AttributeError when running CLI with version 1.6.0

[jarkenau]

When I install Datumaro via with pip install datumaro[default] version 1.6.0 is used. I get the following error when using the CLI, for example datum --help produces:

Traceback (most recent call last):
  File "/home/docker/.local/bin/datum", line 5, in <module>
