本以为开开心心地就能用了，然而一运行代码报错：

卸载刚装的 pyLDAvis==3.3.1

安装指定版本 pyLDAvis==2.1.2。

pip install pyLDAvis==2.1.2 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

或者不用安装旧版本，用新版本的方法：

import pyLDAvis.gensim_models as gensimvis
from pyLDAvis import gensim


pyLDAvis.enable_notebook()

'''
lda: 计算好的话题模型

corpus: 文档词频矩阵

dictionary: 词语空间
'''
d = gensim.prepare(lda,corpus,dictionary)
d = gensimvis.prepare(lda,corpus,dictionary)
pyLDAvis.display(d)		    # 展示在浏览器
# pyLDAvis.save_html(p, 'lda.html')

利用 pyLDAvis.save_html(p, ‘lda.html’) 方法可以将可视化结果保存为单独的 HTML 文件。
