Building an AI Chatbot with Essential Python Libraries

On top of this, the machine learning algorithms make it easier for the bot to improve on its own using the user’s input. 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. In addition to this, Python also has a more sophisticated set of machine-learning capabilities with an advantage of choosing from different rich interfaces and documentation. Without this flexibility, the chatbot’s application and functionality will be widely constrained. By following these steps, you’ll have a functional Python AI chatbot that you can integrate into a web application.

Above we created the AIML file that only handles one pattern, load aiml b. When we enter that command

to the bot, it will try to load basic_chat.aiml. This is a fail-safe response in case the chatbot is unable to extract any relevant keywords from the user input.

Step 6: Train Your Chatbot with Custom Data

This has been achieved by iterating over each pattern using a nested for loop and tokenizing it using nltk.word_tokenize. The words have been stored in data_X and the corresponding tag to it has been stored in data_Y. Access to a curated library of 250+ end-to-end industry projects with solution code, videos and tech support. Okay, so now that you have a rough idea of the deep learning algorithm, it is time that you plunge into the pool of mathematics related to this algorithm. According to a Uberall report, 80 % of customers have had a positive experience using a chatbot. Remember, overcoming these challenges is part of the journey of developing a successful chatbot.

We covered several steps in the whole article for creating a chatbot with ChatGPT API using Python which would definitely help you in successfully achieving the chatbot creation in Gradio. There are countless uses of Chat GPT of which some we are aware and some we aren’t. Corpus can be created or designed either manually or by using the accumulated data over time through the chatbot.

Build Chatbots with Python

In this tutorial, we have built a simple chatbot using Python and TensorFlow. We started by gathering and preprocessing data, then we built a neural network model using the Keras Sequential API. We then created a simple command-line interface for the chatbot and tested it with some example conversations.

Note that saving

the brain file does not save all the session values. When you start to have a lot of AIML files, it can take a long time to learn. After the bot learns all the AIML files

it can save its brain directly to a file which will drastically speed up load times

on subsequent runs. It can be fun to write your own AIML files, but it can be a lot of work.

If you created your OpenAI account earlier, you may have free credit worth $18. After the free credit is exhausted, you will have to pay for the API access. In this article, we decided to focus on creating smart bots with Python, as this language is quite popular for building AI solutions. We’ll make sure to cover other programming languages in our future posts.

Note that to access the message array, we need to provide .messages as an argument to the Path. If your message data has a different/nested structure, just provide the path to the array you want to append the new data to. For every new input we send to the model, there is no way for the model to remember the conversation history. This is important if we want to hold context in the conversation. In the next section, we will focus on communicating with the AI model and handling the data transfer between client, server, worker, and the external API. In order to use Redis JSON’s ability to store our chat history, we need to install rejson provided by Redis labs.

We’ll also use the requests library to send requests to the Huggingface inference API. During the trip between the producer and the consumer, the client can send multiple messages, and these messages will be queued up and responded to in order. Once you have set up your Redis database, create a new folder in the project root (outside the server folder) named worker. Redis is an open source in-memory data store that you can use as a database, cache, message broker, and streaming engine. It supports a number of data structures and is a perfect solution for distributed applications with real-time capabilities. In the next part of this tutorial, we will focus on handling the state of our application and passing data between client and server.
