Hello!
Where did you get "yolov4-tiny-detection.py"？
OpenVINO start to use "import ngraph as ng" from OpenVINO 2021.2,And i provided the inference demo here : https://github.com/TNTWEN/OpenVINO-YOLOV4/blob/master/pythondemo/2021.2/object_detection_demo_yolov3_async.py

If your OpenVINO version is 2020.4 or 2021.1 you should use: https://github.com/TNTWEN/OpenVINO-YOLOV4/tree/master/pythondemo/2020.4 and https://github.com/TNTWEN/OpenVINO-YOLOV4/tree/master/pythondemo/2021.1
