imu_filter_madgwick is not in the package!

[Karishinamdar]

I am trying to use rtabmap with realsense-D435i. When I am running following command, it's showing me error that couldn't find the imu_filter_madgwick file. It's supposed to be in rtabmap, but when I am checking manually then also I couldn't find it. How can I achieve this file?

rosrun imu_filter_madgwick imu_filter_node
_use_mag:=false
_publish_tf:=false
_world_frame:="enu"
/imu/data_raw:=/camera/imu
/imu/data:=/rtabmap/imu
