Hi @Paul_Siewert
Is it an object detection model based on yolo that you compiled to hef using the settings from the .alls file? Please check what is the output tensor from the model? If it already has Hailo’s NMS postprocessor, you should not apply our postprocessor again. Please see this guide: User Guide 3: Simplifying Object Detection on a Hailo Device Using DeGirum PySDK
