如果不用你上面的GPT-2模型,就用普通的python写,把代码补充完整

好的,以下是一个简单的示例代码,使用Python中的NLTK库实现基本的聊天机器人:
```python
import nltk
from nltk.chat.util import Chat, reflections
pairs = [
[
r"my name is (.*)",
["Hello %1, How are you today?"]
],
[
r"hi|hello|hey",
["Hello", "Hi there"]
],
[
r"what is your name?",
["My name is ChatBot. How can I help you?"]
],
[
r"how are you?",
["I'm doing well. How about you?"]
],
[
r"sorry (.*)",
["It's alright.", "It's OK, no problem."]
],
[
r"quit",
["Bye-bye. Take care!"]
],
[
r"(.*)",
["Sorry, I did not understand you. Can you please repeat?"]
]
]
def chatbot():
print("Hi. I'm your personal chatbot. You can talk to me by typing in English language. Type 'quit' to exit.")
chat = Chat(pairs, reflections)
chat.converse()
if __name__ == "__main__":
nltk.download('punkt')
nltk.download('averaged_perceptron_tagger')
chatbot()
```
在上面的代码中,我们使用了NLTK库中的Chat类。这个类需要传入一个包含正则表达式及其对应回复的pairs列表,以及一个包含反射词汇的字典reflections。这个Chat类提供了一个converse()方法,可以开始对话。如果用户输入的话匹配了某个正则表达式,Chat类会返回对应的回复。如果没有匹配到任何正则表达式,Chat类会返回默认回复。
需要注意的是,这个聊天机器人还比较简单,只能匹配一些简单的正则表达式。如果想要实现更加复杂的功能,需要进一步调整代码。
