get (AttributeError:在Gensim 4.0.0中从keyevector中删除了vocab属性)使用类

Question

我有一个python类特性器，检查是否存在(Google新闻向量嵌入文件)，如果存在则加载，否则抛出错误消息。问题是当我试图加载它时，我得到一个关于attributeerror的错误，我不知道要改变什么。

尝试加载文件嵌入

from gensim.models import KeyedVectors
from gensim import models
word2vec_path = 'D:mt 111QuestionAnswerGoogleNews-vectors-negative300.bin'

这个类检查嵌入文件

是否存在。

class Featurizer:
def __init__(self, embedding_file):
if not os.path.exists(embedding_file):
raise IOError("Embeddings file does not exist: %s" %embedding_file)
punctuation = string.punctuation
punctuation = punctuation + "’" + "“" + "?" + "‘"
self.punctuation = punctuation
print('INFO: Loading word vectors...')
self.word2vec = KeyedVectors.load_word2vec_format(
embedding_file,
binary=True)
print('INFO: Done! Using %s word vectors from pre-trained word2vec.' 
%len(self.word2vec.vocab))

当使用类特性器加载嵌入时

featurizer = Featurizer(word2vec_path)

返回一个关于

类的错误

可能是什么问题，我如何纠正它。

在你的class init中，embedding_file值是一个字符串，但你在初始化你的类时给了它另一种数据类型(键值向量)，所以不是这样:

featurizer = Featurizer(w2v_model) 

你应该这样使用SMTH:

featurizer = Featurizer(word2vec_path)
