gensim 入门错误：没有这样的文件或目录：'text8'

Question

我正在学习 python 中的 word2vec 和 GloVe 模型，所以我正在浏览这个可用的here。

我在 Idle3 中一步步编译这些代码后：

>>>from gensim.models import word2vec
>>>import logging
>>>logging.basicConfig(format='%(asctime)s : %(levelname)s : %(message)s', level=logging.INFO)
>>>sentences = word2vec.Text8Corpus('text8')
>>>model = word2vec.Word2Vec(sentences, size=200)

我收到此错误：

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: 'text8'

我该如何纠正这个问题？ 提前感谢您的帮助。

Answer 1

您似乎缺少此处使用的文件。具体来说，它正在尝试打开text8，但找不到它（因此是FileNotFoundError）。

您可以按照in the documentation for Text8Corpus 的说明从here 下载文件本身：

Docstring:      
Iterate over sentences from the "text8" corpus, unzipped from http://mattmahoney.net/dc/text8.zip .

并使其可用。 提取它，然后将其作为参数提供给Text8Corpus：

sentences = word2vec.Text8Corpus('/path/to/text8')
