Gensim: KeyedVectors.train()

I downloaded Wikipedia word vectors from here. I loaded the vectors with:

model_160 = KeyedVectors.load_word2vec_format(wiki_160_path, binary=False)

and then want to train them with:

model_160.train()

I get the error back:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-11-22a9f6312119> in <module>()
----> 1 model.train()

AttributeError: 'KeyedVectors' object has no attribute 'train'

My question is now: It seems like KeyedVectors has no train function, but I want to continue training the vectors on my personal sentences, instead of just using the Wikipedia vectors. How is this possible?

Thanks in advance, Jan

You can't use KeyedVectors for that. From the documentation:

Word vector storage and similarity look-ups.
The word vectors are considered read-only in this class.

And also:

The word vectors can also be instantiated from an existing file on disk in the word2vec C format as a KeyedVectors instance.
[...]
NOTE: It is impossible to continue training the vectors loaded from the C format because hidden weights, vocabulary frequency and the binary tree is missing.
