Description of the bug

I followed the installation from source tutorial: https://github.com/open-rmf/rmf#building-from-sources and the colcon build phase crashed on the package rmf_api_msgs with the message No module named 'datamodel_code_generator'. I fixed it with pip install datamodel_code_generator.
