Wordcloud 未生成图像

问题描述

#what is the most frequent words?

data['document_content']=data['document_content'].apply(lambda x:"".join(x.lower() for x in x.split()))
data['document_content']=data['document_content'].str.replace('[^\w\s]',' ')
data['document_content']=data['document_content'].str.replace('\d',' ')

#stopwords
import nltk
nltk.download('stopwords')
from nltk.corpus import stopwords
sw=stopwords.words('english')
data['document_content']=data['document_content'].apply(lambda x: " ".join(x for x in x.split() if x not in sw))

#lemma
from textblob import Word
nltk.download('wordnet')
data['document_content']=data['document_content'].apply(lambda x:" ".join([Word(word).lemmatize() for word in x.split()]))

#punctuation
data['document_content']=data['document_content'].str.replace("rt"," ")

data['document_content'].head()

from os import path
from PIL import Image
from wordcloud import WordCloud,STOPWORDS,ImageColorGenerator
import matplotlib.pyplot as plt

text="".join(i for i in data.document_content)

wc=WordCloud(background_color="black").generate(str(data.document_content))
plt.imshow(wc,interpolation="bilinear")
plt.axis("off")
plt.tight_layout(pad=1)
plt.show()

但它不返回图像而只返回 "Canvas(toolbar=Toolbar(toolitems=[('Home','Reset original view','home','home'),('Back','Back to prevIoUs ..."

不知道我应该如何更改代码 你能帮我解决这个问题吗？
