我正在尝试将一个较大的csv文件（ 1458644行）加载到neo4j中，但是我仍然遇到此错误：
Neo.TransientError.General.OutOfMemoryError: There is not enough memory to perform the current task. Please try increasing 'dbms.memory.heap.max_size' in the neo4j configuration (normally in 'conf/neo4j.conf' or, if you you are using Neo4j Desktop, found through the user interface) or if you are running an embedded installation increase the heap by using '-Xmx' command line flag, and then restart the database.
即使我将dbms.memory.heap.max_size=1024m更改为m = megbite，也会再次发生相同的错误！
注意：的csv大小为 195.888 KB
这是我的代码：
load csv with headers from "file:///train.csv" as line
create(pl:pickup_location{latitude:toFloat(line.pickup_latitude),longitude:toFloat(line.pickup_longitude)}),(pt:pickup_time{pickup:line.pickup_datetime}),(dl:dropoff_location{latitude:toFloat(line.dropoff_latitude),longitude:toFloat(line.dropoff_longitude)}),(dt:dropoff_time{dropoff:line.dropoff_datetime})
create (pl)-[:TLR]->(pt),(dl)-[:TLR]->(dt),(pl)-[:Trip]->(dl);
我该怎么办？

您应使用periodic commits批量处理CSV数据。例如，这将一次处理10,000行（默认批处理大小为1000）：
USING PERIOD COMMIT 10000
LOAD CSV WITH HEADERS FROM "file:///train.csv" as line
CREATE (pl:pickup_location{latitude:toFloat(line.pickup_latitude),longitude:toFloat(line.pickup_longitude)}),(pt:pickup_time{pickup:line.pickup_datetime}),(dl:dropoff_location{latitude:toFloat(line.dropoff_latitude),longitude:toFloat(line.dropoff_longitude)}),(dt:dropoff_time{dropoff:line.dropoff_datetime})
CREATE (pl)-[:TLR]->(pt),(dl)-[:TLR]->(dt),(pl)-[:Trip]->(dl);
