ImportError:[E048]无法从spacy.lang导入语言自定义\u en:没有名为“spacy.lang.custom\u en”的模块

Question

在spacy 3.0中，我注册了如下自定义语言：

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")，效果很好。 但是当我在config.cfg文件中使用lang="custom-en"并使用命令时：

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

我得到以下错误：

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

  File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'spacy.lang.custom_en'

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