No visual feedback from flyingroom.bag in rviz

[geothan]

Hi, i tried to run the flyingroom.bag, but rviz shows nothing.

i tried :
roslaunch dvs_tracking flyingroom.launch auto_trigger:=true
rosbag play -r 0.7 /home/george/event_datasets/evo/evo_flyingroom.bag

The output of first terminal returns multiple warnings:

[ WARN] [1641575533.511405484]: TF_REPEATED_DATA ignoring data with redundant timestamp for frame world at time 1621507165,016965 according to authority unknown_publisher

Hi, I encountered the same problem, have you solved it now?
I tried the same command as you, and rviz still showed no image.
The first terminal displays warnings and Errors, for example：

[ WARN] [1649228586.448471942]: Cannot find value for parameter: set_initial_attitude_from_gravity, assigning default: 1
[ WARN] [1649229755.354212826]: Not enough matched features.
[ERROR] [1649229756.759911296]: SparseImgAlign: no features to track!
