Chatterbot: Is it possible to save a pre-trained chatbot?

[NavyaZaveri]

Title, really. I was wondering if it's possible to save an existing model so that I don't have to train it every time I re-run my script.

I've looked at the docs, and the closest I found was the method export_for_training; but that only exports training data, not the chatbot itself.

Is there a mechanism that saves a chatbot?

ChatterBot instances are designed to be stateless. Everything that they learn is stored in a chat bot's connected database.

You shouldn't need to re-train your chat bot each time the script is run because the training data is persisted.

So, to answer the question, there is no method that allows a chat bot to be "saved", but if yo want to create a database backup then you can easily restore it to another chat bot's database.

As master @gunthercox said, the trained data is persist, so we can re-use whenever you required.

some workaround or an actual answer i am not sure, you could split your bot program into two phase one for train, one for bot.

For example

train.py

# -*- coding: utf-8 -*-
from chatterbot import ChatBot

# Create a new chat bot named Charlie
chatbot = ChatBot(
    'Charlie',
    trainer='chatterbot.trainers.ListTrainer'
)

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

bot.py

```Python
# -*- coding: utf-8 -*-
from chatterbot import ChatBot

# Create a new chat bot named Charlie
chatbot = ChatBot(
    'Charlie',
    trainer='chatterbot.trainers.ListTrainer'
)
# Get a response to the input text 'How are you?'
response = chatbot.get_response('I would like to book a flight.')

print(response)
