Gensim中doc2vec标记中的问题 [英] Issues in doc2vec tags in Gensim

问题描述

我正在使用gensim doc2vec，如下所示.

I am using gensim doc2vec as below.

from gensim.models import doc2vec
from collections import namedtuple
import re

my_d = {'recipe__001__1': 'recipe 1 details should come here',
 'recipe__001__2': 'Ingredients of recipe 2 need to be added'}
docs = []
analyzedDocument = namedtuple('AnalyzedDocument', 'words tags')
for key, value in my_d.items():
    value = re.sub("[^a-zA-Z]"," ", value)
    words = value.lower().split()
    tags = key
    docs.append(analyzedDocument(words, tags))
model = doc2vec.Doc2Vec(docs, size = 300, window = 10, dm=1, negative=5, hs=0, min_count = 1, workers = 4, iter = 20)

但是，当我检查model.docvecs.offset2doctag时，将得到['r', 'e', 'c', 'i', 'p', '_', '0', '1', '2']作为输出.实际输出应为"recipe__001__1"和"recipe__001__2".

However, when I check model.docvecs.offset2doctag I get ['r', 'e', 'c', 'i', 'p', '_', '0', '1', '2'] as the output. The real output should be `'recipe__001__1' and 'recipe__001__2'.

当我使用len(model.docvecs.doctag_syn0)时，我得到9作为输出.但是实际值应该为2，因为我的测试字典中只有2个配方.

When I use len(model.docvecs.doctag_syn0) I get 9 as the output. But the real value should be 2 because I only have 2 recipes in my test dictionary.

请让我知道，为什么会这样?

Please let me know, why this happens?

推荐答案

尝试更改此行:

tags = key

到

tags = [key]
