2020-06-03 18:45:05 -0500 marked best answer 3D LIDAR SLAM in 2020

Hi,

I have been using RTABMAP for SLAM with a stereo_camera, and it is working very well. It seems well maitained by the activity on the github page.

Now I am looking to perform the same task with a 3D LIDAR, but I cannot find a package that seems to be maintained. I checked: BLAM (last update 2016) and SegMatch (last update 2017).

Does anyone has a suggestion of a package that I can use? I am using ROS Melodic , but I am willing to migrate to Noetic.

2020-06-03 18:44:48 -0500 marked best answer Python3 and python2 on package

Hi,

I have in my ROS package nodes that are supposed to be run with python2 and with python3. I wanto to maintain common code in shared libraries, a python2/3 lib and a python3 only lib. I read that I can keep my python packages on the /src folder and write a setup.py file so the packages would be installed and available to my nodes when a run catkin_make or catkin build.

The question is, how can I install both python3 and python2/3 packages in the same setup file? This could be done by catkin? If no, what would be the better way of organizing my code in this situation?
