我正在尝试使用 httpapi 和 json 数据来训练模型,这就是代码。

import requests
import json

data = {
    "config": "language: en\npipeline:\n- name: WhitespaceTokenizer\n- name: RegexFeaturizer\n- name: LexicalSyntacticFeaturizer\n- name: CountVectorsFeaturizer\n- name: CountVectorsFeaturizer\nanalyzer: \"char_wb\"\nmin_ngram: 1\nmax_ngram: 4\n- name: DIETClassifier\nepochs: 100\n- name: EntitySynonymMapper\n- name: ResponseSelector\nepochs: 100",
    "nlu": json.dumps({
        "rasa_nlu_data": {
            "regex_features": [],
            "entity_synonyms": [],
            "common_examples": [
                {
                    "text": "i m looking for a place to eat",
                            "intent": "restaurant_search",
                            "entities": []
                },
                {
                    "text": "I want to grab lunch",
                            "intent": "restaurant_search",
                            "entities": []
                },
                {
                    "text": "I am searching for a dinner spot",
                            "intent": "restaurant_search",
                            "entities": []
                },
            ]
        }
    }),
    "force": False,
    "save_to_default_model_directory": True
}

r = requests.post('http://localhost:5005/model/train', json=data)

它给了我 500 错误。以下是错误日志:

当我使用终端命令和 json 文件训练模型时,它训练成功。我想我缺少/model/train api 所需的一些格式。有人可以告诉我我哪里出错了吗?

我正在使用 rasa 版本 1.10.14。

先感谢您。

原来配置中的字符串不正确。由于转义字符使用双引号,因此在训练模型时会出错。我在配置中做了一些调整,它成功地训练了模型
