AttributeError: type object 'Word2Vec' has no attribute 'load_word2vec_format'

Question

I am trying to implement word2vec model and getting Attribute error

AttributeError: type object 'Word2Vec' has no attribute 'load_word2vec_format'

Below is the code :

wv = Word2Vec.load_word2vec_format("GoogleNews-vectors-negative300.bin.gz", binary=True)
wv.init_sims(replace=True)

Please let me know the issue ?

Solution 1

gensim.models.KeyedVectors.load_word2vec_format("GoogleNews-vectors-negative300.bin.gz", binary=True)

try to upgrade all dependencies of gensim(e.g. smart_open), if you still have errors as follows

pip install --upgrade gensim

File "/home/liangn/PythonProjects/DeepRecommendation/Algorithm/Word2Vec.py", line 18, in init self.model = gensim.models.KeyedVectors.load_word2vec_format(w2v_path, binary=True)

File "/home/liangn/PythonProjects/venvLiang/lib/python2.7/site-packages/gensim/models/keyedvectors.py", line 191, in load_word2vec_format with utils.smart_open(fname) as fin:

Solution 2

How did you install gensim, and what version is installed?

API changes in (currently pre-release) gensim 1.0 move load_word2vec_format() to a helper class called KeyedVectors.

At this point (February 2017) you probably don't want to be using a pre-release version unless you're an experienced gensim user and closely follow the release-notes [CHANGELOG.md][1].

If intentionally using a later version of gensim with this API change, you would instead use:

KeyedVectors.load_word2vec_format("GoogleNews-vectors-negative300.bin.gz", binary=True)

I am new to gensim and using 1.0.0rc2. I tried using KeyedVector: import KeyedVectors KeyedVectors.load_word2vec_format("GoogleNews-vectors-negati‌​ve300.bin.gz", binary=True) but still I am getting the error. I am using Python 2.7, should I upgrade to Anaconda as some packages works good there

How did you install gensim? I don't believe pip install gensim would get you that pre-release version. What actual error are you getting after trying to use KeyedVector? (It can't possible be the same error, and the exact messages matter for solving.)
