Hi Phreddog24,
Thanks for reaching out!
This may be the result of with a mismatch between the version of PyTorch and Torchvision. For using JetBot, the latest validated instructions are located here
https://jetbot.org/v0.4.3/software_setup/sd_card.html
If you’re interested in doing a custom setup and not using these docker containers, I would recommend following this post for installing PyTorch on Jetson
Please let me know if this helps, or if you run into any questions / issues.
Best,
John
