Did you forget to define or remap ‘/robot_description_semantic’?

git clone 了windowx-arm的仓库，没有任何改动，运行roslaunch widowx_arm_description widowx_rviz.launch命令，虽然也现实了rviz的页面，但是无法对rviz的显示的机械臂进行交互。提示错误

[ERROR] [1594040615.495994665]: Robot semantic description not found. Did you forget to define or remap ‘/robot_description_semantic’?
