## 🛠️ PR Summary

<sub>Made with ❤️ by [Ultralytics Actions](https://github.com/ultralytics/actions)<sub>

### 🌟 Summary
Enhanced YOLOv5 validation script for streamlined inference.

### 📊 Key Changes
- Removed `time_sync` function import from `utils.torch_utils` in the `val.py` script.

### 🎯 Purpose & Impact
- 🎯 **Purpose:** Streamlining the validation code by eliminating unnecessary utilities, potentially reducing clutter and confusion within the codebase.
- 💡 **Impact:** Users may experience a slight increase in clarity when navigating the validation script, although the change is minimal and may not have a noticeable impact on the end-user experience. Developers will have a cleaner codebase to work with, ensuring that only essential utilities are imported.
