如何在chatbot python flask中返回空响应?

from chatterbot import ChatBot from chatterbot.trainers import ListTrainer chatterbot = ChatBot("Training Example") chatterbot.set_trainer(ListTrainer) chatterbot.train([ "Hi there!", "Hello", ]) chatterbot.train([ "Greetings!", "Hello", ]) chatbot.train(["Greetings!","Hello",]) chatbot.train(["How are you?","I am good.","That is good to hear.","Thank you","You are welcome.",]) while True: try: a = input("question please..? ") response = chatterbot.get_response(a) print(response) except (KeyboardInterrupt,SystemExit): print("your loop has been closed: ") break

LowConfidenceAdapter 如果无法以高置信度确定响应,则可用于返回默认响应。
设置一个 threshold 值作为响应的最小置信分数。如果信心低于这个 门槛 值时,它将返回默认响应。

使用更新的代码 LowConfidenceAdapter :

from chatterbot import ChatBot

from chatterbot.trainers import ListTrainer
chatbot = ChatBot("Training Example",
                  logic_adapters=[
                    {
                        'import_path': 'chatterbot.logic.BestMatch'
                    },
                    {
                        'import_path': 'chatterbot.logic.LowConfidenceAdapter',
                        'threshold': 0.65,
                        'default_response': 'I am sorry, but I do not understand.'
                    }
                ])

chatbot.set_trainer(ListTrainer)

chatbot.train([
    "Hi there!",
    "Hello"])

chatbot.train([
    "Hello",
    "Hey!"])

chatbot.train([
    "How are you?",
    "I am good."])
chatbot.train([    
    "That is good to hear.",
    "Thank you",
    "You are welcome."])
chatbot.train([
    "Sure, I'd like to book a flight to Iceland.",
    "Your flight has been booked."])

while True:
    try:
        a = input("Question please..? ")
        response = chatbot.get_response(a)
        print(response)
    except (KeyboardInterrupt,SystemExit):
        print("\nYour loop has been closed.")
        break

输出:
