jetson nano部署yolov5使用csi摄像头

jetson nano部署yolov5使用csi摄像头，opencv-python版本4.5.1，输入python3 detect.py --source=0,csi摄像头只打开了一瞬间，就关闭了
报错

File "detect.py", line 282, in <module>
    detect()
  File "detect.py", line 75, in detect
    dataset = LoadStreams(source, img_size=imgsz, stride=stride)
  File "/media/jetson/5C79-7DA0/yolov5-5.1-2/yolov_/utils/datasets.py", line 284, in __init__
    assert cap.isOpened(), f'Failed to open {s}'
AssertionError: Failed to open camera

这是为什么啊

；

摄像头没权限，打开权限试试。
