I was searching the internet on "How to build a Chatbot?" and I discovered ChatterBot which is a machine learning, conversational dialog engine for creating chat bots
How ChatterBot works
In this article we will see how to build a chatbot with ChatterBot in just 5 minutes.
Let's start
First Install ChatterBot
pip install ChatterBot
Create a file chat.py
#import ChatBot
from chatterbot import ChatBot
Create a new chat bot with the name of your choice(I am using "Candice").
bot = ChatBot('Candice')
Your bot is created but at this point your bot has no knowledge, for that you have to train it on some data.
Also, by default the ChatterBot library will create a sqlite database to build up statements of the chats.
Train your bot
#import ListTrainer
from chatterbot.trainers import ListTrainer
bot.set_trainer(ListTrainer)
# Training
bot.train(['What is your name?', 'My name is Candice'])
bot.train(['Who are you?', 'I am a bot, created by you' ])
Your bot is now trained on 2 statements. When you ask your bot "what is your name", it will reply back with "My name is Candice".
You can also trained it on multiple statements like
bot.train(['Do you know me?', 'Yes, you created me', 'No', 'Sahil?', 'No idea'])
As you can see it is difficult to train the bot on every single statements. So, we will use ChatterBotCorpusTrainer to train our bot on the large dataset.
from chatterbot.trainers import ChatterBotCorpusTrainer
# Create a new trainer for the chatbot
trainer = ChatterBotCorpusTrainer(bot)
# Train the chatbot based on the english corpus
trainer.train("chatterbot.corpus.english")
# Get a response to an input statement
chatbot.get_response("Hello, how are you today?")
or you can download the dataset of your language and train your bot in your language.
I downloaded the english language dataset and we can train our bot like this
for files in os.listdir('./english/'):
data=open('./english/'+files,'r').readlines()
bot.train(data)
NOTE: Make sure the dataset and the program file is on same folder, otherwise edit the path.
Chat feature
# To exit say "Bye"
while True:
# Input from user
message=input('\t\t\tYou:')
#if message is not "Bye"
if message.strip()!='Bye':
reply=bot.get_response(message)
print('Candice:',reply)
# if message is "Bye"
if message.strip()=='Bye':
print('Candice: Bye')
break
To run it, Go to terminal
python chat.py
It will train your bot first and then you can start chatting.
Source code
#import libraries
from chatterbot import ChatBot
from chatterbot.trainers import ListTrainer
import os
#Create a chatbot
bot=ChatBot('Candice')
bot.set_trainer(ListTrainer)
#training on english dataset
for files in os.listdir('./english/'):
data=open('./english/'+files,'r').readlines()
bot.train(data)
#chat feature
while True:
message=input('\t\t\tYou:')
if message.strip()!='Bye':
reply=bot.get_response(message)
print('Candice:',reply)
if message.strip()=='Bye':
print('Candice: Bye')
break

do pip install chatterbot-corpus
Then
Make the following changes to your code
remove the following lines
bot.set_trainer(ListTrainer)
bot.set_trainer(ChatterBotCorpusTrainer)
bot.train("chatterbot.corpus.english")
Add the following
trainer = ChatterBotCorpusTrainer(bot)
trainer.train('chatterbot.corpus.english')
Remove the following
training on english dataset
for files in os.listdir('./english/'):
data=open('./english/'+files,'r').readlines()
data=open('./english/'+files,'r').readlines()
trainer.train(data)
It should work now.
im not able to execute this code, cud u help me out with that..? can dm me abt it..?
What error you are facing?
cant import error
Download all the libraries.
I faced an issue when training using corpus files through "ListTrainer". seems even "categories" and "conversations" tags in yml file also get inserted into the data source.
from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
from chatterbot.trainers import ListTrainer
bot = ChatBot("Candice")
bot.set_trainer(ListTrainer)
bot.set_trainer(ChatterBotCorpusTrainer)
bot.train("chatterbot.corpus.english")
Try this
Try chatgen.ai to create chatbots. You can create click based as well as NLP Bots.
Hello
While running your code I am getting this error
AttributeError: 'ChatBot' object has no attribute 'set_trainer'
from chatterbot import ChatBot
from chatterbot.trainers import ChatterBotCorpusTrainer
from chatterbot.trainers import ListTrainer
bot = ChatBot("Candice")
bot.set_trainer(ListTrainer)
bot.set_trainer(ChatterBotCorpusTrainer)
bot.train("chatterbot.corpus.english")
Try this and if you still get the same error. You can contact me via mail: sahil.rajput.0196@gmail.com
