when I try to launch the roslaunch rbkairos_sim_bringup rbkairos_complete.launch` file, it gives me this error.

According to another similar question raised by a user https://answers.ros.org/question/1220...

I tried this command rosrun xacro xacro.py /home/impaidk/catkin_ws/src/rbkairos_common/rbkairos_description/robots/versions/rbkairos_ur5_egh.urdf.xacro to check if there are any problem in the xacro but i get this result.

What is your question exactly?

From your description it appears you did not follow the regular procedure for building and using packages you cloned from repositories (such as #q252478).

The readme in RobotnikAutomation/rbkairos_sim (this one) seems to contain the correct instructions.

I actually wasn't sure if I had followed the regular procedure, so cloned the packages again and build it again according to the regular procedure. I still get the same error.

https://github.com/RobotnikAutomation... I want to run the bringup as mentioned on this page

If you've followed the readme from the RobotnikAutomation repository, I would suggest to ask them.
