Summary

🛠️📝🚀

Refactor utils.general module by using check_requirements function from ultralytics.yolo.utils.checks and format set_logging function. Improve code quality, readability, and modularity.

Oh we're the coders of the sea, and we work with skill and pride
We refactor and we format, to make our code more tidy
We import check_requirements from the checks module
And we heave away, me hearties, on the count of three, heave ho!

Walkthrough

• Import the check_requirements function from the ultralytics.yolo.utils.checks module to use the updated version (link)
• Remove the redundant check_requirements function from the utils.general module to avoid code duplication (link)
• Add a space after the comma in the handlers and loggers dictionaries in the set_logging function to follow the PEP 8 style guide (link)

🌟 Summary

Update dependency checking process and add ultralytics to requirements.

📊 Key Changes

• Modified the dependency checking process by specifying the path to requirements.txt directly in various train.py scripts.
• Added ultralytics as a dependency in the requirements.txt file.
• Removed the check_requirements function from utils/general.py, as it's now handled by ultralytics.yolo.utils.checks.

🎯 Purpose & Impact

• Ensures that the correct path to requirements.txt is used when checking for required packages, improving reliability. 🛠️
• The inclusion of ultralytics in requirements.txt streamlines the setup process for users, ensuring that a specific version of the Ultralytics package is installed. 🚀
• Cleaning up utils/general.py by removing redundant code makes maintenance easier and reduces potential confusion for developers. 🧹

These changes aim to simplify the setup for end-users and maintain a cleaner codebase for developers.
