from ontolearn.knowledge_base import KnowledgeBase
from owlapy.owl_individual import OWLNamedIndividual
# (1) Initialize Triplestore
kb = KnowledgeBase(path="KGs/Family/family.nt")
print(kb.ontology) # Ontology(IRI('http://www.benchmark.org/family#',''), True)
print(kb.reasoner) # <owlapy.owl_reasoner.FastInstanceCheckerReasoner object at 0x7fde3074aca0>
for i in kb.reasoner.types(OWLNamedIndividual("http://example.com/father#stefan")):
    print(i)

throws AttributeError: 'NoneType' object has no attribute 'INDIRECT_is_a' because self._world[ind.str] returns None.
