How can I reset the systems (reset a python script)?

I accidentally updated something. When I ran the python script, it gives “ImportError: No module named robot_control_class”

Hi @leozengzheng,

welcome to our community.

Did you manage to solve the import error?

If not, you could just copy the original content from the previous notebooks.

If this isn’t an option, could you paste here the content of your script so that we can check why it is failing?
