FastText: TypeError: loadModel(): incompatible function arguments

Question

编辑：正在处理 Windows

我只想加载一个已下载的 fasttext 嵌入模型，但出现错误（见底部）我找不到解决方案。这是代码：

import fasttext
from pathlib import Path

base_path = Path("..")
fasttext_model = base_path / "models" / "cc.de.300.bin"

class EmbeddingVectorizer:
    def __init__(self):

        self.embedding_model = fasttext.load_model(fasttext_model)

    def __call__(self, doc):
        """
        Convert address to embedding vectors
        :param address: The address to convert
        :return: The embeddings vectors
        """
        embeddings = []
        for word in doc:
            embeddings.append(self.embedding_model[word])
        return embeddings

embedding_model = EmbeddingVectorizer()

这是错误：

TypeError: loadModel(): incompatible function arguments. The following argument types are supported:
    1. (self: fasttext_pybind.fasttext, arg0: str) -> None

Invoked with: <fasttext_pybind.fasttext object at 0x0000016C630257B0>, WindowsPath('../models/cc.de.300.bin')

fasttext 的文档没有给我任何可能出错的线索。有什么猜测吗？谢谢！

Answer 1

提供字符串，而不是 Path 对象。

根据错误...

TypeError: loadModel(): incompatible function arguments. The following argument types are supported:
    1. (self: fasttext_pybind.fasttext, arg0: str) -> None

Invoked with: <fasttext_pybind.fasttext object at 0x0000016C630257B0>, WindowsPath('../models/cc.de.300.bin')

...arg0（第一个位置参数）应该是 str，它看到的是 WindowsPath 对象。

可能只使用 str(facebook_model) 而不是 facebook_model 作为 fasttext.load_model().

的参数就足够了

但是如果您对 fasttext 代码实际指向的位置有任何进一步的混淆，您也可以查看并尝试 str(facebook_model.resolve())，这样您一定会看到绝对文件的完整路径。
