报错原因
gensim 4 版本与 gensim3不同的使用方法。
解决方法
降低版本(不推荐)
安装gensim3版本
pip install gensim==3.2 按照gensim4的使用方法来用
model = Word2Vec(sentences, min_count=1) ## 原始代码：报错地点 print(model['sentence']) ## 修改后的代码 print(model.wv['sentence']) 整体代码(使用gensim通过模块训练获得词向量)
from gensim.models import Word2Vec # define training data sentences = [['this', 'is', 'the', 'first', 'sentence', 'for', 'word2vec'], ['this', 'is', 'the', 'second', 'sentence'], ['yet', 'another', 'sentence'], ['one', 'more', 'sentence'], ['and', 'the', 'final', 'sentence']] # train model model = Word2Vec(sentences, min_count=1) # summarize the loaded model
print(model)
# summarize vocabulary
words = list(model.wv.key_to_index)
print(words)
# access vector for one word
print(model.wv['sentence'])
# save model
model.save('model.bin')
# load model
new_model = Word2Vec.load('model.bin')
print(new_model)
