140 만 개 이상의 노드와 1 억 6 천만 개 이상의 관계가있는 거대한 그래프 데이터베이스를 만들고 있습니다. 내 코드는 다음과 같습니다TypeError : JSON을 직렬화 할 수 없습니다. Py2neo Batch submit
from py2neo import neo4j
# first we create all the nodes
batch = neo4j.WriteBatch(graph_db)
nodedata = []
for index, i in enumerate(words): # words is predefined
batch.create({"term":i})
if index%5000 == 0: #so as not to exceed the batch restrictions
results = batch.submit()
for x in results:
nodedata.append(x)
batch = neo4j.WriteBatch(graph_db)
results = batch.submit()
for x in results:
nodedata.append(x)
#nodedata contains all the node instances now
#time to create relationships
batch = neo4j.WriteBatch(graph_db)
for iindex, i in enumerate(weightdata): #weightdata is predefined
batch.create((nodedata[iindex], "rel", nodedata[-iindex], {"weight": i})) #there is a different way how I decide the indexes of nodedata, but just as an example I put iindex and -iindex
if iindex%5000 == 0: #again batch constraints
batch.submit() #this is the line that shows error
batch = neo4j.WriteBatch(graph_db)
batch.submit()
