How to build a Chatbot with ChatGPT API and a Conversational Memory in Python by Avra

Depending on the amount and quality of your training data, your chatbot might already be more or less useful. You refactor your code by moving the function calls from the name-main idiom into a dedicated function, clean_corpus(), that you define toward the top of the file. In line 6, you replace “chat.txt” with the parameter chat_export_file to make it more general. The clean_corpus() function returns the cleaned corpus, which you can use to train your chatbot.

The first thing we’re going to do is to train the Chatbot model. In order to do that, create a file named ‘intense.json’ in which we’ll write all the intents, tags and words or phrases our Chatbot would be responding to. In this article, you’ll learn how to deploy a Chatbot using Tensorflow. A Chatbot is basically a bot (a program) that talks and responds to various questions just like a human would. Let’s create a file, import all the necessary libraries, config files and the previously created If some of the libraries are absent, install them via pip.

Memory in conversations with OpenAI.

In simpler words, you wouldn’t want your chatbot to always listen in and partake in every single conversation. Hence, we create a function that allows the chatbot to recognize its name and respond to any speech that follows after its name is called. As the topic suggests we are here to help you have a conversation with your AI today. To have a conversation with your AI, you need a few pre-trained tools which can help you build an AI chatbot system.

  • There are a lot of options when it comes to where you can deploy your chatbot, and one of the most common uses are social media platforms, as most people use them on a regular basis.
  • The bot uses pattern matching to classify the text and produce a response for the customers.
  • For this, we are using OpenAI’s latest “gpt-3.5-turbo” model, which powers GPT-3.5.
  • However, if you bump into any issues, then you can try to install Python 3.7.9, for example using pyenv.
  • We won’t require 6000 lines of code to create a chatbot but just a six-letter word “Python” is enough.
  • The chatbot picked the greeting from the first user input (‘Hi’) and responded according to the matched intent.

The model builds the sentence by figuring out which word it should use, choosing it from a list of words that has a percentage of chances of appearing. If we are familiar with ChatGPT, we can see that it keeps a memory of the conversation. Well, this is so because the memory is being maintained by the interface, not the model. In our case, we will pass the list of all messages generated, jointly with the context, in each call to ChatCompletion.create. To send text, containing our part of the dialog to the model, we must use the ChatCompletion.create function, indicating, at least, the model to use and a list of messages.

Step-6: Building the Neural Network Model

We are not going to program, we are going to try to make it behave as we want by giving it some instructions. At the same time, we must also provide it with enough information so that it can do its job properly informed. Each message in the list contains a role and the text we want to send to the model. Algorithms reduce the number of classifiers and create a more manageable structure. Some of the examples are naïve Bayes, decision trees, support vector machines, Recurrent Neural Networks (RNN), Markov chains, etc. The bot uses pattern matching to classify the text and produce a response for the customers.

Once this process is complete, we can go for lemmatization to transform a word into its lemma form. Then it generates a pickle file in order to store the objects of Python that are utilized to predict the responses of the bot. Over time, as the chatbot indulges in more communications, the precision of reply progresses. NLP technologies have made it possible for machines to intelligently decipher human text and actually respond to it as well.

Set Up a Meeting

Every time a chatbot gets the input from the user, it saves the input and the response which helps the chatbot with no initial knowledge to evolve using the collected responses. In such a situation, rule-based chatbots become very impractical as maintaining a rule base would become extremely complex. In addition, the chatbot would severely be limited in terms of its conversational capabilities as it is near impossible to describe exactly how a user will interact with the bot. This is a fail-safe response in case the chatbot is unable to extract any relevant keywords from the user input. The chatbot will automatically pull their synonyms and add them to the keywords dictionary. You can also edit list_syn directly if you want to add specific words or phrases that you know your users will use.

Can I do AI with Python?

Python is the major code language for AI and ML. It surpasses Java in popularity and has many advantages, such as a great library ecosystem, Good visualization options, A low entry barrier, Community support, Flexibility, Readability, and Platform independence.

Here, click on “Create new secret key” and copy the API key. Do note that you can’t copy or view the entire API key later on. So it’s strongly recommended to copy and paste the API key to a Notepad file immediately.

You now collect the return value of the first function call in the variable message_corpus, then use it as an argument to remove_non_message_text(). You save the result of that function call to cleaned_corpus and print that value to your console on line 14. Find the file that you saved, and download it to your machine.

These language models are based on the Generative Pre-trained Transformer 3 (GPT-3) architecture, which is currently one of the most advanced language models available. Chatbots are a powerful tool for engaging with users and providing them with personalized experiences. They can be used in a variety of settings, from customer support to e-commerce to education. We will be using openai to access the text generation API and streamlit to create the chatbot interface.

Natural Language Processing using NLTK (Python)

That way, messages sent within a certain time period could be considered a single conversation. ChatterBot uses complete lines as messages when a chatbot replies to a user message. In the case of this chat export, it would therefore include all the message metadata. That means your friendly pot would be studying the dates, times, and usernames!

Can I make my own AI with Python?

Why Python Is Best For AI. We have seen a lot of people asking which programming language is best for building AI. Python being a general-purpose language made its way to the most complex technologies such as machine learning, deep learning, artificial intelligence and so on.
