how to know vectors dimension in word2vec model

[David Batista]

Hello everyone,

I'm doing a few experiments using models of different dimensions created with the word2vec tool by Mikolov.

Is there a way to know the number of dimensions of each model?
I looked through the API and code but did not find anything (maybe I miss something)

Thank you,
David

Hi David,

if you mean in the model file -- the number of dimensions is on the first line = the header line. It's the second number there. (The first number is the vocabulary size.)

If you mean in a Python model object -- try `model.layer1_size`.

Hope that helps,

Radim

Hi Radim,

I meant the Python object. Thank you for your answer :)

same question here, did you manage to figure out how to find the size of the word2vec model?

ps: wow this is long time ago!

Hi Nawras,

It's as simple as model.vector_size
See the docs at http://radimrehurek.com/gensim/models/word2vec.html
