建议安装：

pip install pyLDAvis==2.1.2

否则会报错：FileNotFoundError: [Errno 2] No such file or directory: 'https://cdn.jsdelivr.net/gh/bmabey/pyLDAvis@3.3.1/pyLDAvis/js/ldavis.v1.0.0.css'

使用示例

运行pyLDAvis示例：

import pyLDAvis.gensim
from gensim import corpora
from gensim.models import ldamodelsentence_list = [['青绿色', '放', '几天', '塑料袋', '里', '刺鼻', '气味', '药水', '味道', '说', '选择', '应季', '水果', '最佳', '踩', '雷', '水果'],['徒有其表', '皮厚肉', '渣', '一点', '甜', '入口', '评论', '欺骗', '消费者'], ['果子', '全是', '伤', '放', '烂', '几个', '放', '烂', '几个'],['路边', '两块钱', '一斤', '橙子', '没什么', '区别', '水分', '甜度', '称为', '品牌', '京东', '买', '水果', '三思'],['橙子', '酸', '一点', '不值'], ['垃圾', '沒', '水份', '别买'], ['质量', '太差', '坏', '吃'],['杨氏', '真', '买', '砸', '招牌', '皮厚肉', '干麻'],['生鲜', '越来越', '不行', '一点', '品质', '售后服务', '可言'],['买', '箱来', '送', '反馈', '说', '干', '京东', '搞', '飞机', '害人不浅'],['橙子', '品质', '太差', '三个', '霉变'],['新鲜', '橙子', '两头', '干枯', '水分', '新货']
]
# 训练 LDA
lda_dictionary = corpora.Dictionary(sentence_list)
lda_corpus = [lda_dictionary.doc2bow(sentence) for sentence in sentence_list]
lda_model = ldamodel.LdaModel(corpus=lda_corpus, id2word=lda_dictionary, num_topics=4)
# 使用 pyLDAvis
vis_data = pyLDAvis.gensim.prepare(lda_model, lda_corpus, lda_dictionary)
pyLDAvis.show(vis_data, open_browser=False)
pyLDAvis.save_html(vis_data, 'save_local.html')

如果无特殊方法，可能无法下载这三个文件：

https://cdn.rawgit.com/bmabey/pyLDAvis/files/ldavis.v1.0.0.css
https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.5/d3.min
https://cdn.rawgit.com/bmabey/pyLDAvis/files/ldavis.v1.0.0.js

三份文件与绘图实例，可以到博主上传的文件这里免费下载：https://download.csdn.net/download/weixin_35757704/82465448

可以把这三个文件下载到本地，然后修改save_local.html文件的路径即可
