导入错误：[E048] 无法从 spacy.lang 导入语言 custom_en：没有名为“spacy.lang.custom_en”的模块

问题描述

在 spacy 3.0 中，我已经注册了我的自定义语言，如下所示：

import spacy
from spacy.lang.en import English

class CustomEnglishDefaults(English.Defaults):
    stop_words = set(["custom","stop"])

@spacy.registry.languages("custom_en")
class CustomEnglish(English):
    lang = "custom_en"
    Defaults = CustomEnglishDefaults

我试过代码行 nlp = spacy.blank("custom_en") 并且它工作正常。 但是当我在 lang="custom-en" 文件中使用 config.cfg 并使用命令时：

python -m spacy train config.cfg --paths.train ./train.spacy --paths.dev ./dev.spacy

我收到以下错误：

Traceback (most recent call last):
  File "/home/marzi/anaconda3/envs/spacy-tutorial/lib/python3.8/site-packages/spacy/util.py",line 244,in get_lang_class

The above exception was the direct cause of the following exception:

我该如何解决这个问题？
