Query the full graph as subgraph about kglab

[csaparna]

I did encounter the same error while trying to use an rdf file in ttl format to read in as ig_graph. However, It was successful in creating a networkx graph. I used a similar query as above:

query = """
SELECT ?subject ?object
WHERE {
    ?subject ?p ?object .
}
"""

to query for the entire graph.
