I don't see any actual error messages there, is this the terminal you are running the bag in or the slam system?

When I run roslaunch bruce_slam.launch, rviz starts normally, and this terminal does not report an error. However, when I opened a new terminal to run osbag play sample_data.bag, the terminal running roslaunch bruce_slam.launch reported the above error.

I don't know if it's because of pcl.cpp and cfar.cpp in the directory of 'bruce_slam/src/bruce_slam/cpp/'. If these two files don't successfully create python interfaces through pybind11, will the above problems occur? I look forward to your reply very much and thank you very much.

Dear author, when I was debugging code in vscode, I ran slam.launch and the data set of a single robot. However, when feature extraction is carried out in the whole slam process, the feature_extraction.py file will crash in line 242nd code points = PCL. Downsample (points, self. resolution). What is the reason? I built it completely according to your project. Is it the pcl library version?

hello，have you solve this problem？ I meet the same problem，but i dont know how to solve it

[qimg412]

hello, I found that feature_extraction.py could not extract feature and the feature topic can not publish sucessfully, there was no data return
