打开文本
text = open('xyj.txt').read()
中文分词
text = ' '.join(jieba.cut(text))
print(text[:100])生成对象
mask = np.array(Image.open("black_mask.png"))
wc = WordCloud(mask=mask, font_path='Hiragino.ttf', mode='RGBA', background_color=None).generate(text)显示词云
plt.imshow(wc, interpolation='bilinear')
plt.axis("off")
plt.show()保存到文件
wc.to_file('wordcloud4.png')
