无法重新创建用于训练 FastText 的 Gensim 文档。类型错误：必须提供 corpus_file 或 corpus_iterable 值之一

Question

我正在尝试制作我自己的 Fasttext 嵌入，所以我去了官方 Gensim 文档并在下面使用确切4.0版本实现了这个确切的代码。

from gensim.models import FastText
from gensim.test.utils import common_texts

model = FastText(vector_size=4, window=3, min_count=1)  # instantiate
model.build_vocab(sentences=common_texts)
model.train(sentences=common_texts, total_examples=len(common_texts), epochs=10)

令我惊讶的是，它给了我以下错误：

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-4-6b2d1de02d90> in <module>
      1 model = FastText(vector_size=4, window=3, min_count=1)  # instantiate
----> 2 model.build_vocab(sentences=common_texts)
      3 model.train(sentences=common_texts, total_examples=len(common_texts), epochs=10)

    480         total_words, corpus_count = self.scan_vocab(
    481             corpus_iterable=corpus_iterable, corpus_file=corpus_file, progress_per=progress_per, trim_rule=trim_rule)

   1487         if corpus_file is not None and corpus_iterable is not None:
   1488             raise TypeError("Both corpus_file and corpus_iterable must not be provided at the same time")

TypeError: Either one of corpus_file or corpus_iterable value must be provided

有人可以帮助这里发生的事情吗？

Answer 1

所以我找到了这个问题的答案。他们对sentence两者的论点都有问题：

model.build_vocab(sentences=common_texts)
model.train(sentences=common_texts, total_examples=len(common_texts), epochs=10)

您所要做的就是删除参数名称或简单地传递第一个参数corpus_iterable

model.build_vocab(common_texts)
model.train(common_texts, total_examples=len(common_texts), epochs=10)

或者

model.build_vocab(corpus_iterable=common_texts)
model.train(corpus_iterable=common_texts, total_examples=len(common_texts), epochs=10)
