I'm using py2neo 2.x on Neo4j 3.0.3. Sometimes creating index from Python
script fails. If I run the same Python line manually from Python 3 IDLE, it
almost always succeeds. Any idea? Is this the correct way to create index?
My Python 3 code has these two lines:
if 'addr' not in graph.schema.get_indexes('host'):
graph.cypher.execute("CREATE INDEX ON :host(addr)")
and I got these error messages:
graph.cypher.execute("CREATE INDEX ON :host(addr)")
File
"/usr/local/python/lib/python3.4/site-packages/py2neo/cypher/core.py", line
136, in execute
results = tx.commit()
File
"/usr/local/python/lib/python3.4/site-packages/py2neo/cypher/core.py", line
333, in commit
return self.post(self.__commit or self.__begin_commit)
File
"/usr/local/python/lib/python3.4/site-packages/py2neo/cypher/core.py", line
288, in post
raise self.error_class.hydrate(error)
py2neo.cypher.error.transaction.DeadlockDetected: LockClient[29] can't wait
on resource RWLock[SCHEMA(0), hash=1676963340] since => LockClient[29]

Thanks,
