Hi, I have finished all the steps following the instructions and nothing goes wrong. But when I run

roslaunch semantic_SLAM ps_slam_with_snap_pose_bucket_det_lab_data.launch bagfile:=${HOME}/Downloads/entire_lab_3_rounds.bag show_rviz:=true  

I get errors like this and it stucks for a while.

then I get this. It seems that the visualization program doesn't go right.

Is there something I have missed? Thank you!

When it occurs

[pcl::OrganizedNeighbor::radiusSearch] Input dataset is not from a projective device!
Residual (MSE) 0.000614, using 1248 valid points

the program is still mapping , so I think the problem is not caused by 'pcl'.

I tried to run the launchfile seperately :

ROS_NAMESPACE=camera/color rosrun image_proc image_proc 
roslaunch semantic_SLAM shape.launch  
rosrun semantic_SLAM  semantic_graph_SLAM_node

But at the last step i got 'Segmentation fault :

add first landmark: 0
Segmentation fault (core dumped)

Do you have any idea about it? Thanks a lot !!!

Hello, when I run the sample code, I always encounter network interruptions or unknown errors at the last moment when downloading the dataset entire_lab_3_rounds.bag. Can you provide a new way to download the bag?

Hola, he conseguido que ambos paquetes en conjunto (semantic slam y bucket detector) funciones bien en una distro de ubuntu virgen con ROS melodic, sin embargo, cuando migro al pc donde trabajo habitualmente y que tiene ya instaladas dependencias anteriores y demás me encuentro con estos errores referentes a opencv: Imagino que se deben a incompatibilidades entre versiones de opencv, podrías confirmarme esto último? Sería posible trabajar con una versión de opencv diferente? Gracias, un saludo!
