gensim Getting Started Error: No such file or directory: 'text8'

Question

我正在 python 中学习 word2vec 和 GloVe 模型，所以我正在研究这个可用的 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)

我收到这个错误：

    return open(fname, mode)
FileNotFoundError: [Errno 2] No such file or directory: 'text8'

我该如何纠正这个问题？预先感谢您的帮助。

Answer 1

您似乎缺少此处使用的文件。具体来说，它试图打开 text8 但找不到它（因此 FileNotFoundError）。

您可以从 here as is stated in the documentation for Text8Corpus:

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。 提取它然后将它作为参数提供给Text8Corpus:

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