🌟 Summary

Refined image display logic in the YOLOv5 repository.

📊 Key Changes

• Removed the check_imshow function check from the models/common.py file.
• Simplified the image display logic within the _run method to check if it's running in a notebook environment directly.
• Eliminated an assertion from check_imshow in utils/general.py, which checked for non-interactive environments like SSH terminals or GitHub CI.

🎯 Purpose & Impact

• 🎨 Enhances compatibility by streamlining how images are displayed, directly checking if the code is executed within a notebook.
• 🛠️ Improves maintainability by reducing the complexity of the code related to image visualization.
• 🚀 Ensures that end-users experience seamless image displays while using notebooks, and developers have a clearer codebase.

The modifications pave the way for a smoother experience when displaying images in different environments, particularly important for those interfacing with the YOLOv5 model through interactive notebooks.
