如何在 Python 中使用 textcat？

Question

我想尝试一下TextCat。如果我可以从 Python 运行它对我来说最方便，因为我想看看它在私有数据集上的表现如何。

我给了languagedet，但根据

from languagedet.mixed import MixedDetector
det = MixedDetector()
print(det.available)

远少于 TextCats 网站上声称的 69 种语言可通过 languagedet 获得。

我也试过pylibtextcat，但我得到：

当我尝试安装它时（我已经安装了libexttextcat-2.0-0, libexttextcat-data, libexttextcat-dev）。

我可以在 Python 中使用 TextCat 吗？

Seems not to be the same, but nltk has:

from nltk.classify import textcat

text = "This is a simple example."
cls = textcat.TextCat()

distances = cls.lang_dists(text)  # a dict of 437 elements
cls.guess_language(text)  # a str
