Similar to https://answers.ros.org/question/1720... I got this warning from move_base:

When checking the the topic in question though, it was arriving at high frequency. I've solved the issue now, and will post my answer, and since it is different from the above, I think it is useful to capture it here.

The costmap is not used for localization anyways. So you don't need to worry about this.

relocation R_X86_64_PC32 against symbol `_Py_NotImplementedStruct' can not be used when making a shared object; recompil

We have a large facility I want to map in stages. I've already created a decent map of a large portion of the facility but need to add additional rooms/corridors. I am able to continue mapping by starting on the existing map in localization mode, going to where I want to extend the map, setting rtabmap to mapping mode, and then going into the unknown (as recommended for multi-session mapping). This works but after a little while the occupancy grid map published on /rtabmap/grid_map is replaced by a new map that only shows the newly explored area. I understand from reading in the rtabmap forum that this is expected, and that the old map may reappear on that topic when the robot is back in that old area and a loop closure is detected. But I still need the complete map for navigation.

Is there a way to ask rtabmap to publish the global, merged 2D map during localization mode? Alternatively, is there a way to export the merged 2D map? I figured out how to export each individual map using rtabmap-databaseViewer (select the right node in the graph view (this step wasn't obvious) > Regenerate optimized 2D map > Export optimized 2D map). So that's a starts, but these maps come without a yaml file containing the origin, so it's not clear how to align them for manual merging.

Are you aware of webviz and foxglove studio? Sounds like what you are planning to build is very similar.

thanks. Do you get the same error when you just run ros2 (without any arguments)?

what do you get when you type which ros2 and ls -la $(which ros2)

This isn't enough detail to help you. Please show the code you use and how you are calling it.

Well there is your problem. Like the Troubleshooting says, you have to be able to resolve all names listed by rosnode li

can you resolve cpr-mic09 from the client, i.e., what happens when you ping that from the client?

Have you already tried the steps described in the Troubleshooting comment below the gist?

Like many people I struggle with this myself several times, so I eventually created a gist for setting things up correct

typo: I think you meant packages.ros.org (not com)

Almost definitely an issue with their docker image. It's a wild guess, but it seems quite plausible that this is related

The name of that package is different from its folder name, as can be seen using rospack: > rospack list | grep aws

yes, of course. But in order to tell you how we'd need to see your code and potentially launch files.

Actually, you are probably just missing: ros-melodic-nav-core-adapter - This package contains adapters for using 'nav_co

You probably want to install the entire nav_core2 package: ros-melodic-nav-core2.

Most likely you just don't have that planner installed that you are specifying in your config. Make sure they are by run
