use a.all() or a.any() error while trying to use gensim word2vec

Question

I've been trying to run an example of how t use word2vec from the gensim library of python but I keep getting this error

    ValueError: The truth value of an array with more than one element is   ambiguous. Use a.any() or a.all()

This is my code, it's just a simple example :

    from gensim.models import Word2Vec
    sentences = [['first', 'sentence'], ['second', 'sentence']]
    # train word2vec on the two sentences
    model = Word2Vec(sentences, min_count=1)

Note: I've made sure that gensim is installed with all its dependencies.

Answer 1

I had the same exact problem too, what i did was installing python-dev package then re-installing gensim, somehow that worked, i'm on ubuntu so this is what i did :

sudo apt-get install python-dev
sudo pip uninstall gensim
sudo pip install gensim

when i run this :

model = gensim.models.Word2Vec(sentences=listSentence,min_count=2,window=3,size=20,workers=1)
print model['Brasil']

it worked and i got the result vector :
