如何手动将单词和矢量添加到Word2vec gensim

Question

比方说，word2vec.model是我训练过的word2vec模型。当出现词汇表外单词(oov_word(时，我使用compute_vec(oov_wword(方法计算向量vec。现在，我想将oov_word及其相应的向量vec添加到我已经训练好的模型word2vec.model中。

我已经检查了以下链接。但他们没有回答我的问题。

Answer 1

from gensim.models.keyedvectors import WordEmbeddingsKeyedVectors
vector_length = 100
kv = WordEmbeddingsKeyedVectors(vector_length)
# wordList - list of words
# vectorList - list of the vector corresponding to the words
kv.add(wordList, vectorList)
kv.most_similar(word1) # gives the list of words similar to word1
