🌟 Summary

Improved device compatibility for Automatic Mixed Precision (AMP) in YOLOv5.

📊 Key Changes

• AMP is now explicitly disabled on both CPU and Metal Performance Shaders (MPS) devices.

🎯 Purpose & Impact

• 🎯 Purpose: To prevent users from attempting to use AMP on devices that don't support it, which are now specified as CPU and MPS, enhancing code robustness.
• 💥 Impact: Ensures better stability and clarity for users working on different hardware, as attempting to use AMP on unsupported devices would likely result in errors or suboptimal performance.
