Trying to run periodic commit results in an error about cycli HOT 2 OPEN

These queries are run like this:

    def cypher(self, statement):
        error = False
        headers = []
        rows = []

        start = datetime.now()
        tx = self.graph.begin()

        try:
            result = tx.run(statement, self.parameters)
            headers = list(result.keys())
            rows = [[x[header] for header in headers] for x in result]
            tx.commit()
        except KeyboardInterrupt:
            tx.rollback()
            error = ""
        except Exception as e:
            error = e

Maybe @nigelsmall has an idea?

from cycli.

When using "USING PERIODIC COMMIT 250" with "LOAD CSV" in cycli i get the following error; "Executing queries that use periodic commit in an open transaction is not possible. [Neo.ClientError.Statement.SemanticError]"
Running the exact same query in cypher-shell connected to the same Neo4j Node (3.3.1) runs without any problems.

The query:

`USING PERIODIC COMMIT 250

LOAD CSV WITH HEADERS FROM "http://nginx/country.csv" AS countryLine FIELDTERMINATOR ','

MERGE (c:Country { fao: countryLine.fao,
numeric3: countryLine.numeric3,
alpha3: countryLine.alpha3,
alpha2: countryLine.alpha2,
name: countryLine.name })
WITH c
SET c :Geography;`

Tested on :
Cycli version: 0.7.6
Neo4j version: 3.3.1
Python 3.6.3 in python:alpine docker container

from cycli.
