Bug report

Required Info:

• Operating System:
  • Ubuntu 20.04 (Focal)
• Installation type:
  • Upstream binary packages from http://packages.ros.org/ros2/ubuntu
• Version or commit hash:
  • ROS2 Galactic (stable) (also checked with ROS2 Foxy and ROS2 Rolling)
• DDS implementation:
  • Cyclone DDS
• Client library (if applicable):
  • tf2-geometry-msgs

Steps to reproduce issue

1. Install ros-galactic-tf2-geometry-msgs

   apt install ros-galactic-tf2-geometry-msgs`
   

2. Use it in Python:

   from tf2_geometry_msgs import do_transform_vector3
   

3. Run/launch the package

Expected behavior

• I expect tf2_geometry_msgs to be successfully imported.

Actual behavior

Running it gives the following error:

from tf2_geometry_msgs import do_transform_vector3
[behaviour_muxer-6] ModuleNotFoundError: No module named 'tf2_geometry_msgs'

Additional information

• The ros-galactic-tf2-geometry-msgs package does not install tf2_geometry_msgs.py.
• Searching for the file in /opt/ros/galactic does not return any results.
• I don't seem to find other relevant dependent packages that would install it.

In short, we need to merge and release https://github.com/ros2/geometry2/pull/532 and https://github.com/ros2/geometry2/pull/533 for this to work.

@clalancette Do you have a timeline for the release of these changes for Galactic and Foxy now that they have been merged?
