问题描述
byte在这里，我有一个名为sbyte的系列，其中删除了停用词，被import pandas as pd
import matplotlib.pyplot as plt
% matplotlib inline
import spacy
from wordcloud import WordCloud,STOPWORDS,ImageColorGenerator
nlp= spacy.load('en_core_web_sm')
并进行了合法化
tokens_lemma我想使用以上系列创建一个wordcloud。
.lower()我个人认为问题来自tokens_lemma

对象，因为wordcloud的数据格式错误。但是同样，我不知道如何更改以匹配wordcloud格式。
解决方法
在写完问题后，我不小心解决了问题，所以我还是要发布它。
只需将数据从for w in tokens_lemma:
w=str(w)
comment_words += " ".join(w)
wordcloud = WordCloud(width = 800,height = 800,background_color ='white',min_font_size = 10).generate(comment_words)
# plot the WordCloud image
plt.figure(figsize = (8,8),facecolor = None)
plt.imshow(wordcloud)
plt.axis("off")
plt.tight_layout(pad = 0)
plt.show()

更改为comment_words就可以了。
comment_words
