Can I trade-in my Jetson TX2 for a newer models of Developer Kits? I had tried with no success to use my device to follow some DLI classes and I ended up getting stuck and not able to make it work. So I was wondering if I can trade it in and get a newer module that meet the class requirement and be able to follow the DLI classes?

Thanks. Abolade B.

Trade-In? I don’t think that’s a good method.
Suggest to focus on the the issue you met.

Thanks. I have had this device for some time but never got its camera working to follow any of the AI course on DLI. I was wondering if there is a specific docker image that I can use for the dli AI fundamentals course that is compatible with this course? Here is where I always get stuck:

from jetcam.usb_camera import USBCamera
camera = USBCamera(width=224, height=224, capture_width=640, capture_height=480, capture_device=0)

I always get this error which I do not know how to get past it:
"---------------------------------------------------------------------------
RuntimeError Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/jetcam-0.0.0-py3.6.egg/jetcam/usb_camera.py in init(self, *args, **kwargs)
23 if not re:
—> 24 raise RuntimeError(‘Could not read image from camera.’)
25

RuntimeError: Could not read image from camera.

During handling of the above exception, another exception occurred:

RuntimeError Traceback (most recent call last)

/usr/local/lib/python3.6/dist-packages/jetcam-0.0.0-py3.6.egg/jetcam/usb_camera.py in init(self, *args, **kwargs)

—> 28 ‘Could not initialize camera. Please see error trace.’)

"

Any clues or support you can offer will be appreciated.

Hi,

Do you have a “USB” camera connected to TX2?
Please note that you will need a different configuration if you are using a CSI camera like raspberry pi.

Thanks.

Yes I do have the USB Camera. When I ran “ls /dev/video*” I got back /dev/video0 and /dev/video0 back.

Thank you all, I finally figured out where my mistake was. Now I can read images from the camera. Thank you.

Thanks for the update.
