[detect-1]killing on exit

[PauloMendes33]

RLException: Unable to launch [detect-1]. If it is a script, you may be missing a '#!' declaration at the top. The traceback for the exception was written to the log file

When I try to run roslaunch yolov5_ros yolov5.launch it returns this error message. What should I do?

Hi Paulo,

I will look into the issue but for now I am not sure where the error comes from. Is YOLOv5 working on your machine? Could you try run it independently without the ROS wrapper?

[PauloMendes33]

Yes. Yolov5 is running smoothly. I tried it a lot of times.

[PauloMendes33]

I am using Ubuntu 18.04 and ROS melodic.

Hi Paulo, Did you find any solution? I have the same problem, too.

[abhishekt711]

Yes in the first line of script change to this #! /usr/bin/env python3

[HooradAboo]

Thanks for your response. I did this, too. It does not work for me.

[nhatleminh1997]

@HooradAboo @PauloMendes33 hi sorry I haven't had time to work with Ubuntu 18.04 and ROS Melodic. Could you try to follow the instruction here http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment for Python 3 users in ROS Melodic and earlier? I just also added to the repo instruction the step to make the Python script executable in case you have not done it yet.

[HooradAboo]

Thank you so much. I compile it with "catkin_make" instead of "catkin build" and it works for me.
