Chatterbot-Installation unter FreeBSD 12

Unter FreeBSD ist die Installation des Chatterbots ein wenig diffiziler. Man kriegst aber trotzdem hin. Ein Installationsprotokoll.


Als Test-Program für die Installation wird charlie.py verwendet. Es wird Python 3.7 verwenden, das unter /usr/local/bin zu finden ist


Die Dokumentation ist hier zu finden: https://chatterbot.readthedocs.io/en/stable/examples.html#simple-example


Test-Programm charlie.py

#!/usr/local/bin/python3.7
from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer

# Create a new chat bot named Charlie
chatbot = ChatBot('Charlie')

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)
