Question

我正在使用gensim处理代码，并且很难在我的代码中对ValueError进行故障排除。我终于能够压缩GoogleNews-vectors-negative300.bin.gz文件了，所以我可以在我的模型中实现它。我也试过gzip，结果不成功。代码中的错误发生在最后一行。我想知道如何解决错误。有没有解决方法？最后，有一个我可以参考的网站吗？

谢谢你的帮助！

import gensim
from keras import backend
from keras.layers import Dense, Input, Lambda, LSTM, TimeDistributed
from keras.layers.merge import concatenate
from keras.layers.embeddings import Embedding
from keras.models import Mode

pretrained_embeddings_path = "GoogleNews-vectors-negative300.bin"
word2vec = 
gensim.models.KeyedVectors.load_word2vec_format(pretrained_embeddings_path, 
binary=True)

Answer 1

你必须写完整的路径。

使用此路径：

https://s3.amazonaws.com/dl4j-distribution/GoogleNews-vectors-negative300.bin.gz

Answer 2

以下命令有效。

brew install wget

wget -c "https://s3.amazonaws.com/dl4j-distribution/GoogleNews-vectors-negative300.bin.gz"

然后您可以使用以下命令获取 wordVector 。

from gensim import models

w = models.KeyedVectors.load_word2vec_format(
    '../GoogleNews-vectors-negative300.bin', binary=True)

Answer 3

尝试-

import gensim.downloader as api

wv = api.load('word2vec-google-news-300')

vec_king = wv['king']

导入GoogleNews-vectors-negative300.bin
