Looking for a bag file of stereo images with loop closures Hi, I'm using ROS melodic. I'm running Ubuntu 18.04 on i7 ,

I have a package named node_exemple containing an msg folder containing these files

ViewTemplate.msg To run a python file depending on this message I used :

from node example.msg  import ViewTemplate

But I get this error :

from node_example.msg import ViewTemplate   
ImportError: No module named node_example.msg

The CMakeLists.txt is here :

Thank you. It works fine.

Hi,

I'm using ROS melodic with kitti bag file. I'm running Ubuntu 18.04 on i7 , with kernel 5.3.0-42-generic. I get the odometry of a Kitti bag file with viso2_ros. I want to predict the poses of the robot. To compute the next pose I should compute the quaternion of the robot. How can I compute it from angular velocity?

Thanks
