🌟 Summary

Improvement of version checking in YOLOv5 with backward compatibility handling.

📊 Key Changes

• Added check_version function call in yolo.py for grid creation compatible with PyTorch versions >=1.10.0.
• Enforced a strict version requirement for the albumentations library in augmentations.py.
• Updated the check_version function in general.py to include an option to enforce hard version checks.

🎯 Purpose & Impact

• Ensures YOLOv5 accommodates changes in PyTorch's meshgrid function, maintaining compatibility with different versions. 🔄
• Prevents running YOLOv5 with incompatible versions of dependencies which could lead to unexpected errors, by enforcing hard version checks where necessary. 🔒
• Users benefit from clear error messages when their environment does not meet the version requirements, improving the user experience and ease of troubleshooting. 🛠️
