🌟 Summary

Update to dependency versions in requirements.txt for improved compatibility and functionality.

📊 Key Changes

• scipy version requirement: Lowered from >=1.7.3 to >=1.4.1 allowing for greater compatibility with older systems.
• tqdm version requirement: Bumped up from >=4.41.0 to >=4.64.0 for enhanced progress bar features.
• thop version requirement: Increased from >=0.1.0 to >=0.1.1 for more accurate FLOPs (floating point operations per second) computation.

🎯 Purpose & Impact

• Wider Compatibility: The change in scipy version allows older systems to run YOLOv5 without needing to upgrade this package.
• Progress Bar Improvements: The update in tqdm brings new features and fixes to the progress bar utility, enhancing user experience during training and inference.
• Improved FLOPs Calculation: The slight bump in thop version ensures users have access to more precise model complexity measurements, important for optimizing models.

The impact is largely positive, providing users with additional flexibility while ensuring they have the latest features and bug fixes for essential libraries. 💡🔄💻
