Hi, I connected to the real vehicle and launched rtabamp, but it shows the following error:

Dear Mattieu, I also installed velodyne_master that has the patch, from the source, and did catkin_make as well. but again when I launch rtbamp,I face the same error. Would you please support to fix this issue? thanks

hi everyone, my issue, has not fixed yet. I have downloaded also velodyne_master, and then did catkin_make in my workspace. then run rtabmap, but again i have this error yet:

[FATAL] (2021-05-27 16:14:50.261) MsgConversion.cpp:2198::convertScan3dMsg() Condition (scan3dMsg.data.size() == scan3dMsg.row_step*scan3dMsg.height) not met! [data=590964 row_step=0 height=1]

would you please support me to resolve this issue?. Thanks

try to debug why the velodyne topic has row_step=0, if the patch referred by the answered didn't work on your side for some reasons.
