All functions are running normally, except for the lack of Plugins and the inability of rviz to display the coordinate system.

Hi, thank everyone who would give any advice on the following problems.
I follow the guidelines to install and to configure. And everything seems fine, since when I roslaunch the file adapted from "ur5e_realsense_calibration.launch", every interface appear normally, which taking samples, automatic motion planning and executing, and computing can all be done normally. However, there are still two problems:
First, the interface of "rqt_easy_handeyecalibration_Hand-eye Calibration - rqt" has no plugins. Consequently, I have no idea how to calibrate without image viewer. Another problem is the interface of rviz cannot display the tf frame. Thus, I cannot tell whether the calibration is correct.
The image shows as followed:
