rviz和tf树报错修改

 跟着这个博主进行多机器人仿真，一直出错，有点崩溃了

ROS仿真笔记之——基于gazebo的ROS多机器人仿真_gwpscut的博客-CSDN博客 

TF_REPEATED_DATA warnings - ROS Answers: Open Source Q&A Forum 

尝试1：没有用

false
false

尝试2：虽然机器人模型不报错了，但是warning仍旧报错，尝试查看tf树

 尝试3：

rosrun rqt_tf_tree rqt_tf_tree

 报错

安装pyqt5

pip install PyQt5 -i https://pypi.douban.com/simple

继续运行rosrun rqt_tf_tree rqt_tf_tree，报错

报错 ，但是出现tf树了

尝试卸载PyQt5

pip uninstall PyQt5

pip list 
pip uninstall PyQt5-Qt5   5.15.2

  Successfully uninstalled PyQt5-Qt5-5.15.2
WARNING: Skipping 5.15.2 as it is not installed.

再次pip list没有PyQt5了，虽然有一个 PyQt5-sip  12.11.0，暂时不管，重新安装5.10

还是先卸载sip吧，估计有问题

pip uninstall PyQt5-sip                     12.11.0

 运行tf树还是出现这个蓝色字体，tf树看起来问题很大的样子
