python - yellowbrick visualiser.fit() 引发 ValueError

Question

我正在尝试为我的 Twitter 数据可视化离散图

这是数据集的链接

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()

我试图在存储在 ht_negative_unnest 中的上述代码中传递这样的列表

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

出现的错误

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

Answer 1

我认为 wso 在您的语料库中找不到；只有#wso。

你试过像['love']这样的单一目标词吗？你仍然得到错误吗？
