UnpicklingError：无效的加载键，'3'

Question

我正在创建一个聊天机器人。所以，我需要二进制格式的 word2vec 文件。 当我加载 bin 文件时，我得到了这种类型的错误。

import gensim

model = gensim.models.Word2Vec.load('GoogleNews-vectors-negative300.bin')

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/surya/anaconda3/lib/python3.6/site-packages/gensim/models/word2vec.py", line 975, in load
return super(Word2Vec, cls).load(*args, **kwargs)
File "/home/surya/anaconda3/lib/python3.6/site-packages/gensim/models/base_any2vec.py", line 629, in load
model = super(BaseWordEmbeddingsModel, cls).load(*args, **kwargs)
File "/home/surya/anaconda3/lib/python3.6/site-packages/gensim/models/base_any2vec.py", line 278, in load
return super(BaseAny2VecModel, cls).load(fname_or_handle, **kwargs)
File "/home/surya/anaconda3/lib/python3.6/site-packages/gensim/utils.py", line 395, in load
obj = unpickle(fname)
File "/home/surya/anaconda3/lib/python3.6/site-packages/gensim/utils.py", line 1302, in unpickle
return _pickle.load(f, encoding='latin1')_pickle.

UnpicklingError: invalid load key, '3'.

Answer 1

如果是二进制文件，需要这样写：

import gensim.models.keyedvectors as word2vec
model = word2vec.KeyedVectors.load_word2vec_format('GoogleNews-vectors-negative300.bin', binary=True)
