我正在尝试使用磁盘中的自定义管道加载自定义预训练模型作为 spacy 3.0 中的管道：

工厂的代码是这样的：

@CustomEng.factory("ner-crf")
def create_my_component(nlp, name):
    crf_extractor = CRFExtractor().from_disk("path-to-model")
    return CRFEntityExtractor(nlp, crf_extractor=crf_extractor)

然后我将“ner-crf”添加到我的语言类中，如下所示：

    nlp = spacy.blank('custom-eng')
    nlp.add_pipe('ner-crf')
    nlp.to_disk('../model')

我认为有一件事可能是相关的：当我使用to_disk以保存对象时，保存的nlp对象中没有ner-crf包（我刚刚添加的管道）。

然后我运行这个 CLI 命令来评估 NER 管道：

python -m spacy evaluate ../model/ ../corpus/dev.spacy --output ../model/metrics.json --gpu-id 0 --code ../../../spacy_utils/custom-eng/__init__.py

但我得到这个错误：

TypeError: from_disk() got an unexpected keyword argument 'exclude'

我使用的自定义 NER 类属于spacy-crfsuite库，该库在 spacy 2 中运行良好，但它们还没有用于 Spacy 3 的示例代码，所以我自己试图让它在 spacy 3.0 中运行。

从 spaCy v3.0 开始，管道组件有望在其方法上支持exclude关键字。to_disk您可以将exclude关键字添加到您的函数中，给它一个默认值，并且根本不在函数体中使用它的值，并且应该解决此错误。

为了完整起见，这里是从 v2 过渡到 v3 的迁移指南，其中可能包括一些额外的有趣指针：https ://spacy.io/usage/v3#migrating
