I am trying to compute a page rank with the code below be I keep getting the error:
message: Type mismatch: expected String but was Map
result=gds.run_cypher('''
CALL gds.pageRank.stream({
nodeQuery:'MATCH (d:Doc) WHERE d.id IN $isletter OR ((d) -[]- (n)
where n.id in $isletter)
RETURN DISTINCT id(d) AS id',
relationshipQuery: 'MATCH (d:Doc)-[r:r1|r2|r3|r4|r5|r6]-(n:Doc)
WHERE (d) IN $isletter
RETURN id(d) as source, id(n) as target,
r.weight_r1 as weight, r.weight_r2 as weight,
r.weight_r3 as weight, r.Weight_r4 as weight'
})
YIELD nodeId, score
return nodeId, score
ORDER BY score DESC''',params={'isletter': isletter})
Am I using the wrong syntax?
I previously wanted to create a projection first but that did not work as well. Here is how I did it:
pr, results = gds.graph.project(
'myPRGraph',
'''MATCH (d:Doc) WHERE d.id IN $isletter OR ((d) -[]- (n)
where n.id in $isletter)
RETURN DISTINCT d.id AS id''',
'''MATCH (d:Document)-[r:r1|r2|r3|r4|r5|r6]-(n:Doc)
WHERE (d) IN $isletter
RETURN d.id as source, n.id as target, r.weight_r1 as
weight,r.weight_r2 as weight,r.weight_r3 as
weight,r.weight_r4 as weight
''',
{'parameters':{'isletter': isletter}}
)
And got the error below:
TypeError: __call__() takes 4 positional arguments but 5 were given
Thanks in advance for your help.
