Some Problems when launching single_tb3_house.launch

[yunlongguo2000]

Hello, when I launching single_tb3_house.launch, there is an error with

while processing /home/leon/catkin_explore/src/multi-robot-rrt-exploration-melodic/ros_multitb3/launch/includes/move_base2.launch: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'/home/leon/catkin_explore/src/multi-robot-rrt-exploration-melodic/ros_multitb3/launch/includes/move_base2.launch'

I change move_base2.launch to move_base.launch
then the Gazobo has died and no robot and scene in the Rviz at all !

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >' what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument

Could you please tell me where is wrong? Thanks a lot !
