chatbot error: [E941] Can‘t find model ‘en‘

今天尝试运行一个chatbot的demo，创建实体时报错：

Traceback (most recent call last):

OSError: [E941] Can't find model 'en'. It looks like you're trying to load a model from a shortcut, which is deprecated as of spaCy v3.0. To load the model, use its full name instead:

nlp = spacy.load("en_core_web_sm")

For more details on the available models, see the models directory: https://spacy.io/models. If you want to create a blank model, use spacy.blank: nlp = spacy.blank("en")
           

其实个人感觉是包和包之间的冲突，spacyV3.0以后不再支持“en”这样简单的引用，期待全名称“en_core_web_sm”引用。而chatbot则未能跟进，源码中保持尝试“en”这样的deprecated的shortcut。

解决方法：

进入py环境下chatbot包中的tagging.py模块，将报错信息中提到的这句：

self.nlp = spacy.load(self.language.ISO_639_1.lower())
           

更改为：

if self.language.ISO_639_1.lower() == 'en':
    self.nlp = spacy.load('en_core_web_sm')
else:
    self.nlp = spacy.load(self.language.ISO_639_1.lower())
           

重新加载后问题解决。
