Following https://github.com/nasa-jpl/osr-rover-code/blob/foxy-devel/setup/rpi.md in section:
6 Testing serial comm with the Roboclaw motors controllers
Run the roboclawtest.py script with all of the motor addresses:

ubuntu@AUDACITY:~$ cd ~/osr_ws/src/osr-rover-code/scripts
-bash: cd: /home/ubuntu/osr_ws/src/osr-rover-code/scripts: No such file or directory
ubuntu@AUDACITY:~$ sudo find / -name roboclawtest.py
/home/ubuntu/osr_ws/osr-rover-code/scripts/roboclawtest.py
ubuntu@AUDACITY:~$ cd osr_ws/osr-rover-code/scripts/
ubuntu@AUDACITY:~/osr_ws/osr-rover-code/scripts$ python roboclawtest.py 128
Command 'python' not found, did you mean:
  command 'python3' from deb python3

ubuntu@AUDACITY:~/osr_ws/osr-rover-code/scripts$ python3 roboclawtest.py 128

As mentioned on Slack,

-bash: cd: /home/ubuntu/osr_ws/src/osr-rover-code/scripts: No such file or directory

means you made a mistake and you cloned the repository to the wrong folder.

This is also why the above issue with ModuleNotFoundError happens. We add that directory to the python path directly, and in your case it can't find it because it's wrong.
