Lỗi can not imported name trong chatbot

[hadoan]

Chào mọi người.

Mình có đoạn code Python trong việc tạo chatbot mà chạy bị lỗi… mình k hiểu lỗi này là sao và làm tnao để fix.

Mình xin cảm ơn!

from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer

chatbot = ChatBot('HA')

trainer = ListTrainer(chatbot)

trainer.train([
    "Hi, can I help you?",
    "Sure, I'd like to book a flight to Iceland.",
    "Your flight has been booked."
])

# Get a response to the input text 'I would like to book a flight.'
response = chatbot.get_response('I would like to book a flight.')

print(response)

I have fixed this problem by updating chatterbot-corpus

Thanks you!
