gensim介绍:python NLP的包
gensim包依赖于numpy包和scipy包,即需要先安装numpy和scipy,再安装gensim
【word2vec】
# 参考https://radimrehurek.com/gensim/models/word2vec.html
from gensim.test.utils import common_texts, get_tmpfile # common_texts表示gensim包自带的可训练数据
from gensim.models import Word2Vec
from gensim.models import KeyedVectors
from gensim.test.utils import datapath
path = get_tmpfile("word2vec.model")
model = Word2Vec(common_texts, size=100, window=5, min_count=1, workers=4) # word2vec中最重要的一条语句, size表示维数
model.save("word2vec.model") # 【保存】模型
model = Word2Vec.load("word2vec.model") # 【加载(方式1)】模型(需要继续训练时)
model.train([["hello", "world"]], total_examples=1, epoc
