When I tried to use randomwalk, it gave me the error: "Procedure Not Found: There is no procedure with the name algo.randomWalk.stream registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed."
Then I used the codes as follow to check the algorithms in the latest jar:
list = api_graph.run("CALL dbms.procedures() YIELD name, signature, description "
"WHERE name starts with 'algo' "
"RETURN name, signature, description").data()
for l in list:
print(l)
I can't find randomWalk in it, I think it's the reason why it gave me the error, but I really need to do randomwalk on the graph of Neo4j. What should I do? Please help me.
