[rospack] Error: package 'tag_detector_ros' not found


well it would seem that 'tag_detector_ros' is just not a package in your workspace.

[rospack] Error: package 'tag_detector_ros' not found


well it would seem that 'tag_detector_ros' is just not a package in your workspace.workspace, and looking at the output of the find command, it would appear to actually be a directory, containing other ROS pkgs (ie: aruco_ros, apriltags2_ros, visp_auto_tracker, etc).

roslaunch can only launch launchfiles from actual ROS packages, or if you don't have a package, you can provide it with an absolute path to a launch file.

In your case using the latter option would probably be possible. Something like this should work (provided there are no problems with the launch file itself):

roslaunch /path/to/your/catkin_ws/src/tag_detector_ros/launch/allTags.launch
