🌟 Summary

Improvements to notebook initialization in YOLOv5 by ensuring the WandB is uninstalled in certain environments.

📊 Key Changes

• Added a command to uninstall the wandb Python package during the environment setup process.

🎯 Purpose & Impact

• 🎯 Purpose: The main goal seems to cater specifically to environments like Google Colab, where a clean slate is desired for certain dependencies when initializing notebooks. By explicitly uninstalling wandb, it may help avoid potential conflicts or bugs related to WandB that may already be installed in the environment.
• 🎯 Impact: This change will ensure that whenever a user starts up a new instance on platforms like Colab, they won't have wandb installed by default, potentially avoiding version mismatches and streamlining the setup process. Users looking to use wandb will need to reinstall it, which could add an extra step, but ensures that they have the latest and compatible version.
