🌟 Summary

Refinement of logging and error messaging in YOLOv5's download and creation functions.

📊 Key Changes

• Introduced environment variable YOLOv5_VERBOSE to control verbosity.
• Changed certain print statements to LOGGER.info for better control over logging.
• Used the LOGGER variable within the download functions for consistent logging.
• Modified method signatures to use _verbose instead of verbose where appropriate.

🎯 Purpose & Impact

• 🔧 Consistent Verbosity Control: The use of the YOLOv5_VERBOSE environment variable provides unified verbosity control across different parts of the code.
• 📝 Enhanced Logging: Transitioning from print to LOGGER.info offers developers a more granular logging level, which can help with debugging.
• 🧰 Developer Experience: Improved error handling and messaging during the download process can make development and troubleshooting smoother for users working with YOLOv5’s codebase.
• 🔄 Minimal User Impact: Changes are largely under-the-hood; end users working with YOLOv5 models may notice more informative logging during installation or when errors occur, but overall functionality remains the same.

Test code:

import torch

# Model
model = torch.hub.load('ultralytics/yolov5:update/verbose_hub', 'yolov5s', verbose=False)

# Images
dir = 'https://ultralytics.com/images/'
imgs = [dir + f for f in ('zidane.jpg', 'bus.jpg')]  # batch of images

# Inference
results = model(imgs)
results.print()  # or .show(), .save()

Test fails, all output still seen in console. Seems that our custom verbose argument conflicts with the default torch hub verbose argument. https://pytorch.org/docs/stable/hub.html#torch.hub.load

@glenn-jocher how about we rename our argument to yolo_verbose?

[glenn-jocher]

@Powercube7 I can try that!
