🌟 Summary

Improved dataset checking and automatic download logic in YOLOv5 utilities.

📊 Key Changes

• Simplified YAML file reading using a new yaml_load function.
• Enhanced path resolution for dataset files, fixing potential path issues.
• Dataset auto-download now places files in a predefined DATASETS_DIR.

🎯 Purpose & Impact

🎁 Purpose:

• To streamline the loading of dataset configurations by using a custom function.
• To ensure dataset paths are correctly resolved, regardless of their initial relative path format.
• To standardize the location of automatically downloaded datasets for better organization and consistency.

🚀 Impact:

• Users will experience more reliable dataset loading with fewer path-related errors.
• Automatic downloads become more predictable and less prone to clutter the user's directories.
• Overall improvements to dataset management may simplify both development and user experience.
