Hi @zhangningboo, normally the jetson-inference/jetson-utils python modules get installed under /usr/lib/python3.8/dist-packages, so I'm confused why the errors are showing /home/nvidia/.local/lib/python3.8/site-packages in your case.

What does running the command below show on your system?

$ ls /usr/lib/python3.8/dist-packages/
cv2/                          jetson/                       jetson_inference_python.so    numpy/                        uff/
graphsurgeon/                 Jetson/                       jetson_utils/                 tensorrt/                     uff-0.6.9.dist-info/

hi, I first install jeson_interferce project, and I meat this error: ImportError: cannot import name 'videoSource' from 'jetson_utils'. than i download jetson_utils project, then rebuild jetson_utils.

[zhangningboo]

jetson-utils maybe conflict with jetson-stats ?

it's working!

OK thanks, I don't know what this other jetson_utils is but that is unfortunate.

[zhangningboo]

And how can I rotate a USB camera image 90 degrees? Thanks for your work!

# video0 = videoSource('v4l2:///dev/video0', ['-input-width=640', '–input-height=480', '-input-codec=mjpeg', '-flip-method=rotate-180'])
# video1 = videoSource('v4l2:///dev/video2', ['-input-width=640', '–input-height=480', '-input-codec=mjpeg', '-input-flip=90'])
video0 = videoSource('v4l2:///dev/video0', ['-input-width=640', '–input-height=480', '-input-codec=mjpeg', ])
video1 = videoSource('v4l2:///dev/video2', ['-input-width=640', '–input-height=480', '-input-codec=mjpeg', ])

[dusty-nv]

Check the --input-flip option, I believe i added it recently for v4l2. Might be in the dev branch
