No Image Received/No Map Received in RVIZ, Please Help!

[lbbbbl]

Hello, when i roslaunched DS_SLAM_TUM.launch, there's no error reported and RVIZ was switched on successfully, but there were no results. I found some similar problems in the comments but i am still confused. i thought i added components by topic and sitll i got no image received or map received. Did i set the wrong dataset path? Could u please tell me the correct way to edit the launch.txt? I m a little confused by the sentence "Change PATH_TO_SEQUENCE and PATH_TO_SEQUENCE/associate.txt in the DS_SLAM_TUM.launch to the sequence directory that you download before", i looked it up and found that i need a script named associate.py, i did what i did when running TUM dataset in orbslam2. Please do reply me. THX!

sorry for the late reply, can you snapshot your running results? It seems RVIZ works well and topic is set up, but no data published? Maybe you can print some info in the code to see where it stops? PATH mostly could be wrong, causing no file is loaded successfully, try to use the absolute path first, and then switch to the relative path. just check if it works.
