loading local json files fails #607
Description
loading local OboGraph JSON files following examples from the notebooks or using local obograph JSON files generated by ROBOT consistently => empty graphs
eg.
from ontobio.ontol_factory import OntologyFactory
ont = OntologyFactory()
n = ont.create("./tests/resources/nucleus.json")
2021-12-01 22:16:19 [WARNING] [PID:90975 TID:4447808960] [sparql_ontol_utils.py:98 in `get_edges`] No edges for ./tests/resources/nucleus.json
2021-12-01 22:16:19 [ERROR] [PID:90975 TID:4447808960] [sparql_ontology.py:233 in `__init__`] Empty graph for './tests/resources/nucleus.json' - did you use the correct id?
# OTOH - Loading remote using OBO ontology ID works fine.
pato = ont.create('pato')
pato.search('morphology')
['PATO:0000051']
pato.parents('PATO:0000051')
['PATO:0001241']I've seen this with both PyPi install and the latest code from GitHub.
