Hi all,
I’m facing an issue while running the basic_motion.pynb file on Jupyter Notebook. Specifically, the error occurs when I try to execute the following code cell:
robot = Robot()
As soon as I run this cell, an error pops up. I’ve attached a screenshot of the error for reference.
After checking the error path, I noticed that the directory mentioned in the error message (/usr/local/lib/python3.6/dist-packages/jetbot-0.4.1-py3.6.egg/jetbot/robot.py) does not exist on my system. When navigating to the path, the directory appears to be empty.
error:

I’ve attempted some initial troubleshooting but haven’t been able to resolve the issue. Has anyone encountered this problem before or can provide guidance on how to resolve it?
Any help would be greatly appreciated!
