ValueError: too many values to unpack (expected 2)

I use the train.json like:
{ "id": "1", "text": "俄罗斯海军总司令部对外表示，俄罗斯和印度已经签署海豹号核潜艇验收交付书。 按照海军总司令部代表的意思，目前海豹号核潜艇所有的试验已经成功完成，新年之后印度艇员将登舰训练，明年1月下旬潜艇将驶往印度东部海军基地。 海豹号属于俄罗斯第三代潜艇，于1991年在阿穆尔造船厂开工建造，但上世纪90年代中期由于资金不足导致建造中止，在获得印度方面的投资后才得以恢复。2008年11月该潜艇在日本海进行工厂航行试验时，由于氟利昂泄漏造成20人牺牲、21人受伤的事故。事故后，海豹号潜艇进行了维修，更换了灭火设备，并成功完成试验后于去年底加入俄罗斯海军服役。海豹号潜艇排水量12770吨、最大航速30节、最大潜深600米、自持力100天，装备有巡航导弹、鱼雷，人员编制80余人。 目前印度海军组成中还没有核潜艇，本国第一艘潜艇于2009年开工建造，正准备进行航行试验。 印度向俄罗斯租借潜艇一事引起巴基斯坦的恐慌，巴基斯坦外事部官方代表表示将密切关注事态的发展，并将自己国家的核武器提高到战备状态。 ", "event_list": [ { "event_type": "Experiment", "trigger": { "text": "试验", "offset": [ 199, 201 ] }, "arguments": [ { "role": "Subject", "text": "俄罗斯海军总司令部", "offset": [ 0, 9 ] }, { "role": "Equipment", "text": "海豹号核潜艇", "offset": [ 53, 59 ] }, { "role": "Date", "text": "2008年11月", "offset": [ 178, 186 ] },

and i write the Eventtype in event_type.py，like:
`
class InjureEvent(BaseEvent):
NAME = 'Injure'
FIELDS = [
'Subject',
'Quantity',
'Location',
'Date',
]

def __init__(self, recguid=None):
    # super(EquityPledgeEvent, self).__init__(
    super().__init__(
        InjureEvent.FIELDS, event_name=InjureEvent.NAME, recguid=recguid
    )
    self.set_key_fields([
        'Subject',
        'Quantity',
        'Location',
    ])

def is_good_candidate(self, min_match_count=8):
    key_flag = self.is_key_complete()
    if key_flag:
        if self.nonempty_count >= min_match_count:
            return True
    return False

common_fields = ['Subject', 'Date', 'Location']

event_type2event_class = {
ExperimentEvent.NAME: ExperimentEvent,
ManoeuvreEvent.NAME: ManoeuvreEvent,
DeployEvent.NAME: DeployEvent,
SupportEvent.NAME: SupportEvent,

}

event_type_fields_list = [
(ExperimentEvent.NAME, ExperimentEvent.FIELDS),
(ManoeuvreEvent.NAME, ManoeuvreEvent.FIELDS),
(DeployEvent.NAME, DeployEvent.FIELDS),
(SupportEvent.NAME, SupportEvent.FIELDS),
(AccidentEvent.NAME, AccidentEvent.FIELDS),

]

What went wrong, please? It's been bothering me for a long time. I hope to get a reply
