Keyboard_velmux_launch importing Arm error

[piratax007]

Hello,

I'm using Vicon as a motion capture system and I change the Crazyflie ID in the keyborad_velmux_launch.py file.

When I run

ros2 launch crazyflie_examples keyboard_velmux_launch.py

I get the error

[crazyflie_server.py-1] ImportError: cannot import name 'Arm' from 'crazyflie_interfaces.srv' (/home/fausto/ros2_ws/install/crazyflie_interfaces/local/lib/python3.10/dist-packages/crazyflie_interfaces/srv/__init__.py)

and the execution is blocked there.

Any idea about how to solve it?

Thanks a lot.

Did you try a clean build? Are there any errors during the build? The service is defined here: https://github.com/IMRCLab/crazyswarm2/blob/main/crazyflie_interfaces/srv/Arm.srv and seems to be somehow not get Python bindings in your case.

Thank you for your answer,

I update the installation of the Crazyswarm2 as in indicated here https://imrclab.github.io/crazyswarm2/installation.html and I have the following message at the end of the compilation

2 packages aborted: crazyflie crazyflie_py
