# how to update the pre-trained word2vec model with new train data using genism

Hi I have used the genism to load the Spanish fasttext word2vec model with following code:

Word2Vec = KeyedVectors.load_word2vec_format('../data/raw/wiki.es.vec',
binary=False)


and now I want to train the word2vec with new training sentences.

I know that in the genism can use the following code to train new sentences if the model is loaded:

 model.build_vocab(sentences)  # prepare the model vocabulary
model.train(sentences, )


But how to update the model if I used the KeyedVectors.load_word2vec to load the model.

Thanks!
