Issues downloading and running docker for "Getting Started with AI" DLI course

If you have flashed the JetBot SD card image, then you shouldn’t need to use the docker container.

Can you try running the Jupyter notebook outside of container, as shown in step #5 of this page?

https://jetbot.org/master/software_setup/sd_card.html

It seems there error you are getting above is i2c “Remote I/O error”, so I wonder if perhaps there is some connection issue, or if multiple notebooks were running. You can get ahold of the JetBot guys by filing an issue on their GitHub, they will know better than I:

Chitoku and dusty_nv,

Thank you, Chitoku, for clairifying hardware-software compatibility. The following will not run on the JetBot: rosrun JetBot_ros JetBot_motors.py
Am I running rosrun at the wrong prompt level?

So, I started over, as follows:
Hardware: SparkFun JetBot AI Kit v2.1 (kit-16417)
64 GB Sandisc flashed with: jetson-nano-4gb-jp441-sd-card-image
Process Guide followed: github.com/dusty-nv/jetbot_ros README.md - [ROS nodes and Gazebo model for NVIDIA JetBot with Jetson Nano]

Each step ran through “Testing the JetBot” at rescore

SUMMARY

Hi @vludwig, have you been able to run the normal JetBot software from jetbot.org (either the JetBot containers or SD card image) to confirm that your JetBot is working first, before attempting the ROS nodes?

Regarding the rosrun command, I believe your log got truncated when posting it to the forums, as I do not find an error.

Thanks so much!
