When trying to load an odml file version 1.0 with odml version 1.4.2 the resulting error message states

odml.tools.parser_utils.InvalidVersionException: Cannot parse odML document with format version '1'. 
	Use the 'tools.VersionConverter' to import previous odML formats.

However, the version converter can not be used as described above, but needs to be explicitely imported from the submodule:

from odml.tools.version_converter import VersionConverter

Probably the VersionConverter should be linked in the odml.tools.__init__.py?
