我在pytrend查询中没有收到正确的答案

Question

我打算使用pytrend接收有关“大数据工具” bt的建议。我的脚本在下面，输出与主题无关。你有什么主意吗？

from pytrends.request import TrendReq

pytrend = TrendReq(hl='en-US', tz=360)

kw_list = ["Big data tools","big data platforms"]  
_cat = 0
_geo = ''
_gprop = ''
_timeframe = 'all'

pytrend.build_payload(kw_list, cat=_cat, timeframe=_timeframe, geo=_geo, gprop=_gprop)

suggestions_dict = pytrend.suggestions(keyword='Big Data Tools') 
suggestions_dict 

输出：

 [{'mid': '/m/012d40', 'title': 'Jackie Chan', 'type': 'Martial artist'},
 {'mid': '/m/04v7kt', 'title': 'Idris Elba', 'type': 'Actor'},
 {'mid': '/m/03sc8', 'title': 'IBM', 'type': 'Computer hardware company'},
 {'mid': '/m/0tj9', 'title': 'Amitabh Bachchan', 'type': 'Indian film actor'},
 {'mid': '/m/01vz0g4',
 'title': 'The Notorious B.I.G.',
 'type': 'American rapper'}]
