Answer

I will never be able to launch node yaml_to_camera_info.py & point_to_tf.py, because they are not built from source but just files I put in the directory /opt/ros/kinetic/share/rtabmap_ros/scripts/ . I install rtabmap by command sudo apt install.

Solution

$ source /opt/ros/kinetic/setup.bash
$ source ~/catkin_ws/devel/setup.bash

IF after sourcing .bash, the same errors still exist, it's time to rebuild rtabmap with a patch related to the ROS package VINS-Fusion.

First of all, clone the repository from GitHub. (Assume you have installed the prerequisites.)

$ cd ~/catkin_ws/src
$ git clone https://github.com/HKUST-Aerial-Robotics/VINS-Fusion.git

Then install this patch. To do this, you download, extract then put the patch in the directory of VINS-Fusion. (Maybe a ladder to some you know well will be use to check the patch and download it).

$ cd /home/william/catkin_ws/src/VINS-Fusion
$ git apply vins-fusion_e72b5f7.patch
$ cd ~/catkin_ws
$ catkin_make

Then rebuild rtabmap successfully. Some difference seems like this:
