gensim简单使用

gensim简单使用

首先是安装，看了网上各种教程，需要先按顺序安装numpy、scipy以及smartopen，最后才是gensim，另外有博主说numpy需要mkl版本。

不过我自己电脑上已经有各种所需要的库了，直接pip install gensim就行了。

中途碰到过问题：

①模型训练参数没有“size”的属性，目前是采取去掉这一参数

②gensim导入出现scipy报错：cannot import name '_ccallback_c' from 'scipy._lib'；反复卸载重装都没用，最终将E盘（Python所在的盘）中安装的上述三个库全部卸载，同时保有对应Python project中虚拟环境中三个库，就能好好运行了。

简单使用：

from gensim.models import word2vec
import gensim

sentences = word2vec.LineSentence("E:文档研二小论文医药制造业医药制造业年报gensim整合.txt")
model = word2vec.Word2Vec(sentences, hs=1, min_count=1, window=3)

model.save('model')  # 保存模型
model = word2vec.Word2Vec.load('model')  # 加载模型

for val in model.wv.similar_by_word("化工企业", topn=100):
    val_list = [val]
    print(val_list)
    pass

最终得到我想要的结果：“化工企业”对应的前100个相似词
