roslaunch error

[FrozenSmile]

Thanks for your great work！ My first compiling failed because of the same error in issue #10 and #15，I checked out 7e985e9 and succeed to compile but some errors still occurred when I roslaunch.

I just change the "bag file" to the path of rosbag.
I execute roslaunch kimera_semantics_ros kimera_semantics.launch play_bag:=true and the rosbag played properly but some errors ouccrred as this:

[ERROR] Failed to load nodelet [/cloudify] of type [depth_image_proc/point_cloud_xyzrgb] even after refreshing the cache.

[cloudify-4] process has died [pid 123603,exit code 255, cmd /opt/ros/kinetic/lib/nodelet load depth_image_proc/point_cloud_xyzrgb noodelet_manager -no-bond rgb/camera_info:=/tesse/left_cam/camera_info rgb/image_rect_color:=/tesse/segmentation/image_raw depth_registered/image_rect:=/teese/depth/image_raw depth...

Nothing but a moving line in my rviz. I put the error picture to show you.It looks like the same error in #10 and #13 , but I don't understand how they fixed it. By the way，I use the new rosbag you updated in the usage, so the answer in #13 didn't help me .

I guess it's the problem about node name or pkg name so I modify the launch file as the last merge, but the error still exists.

I'm a green hand in SLAM and lack for experience, please give me some suggestion to fix errors if you can, thank you.

Hi @FrozenSmile,

Thanks for the report! As noted in #15 , try:

sudo apt-get install ros-melodic-depth-image-proc

Change melodic for your ROS distribution (i.e. kinetic etc)

sudo apt-get install ros-melodic-depth-image-proc Thanks a lot for your answer ! It works immediately!
