🌟 Summary

Enhanced logging verbosity control in YOLOv5 model initialization.

📊 Key Changes

• Added a verbose parameter to the Model class constructor to control the output of the initialization information.
• Modified the parse_model function to accept a verbose argument that determines whether model details are printed during parsing.
• Adjusted logging behavior in both Model initialization and parse_model function to conditionally display logs based on the verbose flag.

🎯 Purpose & Impact

• 🎛️ Enhanced Flexibility: Users can now control the amount of logging information displayed during model initialization, which is useful for keeping console output clean.
• 🧑‍💻 Developer Convenience: The addition of the verbose argument helps developers by providing options to either view detailed initialization logs or minimize noise during development tasks.
• 📉 Potential Impact: This update impacts users who prefer running YOLOv5 without extensive console logging, as they now have the option to limit output, leading to a more streamlined user experience.

@fcakyon thanks for the PR! This was discussed recently in #2862 and the consensus was that we want a global solution based on setting logger levels, i.e. when verbose=True is passed in any function then the logger levels would switch from logging.INFO to logging.WARN. Maybe something like this (the rank is there for multi-GPU DDP):

def set_logging(rank=-1, verbose=True): 
     logging.basicConfig( 
         format="%(message)s", 
         level=logging.INFO if (verbose and rank in [-1, 0]) else logging.WARN) 

One issue is that we'd want this verbose variable to really be a global variable (maybe the logger variable also?) so that's it doesn't need to be passed down to functions as an argument.
