Hi, I tried transforming roll, pitch, yaw angles to a quaternion in python following this tutorial (http://wiki.ros.org/tf2/Tutorials/Qua...). In subtopic 3 "Think in RPY then convert to quaternion" the import statement is from tf_conversions.transformations import quaternion_from_euler. When trying to run my node python said that it can't find the module tf_conversions.transformations. I tried many things and finally looked into the source code of the package. Turns out that the import has to be from tf.transformations import quaternion_from_euler, because the quaternion_from_eulerfunction is located in this file: https://github.com/ros/geometry/blob/....

I am not sure how to correct the tutorial page but maybe this help somebody to change it or at least get the import right. I was struggling with this for 2 straight hours thinking the tutorial was right...
