【问题描述】：

我尝试在本地机器上重现 this tutorial 以适应 gensim fasttext 功能。 Fasttext 和 gensim 库已正确安装。通过调用gensim fasttext wrapper的train方法

model_wrapper = FT_wrapper.train(ft_home, lee_train_file)

我收到以下错误：

---------------------------------------------------------------------------

PermissionError: [Errno 13] Permission denied: '/Users/marcomattioli/fastText'

请注意，我对 fasttext 可执行文件具有 -rwxr-xr-x 权限。任何帮助感谢如何解决这个问题。

【解决方案1】：

这些方法已弃用。

使用以下代码：

from gensim.models.fasttext import FastText
from gensim.test.utils import datapath
corpus_file = datapath('lee_background.cor')  # absolute path to corpus
model3 = FastText(size=4, window=3, min_count=1)
model3.build_vocab(corpus_file=corpus_file)
total_words = model3.corpus_total_words
model3.train(corpus_file=corpus_file, total_words=total_words, epochs=10)
