Cause:

Originally, there was a saved_model folder under the two folders sort_change_nlp and sort_nlp, but the names were different, one was saved_model and the other was saved_model_copy. Using saved_model in http_sever clock, the following error occurred:

model = YesOrNoModel.from_pretrained(model_name)

def is_model_answer(query):
    for rule in base_data.q_v_model_list:
        result1 = re.compile(rule).findall(query)
        if len(result1):
            return "saved_model"
    return ""
  model_name = is_model_answer(query)
    print(f"model_name={model_name}，answer={answer}")
    if len(model_name):
        model = YesOrNoModel.from_pretrained(model_name)

OSError: Can't load config for 'saved_model'. Make sure that:
- 'saved_model' is a correct model identifier listed on 'https://huggingface.co/models'
- or 'saved_model' is the correct path to a directory containing a config.json file

Solution:
The reason is that http.server is a level folder with sort_change_nlp and sort_nlp, so the path passed in when calling the model should be: sort_change_nlp/saved_model or sort_nlp, saved_model_copy
