to generalize references from "YOLOv8" models to "Ultralytics" models.
• Model Verification: Enhanced checks to ensure files are valid Ultralytics models before processing.
• Stripping Optimizer Function: Added and refined steps within the strip_optimizer function:
  • Replaced model with Exponential Moving Average (EMA) if available.
  • Stripped unnecessary components (optimizer, loss criterion, etc.) to reduce file size.
  • Converted specific attributes to ensure compatibility and effective usage.

🎯 Purpose & Impact

• Improved Clarity: The changes in messaging make it clearer for users regardless of which version of the model they are using, reducing potential confusion.
• Efficient Model Handling: By verifying model validity and stripping non-essential parts, the update ensures smoother operations and smaller file sizes, potentially leading to faster loading times and less storage usage.
• Enhanced Flexibility: The refined error and warning messages allow for a more robust handling of various model scenarios, increasing the flexibility and robustness of the software for users.
