yellowbrick visualiser.fit（）引发了ValueError

Question

我正在尝试为我的Twitter数据可视化分散图

Here is the link to the datset

dataset

这是代码

from yellowbrick.text import DispersionPlot

text = combine['tweet']
target_words = ht_negative_unnest

visualizer = DispersionPlot(target_words)
visualizer.fit(text)
visualizer.poof()

我试图在ht_negative_unnest中存储的上述代码中传递这样的列表

 ['cnn',
     'michigan',
     'tcot',
     'australia',
     'opkillingbay']

提出错误

YellowbrickValueError: The indexed word 'wso' is not found in this corpus

Answer 1

我认为你的语料库中找不到wso;只有#wso。

你尝试过像''love'这样的目标单词吗？你还得到错误吗？
