I started using the robot for simple tasks but when I tried to program it with Python it got complicated. I used UniversalRobots/RTDE\_Python\_Client\_Library and at first it worked without any problem but out of nowhere it stopped working and gave me the error that the RTDE library could not be found. I tried to download it again because I assumed I had changed something but it gave me the same error.

You probably need to run the command in the example directory.  
You can run follow command:  
“cd examples && python3 example\_control\_loop.py”

“ur\_rtde” appears but I don’t see one that only has RTDE
