The only required argument is a name, and you call this one "Chatpot". To get started with your chatbot project, create and activate a virtual environment, then install chatterbot and pytz:ġ # bot.py 2 3 from chatterbot import ChatBot 4 5 chatbot = ChatBot ( "Chatpot" ) 6 7 exit_conditions = ( ":q", "quit", "exit" ) 8 while True : 9 query = input ( "> " ) 10 if query in exit_conditions : 11 break 12 else : 13 print ( f "□ " )Īfter importing ChatBot in line 3, you create an instance of ChatBot in line 5. You’ll also create a working command-line chatbot that can reply to you-but it won’t have very interesting replies for you yet. In this step, you’ll set up a virtual environment and install the necessary dependencies. Step 1: Create a Chatbot Using Python ChatterBot You can always stop and review the resources linked here if you get stuck. If you don’t have all of the prerequisite knowledge before starting this tutorial, that’s okay! In fact, you might learn more by going ahead and getting started. If you’re comfortable with these concepts, then you’ll probably be comfortable writing the code for this tutorial. Python comprehensions and generator expressions.Substring checks and substring replacement. You’ll touch on a handful of Python concepts while working through the tutorial: If you’ve installed the right Python version for your operating system, then you’re ready to get started. The chatbot was built and tested with Python 3.10.7 but should also run with older Python versions. You can run the project with a variety of Python versions. Therefore, you’ll either fetch the conversation history of one of your WhatsApp chats or use the provided chat.txt file that you can download here: The more plentiful and high-quality your training data is, the better your chatbot’s responses will be. Next, you’ll learn how you can train such a chatbot and check on the slightly improved results. You’ll also notice how small the vocabulary of an untrained chatbot is. In this tutorial, you’ll start with an untrained chatbot that’ll showcase how quickly you can create an interactive chatbot using Python’s ChatterBot. You’ll find more information about installing ChatterBot in step one. Instead, you’ll use a specific pinned version of the library, as distributed on PyPI. To get started, however, you won’t use a fork. A fork might also come with additional installation instructions. There are multiple forks of the project that implement fixes and updates to the existing codebase, but you’ll have to personally pick the fork that implements the solution you’re looking for and then install it directly from GitHub. Overall, in this tutorial, you’ll quickly run through the basics of creating a chatbot with ChatterBot and learn how Python allows you to get fun and useful results without needing to write a lot of code.Īttention: While ChatterBot is still a popular open source solution for building a chatbot in Python, it hasn’t been actively maintained for a while and has therefore accumulated a significant number of issues. You’ll also learn how ChatterBot stores your training data, and you’ll find suggestions and pointers for next steps, so you can start collecting real user data and let the chatbot learn from it. Retrain the chatbot with industry-specific data.Perform data cleaning on the chat export using regular expressions.Train the chatbot to customize its responses.Build a command-line chatbot with ChatterBot.You can apply a similar process to train your bot from different conversational data in any domain-specific topic. You’ll do this by preparing WhatsApp chat data to train the chatbot. To simulate a real-world process that you might go through to create an industry-relevant chatbot, you’ll learn how to customize the chatbot’s responses. The quality and preparation of your training data will make a big difference in your chatbot’s performance. You’ll get the basic chatbot up and running right away in step one, but the most interesting part is the learning phase, when you get to train your chatbot. When you understand the basics of the ChatterBot library, you can build and train a self-learning chatbot with just a few lines of Python code. Chatbots can provide real-time customer support and are therefore a valuable asset in many industries.
