I am following this tutorial [link text](http://wiki.ros.org/differential_drive)
After installing the Differential_drive package from this link [link text](https://github.com/jfstepha/differential-drive) with catkin_make,
I tried to run it with the following command :
` rosrun differential_drive twist_to_motors.py `
(Autocomplete doesn't work for the twist_to_motors.py part!)
It gives the following error !!:
```
[rosrun] Couldn't find executable named twist_to_motors.py below /home/aissa/catkin_ws/src/differential-drive
[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/aissa/catkin_ws/src/differential-drive/scripts/twist_to_motors.py
```
I am using ubuntu MATE 16.04 with ROS kinetic both installed on a raspberry pi 3.
I also had the same issue in the ubuntu 14.04 with ros indigo installed !
Please do you guys have an Idea as to what causes this problem ?
