🌟 Summary

Streamlined Python package publishing process for improved compatibility and efficiency.

📊 Key Changes

• Updated GitHub Actions workflow for package publishing.
• Removed in-place editable install (-e .) combined with Ultralytics package, ensuring a more standard installation process.
• Added explicit uninstallation of older thop versions to prevent conflicts.
• Reordered installation commands for clarity and efficiency.

🎯 Purpose & Impact

• Enhanced Compatibility: By uninstalling conflicting older thop versions before installation, this change ensures that the latest version of thop from this repository doesn't face installation issues. This is particularly useful for users who need the latest features and fixes.
• Streamlined Installation Process: Splitting the installation process (removing the combination of editable install with the Ultralytics package) makes the GitHub Action more readable and easier to maintain, potentially speeding up the publishing process and reducing errors.
• Efficiency and Reliability: These changes aim to make the package release process more efficient and reliable, ultimately providing users with quicker access to stable releases.

🔄 Overall, these adjustments make the package more user-friendly and the development process smoother, benefiting both the maintainers and end-users of the thop package.
