INT8 Calibration (calib.table) Not Generated on Jetson Orin Nano

[shubham07-rapidise]

I am trying to run DeepStream-YOLO with a YOLOv8 INT8 model on Jetson Orin Nano. I followed the official calibration steps as described in the Ultralytics DeepStream guide (https://docs.ultralytics.com/guides/deepstream-nvidia-jetson/), but the INT8 calibration table (calib.table) is not being generated. DeepStream crashes with a segmentation fault during engine build. I want to run multiple stream with smooth & lowest latency, so I thats why im trying to generate int8 engine model.
