Can't run vision_to_mavros

[maponarooo]

I don't know much about ROS, so I would like to inquire. The following error occurs. Please let me know how to fix it.

~$ roslaunch vision_to_mavros t265_tf_to_mavros.launch RLException: [t265_tf_to_mavros.launch] is neither a launch file in package [vision_to_mavros] nor is [vision_to_mavros] a launch file name The traceback for the exception was written to the log file

Hi @maponarooo , you may need to source the catkin workspace before you can launch the node:

source path_to_your/catkin_ws/devel/setup.bash
