mavros.register_on_namespace_update(_setup_services)

[AldrichCabrera]

Hi.

I have a problem when run the command for arm the drone.

odroid@odroid:~/catkin_ws$ rosrun mavros mavsafety arm
Traceback (most recent call last):
File "/opt/ros/kinetic/lib/mavros/mavsafety", line 18, in
from mavros import command
File "/opt/ros/kinetic/lib/python2.7/dist-packages/mavros/command.py", line 51, in
mavros.register_on_namespace_update(_setup_services)
AttributeError: 'module' object has no attribute 'register_on_namespace_update'

Does anyone know how to solve this?

I have ROS kinetic on odroid, the version the mavros, mavros_msgs is 0.19.0. I try all the solutions that I find in the internet but nobody can solved it.

Have you tried to update python?

[AldrichCabrera]

I have Python 2.7.12 and another computer i have 2.7.6. I even installed the pkg with:
sudo apt-get install --reinstall python-catkin-pkg

but the error persists

[TSC21]

What's the ouput of rostopic echo -n1 /diagnostics and the ouput of your mavros_node?

[vooon]

Check content of /opt/ros/kinetic/lib/python2.7/dist-packages/mavros/__init__.py file. It should have function register_on_namespace_update().

[TSC21]

@AldrichCabrera that's the rostopic list. I meant the output of the terminal console when you launch the node. And also from rostopic echo -n1 /diagnostics. Use markdown formatting for that please.

@vooon hi i already checked the content and i definitely have what you tell me

[AldrichCabrera]

Solved only need install these pkg:
sudo apt-get install geographiclib-tools
sudo apt-get install python-geographiclib

Thanks for you help.

[TSC21]

That's a result of a bad source install then. Closing
