Hi @anirudhyadav1001!

The error happens because your file doesn't have "execute permissions".

In order to solve that, you can give "execute permissions" using the command below:

chmod +x visualize_velocity_profile.py

Now, if you call rosrun teb_local_planner_tutorials visualize_velocity_profile.py again it should work.

If you prefer, I've created a video where we give and remove "execute permissions" to confirm that this is the reason behind the error.

Cheers.
