Jupyter notebook:Wordcloud can't generate a word cloud

[ShuaiXiaoxi]

Hey,
I am using Jupyter notebook to create a word cloud, but I'm encountering some issues that I can't resolve. I've tried various methods online, but I'm still stuck.。

`ValueError Traceback (most recent call last)

31 index_positive = data['scores'] >= 30.0
32
---> 33 my_word_cloud(data['content'][index_negative],stoplist,'aixin.jpg') # 差评词云
34 my_word_cloud(data['content'][index_positive],stoplist,'aixin.jpg') # 好评词云

404 "got %d." % len(frequencies))
405 frequencies = frequencies[:self.max_words]

ValueError: We need at least 1 word to plot a word cloud, got 0.`
