Kernel Restarting when activating Compute detections on single camera image in JupyterLab

Under the heading in the Jupyter Notebook - Object Following - Live Demo > Compute detections on single camera image with the cell below:

from jetbot import ObjectDetector

model = ObjectDetector(‘ssd_mobilenet_v2_coco.engine’)

When I hit the run button, I get the message: “The kernel for Notebooks/object_following/live_demo.ipynb appears to have died. It will restart automatically.” The execution count number never appears.

I have: 1) rebooted both the PC and the Jetson Nano, and 2) tried the other ssd mobilenet v2, but the same message occurs. I’m only using the code that came with the JupyterLab Notebook.

Any help is appreciated,

Hi myrobotfl,

Thanks for reaching out!

Do you mind sharing the output of

journalctl -u jetbot_jupyter

My guess is that there is a mismatch between the SD card image you’re using and the object detector’s compiled engine.
