🌟 Summary

Improve robustness of ClearML integration in YOLOv5 logging.

📊 Key Changes

• Wrapped the ClearmlLogger initialization in a try-except block.
• If initialization fails, self.clearml is set to None.
• Added a colored error message prefix indicating an issue with ClearML setup.

🎯 Purpose & Impact

• 🎯 Purpose: To handle cases where ClearML setup is not successful, preventing the entire logging process from failing and providing users with guidance on where to seek help.
• 🚀 Impact: Users will have a clearer indication if there is an issue with ClearML integration, reducing frustration and downtime due to unexpected crashes. It also helps in maintaining logging functionality even if ClearML is not properly set up.
