[Question]: 使用Taskflow模块，进行信息抽取输出是空

[panghongwei17]

请提出你的问题

from pprint import pprint
from paddlenlp import Taskflow

schema = ['时间', '选手', '赛事名称'] # Define the schema for entity extraction

ie = Taskflow('information_extraction', schema=schema)

pprint(ie("2月8日上午北京冬奥会自由式滑雪女子大跳台决赛中中国选手谷爱凌以188.25分获得金牌！"))

输出：
[{}]

建议结合环境参考官网安装稳定的paddle版本 https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/install/pip/linux-pip.html

我的也是，我在aistudio 上也测试了，也为[{}] 。有说是版本的问题，我这paddlenlp2.5.2 panddlepaddle2.5.1 都是最新版本。不知道哪里有问题。官方给个答复呗
