**IndexError: string index out of range**

code is following:

main.py

# load Baidu LAC service
import paddlehub as hub
lac = hub.Module(name='lac')
slot_extractor = info_extractor(lac)
for i in range(len(xx)):
    slot_extractor.run_lac('text')
...

info_extract.py

class info_extractor:
    def __init__(self, lac, logger):
        self.lac = lac
    def run_lac(self, text):    #  text是一句话
        data = {'text':[text]}
        results = self.lac.lexical_analysis(data=data)  # IndexError: string index out of range
...

main.py 会调用多次info_extract.py，每隔一段时间就会报错IndexError: string index out of range，请各路大神帮忙看看，谢谢
