🌟 Summary

Enhanced support for batch processing in YOLOv5 inference when using specific model formats.

📊 Key Changes

• Added condition to check if the input model format is .xml and the input image batch size is greater than 1.
• Implemented chunking of the input image tensor into individual images for sequential processing.
• Changed the model prediction step to handle each image separately for .xml model formats when batch size is greater than 1.
• Assembled individual predictions into a single batch after processing.

🎯 Purpose & Impact

• 🎨 Improves compatibility with .xml model formats that may not support batch inference.
• 🚀 Enables correct inference by processing each image in a sequence rather than as a batch for specific models.
• 🔍 Ensures users can still leverage batch-processing benefits for other formats, while providing a workaround for .xml formatted models.
• 🛠 Potentially increases inference time for .xml models with batches but ensures functional and accurate predictions.
