I have encountered some questions when I run the demo. #1

when I run the demo you provided, I encountered the following issues:

[ERROR] [1658393472.346670577]: PluginlibFactory: The plugin for class 'graph_rviz_plugin/Line graph' failed to load. Error: According to the loaded plugin descriptions the class graph_rviz_plugin/Line graph with base class type rviz::Panel does not exist. Declared types are rviz_plugin_tutorials/Teleop

I have tried some approaches to solve it, but they didn't work.

Thanks for your interest!

That's just an RVIZ configuration issue. Note that this is an RVIZ error that does not affect the SLAM system. I have pushed a new RVIZ config to clear your issue. If you can pull the most recent update to the repo and test that your issue is gone, I will close the issue.

If you were interested in using it, it's a line graph tool for RVIZ from this page https://gitlab.com/InstitutMaupertuis/graph_rviz_plugin

Thanks!

First of all, THANKS for your help!

I have solved the problem mentioned above successfully, but at the same time, new issue is coming out!

when I run this code in terminal roslaunch bruce_slam slam.launch everything is OK.

But when I run the following code in a new terminal rosbag play sample_data.bag

Errors are occured! [bruce/slam/feature_extraction-4] process has died [pid 9543, exit code -11, cmd /home/casia/sonarslam/src/sonar-SLAM/bruce_slam/scripts/feature_extraction_node.py __name:=feature_extraction __log:=/home/casia/.ros/log/e8a974dc-0965-11ed-a30d-73dbe08c713f/bruce-slam-feature_extraction-4.log].

Apologies for the delay on my end.

That error message looks incomplete, but I suspect you are having a python import issue. Did you install all the relevant python dependencies listed on the readme?

snowman-maker commented 2 years ago

Thanks for your reply.

I have checked all the dependencies needed today, and then I rebuilt the target, however, nothing changed...

jake3991 commented 2 years ago

Can you post the whole error message? The error you posted does not have a line number or actual python error

jake3991 commented 2 years ago

Any updates?

Closing due to inactivity, feel free to open a new issue if you are still having problems

I'm very sorry that I haven't replied to you for so long。 During this period, I'm still consolidating my knowledge of slam. I hope I can use the code you provide after a period of time. In short, thank you very much for your help。 If I have any questions, I will open a new issue!
