Question

我想使用gensim使用python -m gensim.scripts.make_wiki脚本将Wikipedia转储转换为纯文本。

我用它作为：

python -m gensim.scripts.make_wiki ./enwiki-latest-pages-articles.xml.bz2 ./results

最后给我一个错误：

2016-04-06 20:43:46,471 : INFO : storing corpus in Matrix Market format to ./results/_bow.mm

有人知道发生了什么吗？

不确定命令行脚本，但以下内容适用于我 -

def parse_wiki(wiki_bz_file):
    output = open('./wiki_text_dump.txt', 'w')
    i = 0
    wiki = WikiCorpus(wiki_bz_file, lemmatize=False, dictionary={}) #vocab dict not needed
    for text in wiki.get_texts():
        output.write(u.listToStr(chunk) + '\n')
        i = i + 1
        if i%50000 == 0:
            logger.info("Saved " + str(i) + " articles")
    output.close()
    logger.info("Finished Saved " + str(i) + " articles")
    return

使用python -m gensim.scripts.make_wiki将Wikipedia转储转换为文本
