When run:
$ python -m unittest cyborg.tests.unit.accelerator.drivers.modules.test_generic
It will report the follow error:

from cyborg.accelerator.drivers.generic_driver import GenericDriver as generic
File "cyborg/accelerator/drivers/generic_driver.py", line 24, in <module>

existing.add_item(cls)
AttributeError: '_ModuleMarker' object has no attribute 'add_item'
That's because:
_ModuleMarker will add the module name and class name in to same contents dict.
_MultipleClassMarker refers to multiple classes of the same name within _decl_class_registry.
It has add_item attribute.
_ModuleMarker refers to a module name within _decl_class_registry.
It does not have add_item attribute.
So the class name should be different with module name.
