  my python code listed as following:

importdatetimeimportcsvimportclrclr.AddReference('CyberStone.Atp.Storage')fromCyberStone.Atp.Storage.QueryimportQueryConditionfromCyberStone.Atp.Modules.Analysis.ModelsimportSearchResModelfromSystem.Collections.GenericimportListfromSystemimportString,DateTime#define query conditioncondition=QueryCondition()condition.QueryValueVariables=List[String]()condition.QueryValueVariables.Add('Decoder/projectValue')condition.RowMax=100condition.StartTime=DateTime(2018,8,2)condition.EndTime=DateTime(2018,8,3)#start query databaseresult=dataAnalysis.GetSearchDataSet(condition)print(result.Count)

when I execute PythonEngine.Shutdown(), there is exception. do you know how to resolve it?
