it shows:

The ros setup may not have been completed correctly.
Have you tried source ./devel/setup.bash in the catkin_ws directory?

thanks for your reply, I did the source ./devel/setup.bash otherwise I can not run the whole code. The second question is the code always breaks in half way, I play the rosbag, the dataset-corridor1_512_16.bag, and it always breaks at about 100s, shows exit code -11,and no meaningful information, the same thing happened when I run the official ros version, the code also breaks at about 100s. Both questions confused me a lot.
