Error while loading Word2Vec model in gensim
提问by Tarantula
I'm getting an AttributeErrorwhile loading the gensim model available at word2vec repository:
我正在AttributeError加载 word2vec 存储库中可用的 gensim 模型：
from gensim import models
w = models.Word2Vec()
w.load_word2vec_format('GoogleNews-vectors-negative300.bin', binary=True)
print w["queen"]
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-3-8219e36ba1f6> in <module>()
----> 1 w["queen"]
C:\Anaconda64\lib\site-packages\gensim\models\word2vec.pyc in __getitem__(self, word)
761
762 """
--> 763 return self.syn0[self.vocab[word].index]
764
765
AttributeError: 'Word2Vec' object has no attribute 'syn0'
Is this a known issue ?
这是一个已知的问题 ？

Fixed the problem with:
修复了以下问题：
from gensim import models
w = models.Word2Vec.load_word2vec_format('GoogleNews-vectors-negative300.bin', binary=True)
print w["queen"]

In order to share word vector querying code between different training algos(Word2Vec, Fastext, WordRank, VarEmbed) the authors have separated storage and querying of word vectors into a separate class KeyedVectors.
为了在不同的训练算法（Word2Vec、Fastext、WordRank、VarEmbed）之间共享词向量查询代码，作者将词向量的存储和查询分离到一个单独的类 KeyedVectors 中。
Two methods and several attributes in word2vec class have been deprecated.
word2vec 类中的两个方法和几个属性已被弃用。
Methods
方法
- load_word2vec_format
- save_word2vec_format
- load_word2vec_format
- save_word2vec_format
Attributes
属性
- syn0norm
- syn0
- vocab
- index2word
- 同义词
- 同步
- 词汇
- 索引二字
These have been moved to KeyedVectors class.
这些已移至 KeyedVectors 类。
After upgrading to this release you might get exceptions about deprecated methods or missing attributes.
升级到此版本后，您可能会收到有关已弃用方法或缺少属性的异常。
To remove the exceptions, you should use
要删除异常，您应该使用
KeyedVectors.load_word2vec_format (instead ofWord2Vec.load_word2vec_format)
word2vec_model.wv.save_word2vec_format (instead of word2vec_model.save_word2vec_format)
model.wv.syn0norm instead of (model.syn0norm)
model.wv.syn0 instead of (model.syn0)
model.wv.vocab instead of (model.vocab)
model.wv.index2word instead of (model.index2word)

Currently, as models.Word2Vechas been deprecated, you need to use the models.KeyedVectors.load_word2vec_formatinstead of models.Word2Vec.load_word2vec_formatas shown below.
目前，由于models.Word2Vec已被弃用，您需要使用models.KeyedVectors.load_word2vec_format代替 ，models.Word2Vec.load_word2vec_format如下所示。
from gensim import models
w = models.KeyedVectors.load_word2vec_format('model.bin', binary=True)
