Bayes_tutorials package missing from workspace


I am following the Kalman Filters course but I cannot run examples and tutorial code. In particular, when trying to launch

roslaunch bayes_tutorials simulated_robot.launch in exercise 2.12 (or any other for that matter) I get an error message because the bayes_tutorials package is missing.

Where should I find such package? The default catkin workspace does not have any package in it.

Did you skip any part of the notes? Usually such packages are copied or created at the beginning of the course.

I have indeed. I assumed the code in the first chapter of the course was related to such part only, and I forgot about it. The notes clearly state that the code is useful throughout the whole course.
