ImportError: cannot import name 'RoundTripDumper' with image

[vortex852456]

I tried the image but it doesn't work. See following history (shell from host-system):

root@localhost: cat docker-compose.yml | docker run -i funkwerk/compose_format
Traceback (most recent call last):
  File "/bin/compose_format", line 2, in <module>
    from compose_format import ComposeFormat
  File "/usr/lib/python3.5/site-packages/compose_format/__init__.py", line 1, in <module>
    from ruamel.yaml import RoundTripDumper, RoundTripLoader, dump, load
ImportError: cannot import name 'RoundTripDumper'
root@localhost:/var/docker/source/main# docker --version
