Using ROS2 Bouncy, I cannot import tf2_ros in my python scripts. I can import tf2_msgs, and I can use TF2 just fine in C++ executables, for example using #include <tf2_ros/transform_listener.h>. What do I need to do to access the same functionality in python? How do I fix this?

Edit: I have confirmed the same issue exists on another computer with a clean install of Bouncy.

Edit 2: It seems that tf2_ros and some related modules are not being built, according to this pull request.

Edit 3: I have opened an issue here.

@beck. Do you know if tf2_ros (python) works in "Crystal Clemmys"?

It does not. I will leave this question as unanswered until it is fixed.

The Functionality is finally included in Eloquent, but it is not backward compatible to Dashing.
