How to Make a Chatbot in Python

It also allows a basic configuration (description, profile photo, inline support, etc.). The context is the first message we send to the model before it can talk to the user. In it, we will indicate how the model should behave and the tone of the response.

That way, messages sent within a certain time period could be considered a single conversation. I am a full-stack software, and machine learning solutions developer, with experience architecting solutions in complex data & event driven environments, for domain specific use cases. When it gets a response, the response is added to a response channel and the chat history is updated.


Our code for the Python Chatbot will then allow the machine to pick one of the responses corresponding to that tag and submit it as output. 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.

The next step is to instantiate the Chat() function containing the pairs and reflections. If a match is found, the current intent gets selected and is used as the key to the responses dictionary to select the correct response. Here, we first defined a list of words list_words that we will be using as our keywords. We used WordNet to expand our initial list with synonyms of the keywords. Once we run the above command, we should expect an output similar to the one shown below.

Update to include the create_rejson_connection method. Also, update the .env file with the authentication data, and ensure rejson is installed. To handle chat history, we need to fall back to our JSON database. We’ll use the token to get the last chat data, and then when we get the response, append the response to the JSON database. But remember that as the number of tokens we send to the model increases, the processing gets more expensive, and the response time is also longer. The GPT class is initialized with the Huggingface model url, authentication header, and predefined payload.

Next, in Postman, when you send a POST request to create a new token, you will get a structured response like the one below. You can also check Redis Insight to see your chat data stored with the token as a JSON key and the data as a value. The messages sent and received within this chat session are stored with a Message class which creates a chat id on the fly using uuid4. The only data we need to provide when initializing this Message class is the message text. In Redis Insight, you will see a new mesage_channel created and a time-stamped queue filled with the messages sent from the client.

Step-3: Reading the JSON file

The conversation isn’t yet fluent enough that you’d like to go on a second date, but there’s additional context that you didn’t have before! When you train your chatbot with more data, it’ll get better at responding to user inputs. You can build an industry-specific chatbot by training it with relevant data. Additionally, the chatbot will remember user responses and continue building its internal graph structure to improve the responses that it can give. Next, we await new messages from the message_channel by calling our consume_stream method.

A rule-based chatbot is one that relies on a set of rules or a decision tree to determine how to respond to a user’s input. The chatbot will go through the rules one by one until it finds a rule that applies to the user’s input. As we saw, building a rule-based chatbot is a laborious process. In a business environment, a chatbot could be required to have a lot more intent depending on the tasks it is supposed to undertake. This is a fail-safe response in case the chatbot is unable to extract any relevant keywords from the user input.

The Whys and Hows of Predictive Modeling-II

After adding an intent, you don’t need to add agent responses in the Responses section. Since we are using Flask for the same, you need to enable webhook for this intent. The webhook will help us transfer data and responses between Dialogflow and Flask. Dialogflow provides webhook services via Dialogflow Fulfillment. I preferred using infinite while loop so that it repeats asking the user for an input. In this Telegram bot tutorial, I’m going to create a Python chatbot with the help of pyTelegramBotApi library.

In order for this to work, you’ll need to provide your chatbot with a list of responses. The command ‘logic_adapters’ provides the list of resources that will be used to train the chatbot. The last process of building a chatbot in Python involves training it further. You can also do it by specifying the lists of strings that can be utilized for training the Python chatbot, and choosing the best match for each argument.

Step 3: Export a WhatsApp Chat

Use Flask to create a web interface for your chatbot, allowing users to interact with it through a browser. Use the ChatterBotCorpusTrainer to train your chatbot using an English language corpus. Import ChatterBot and its corpus trainer to set up and train the chatbot. Understanding the types of chatbots and their uses helps you determine the best fit for your needs. The choice ultimately depends on your chatbot’s purpose, the complexity of tasks it needs to perform, and the resources at your disposal. The Chatbot Python adheres to predefined guidelines when it comprehends user questions and provides an answer.

  • In lines 9 to 12, you set up the first training round, where you pass a list of two strings to trainer.train().
  • Next create an environment file by running touch .env in the terminal.
  • Now it’s time to import the necessary libraries and report the value of the key that we just obtained from OpenAI.

Chatbots can help you perform many tasks and increase your productivity. There are two classes that are required, ChatBot and ListTrainer from the ChatterBot library. One is to use the built-in module called threading, which allows you to build a chatbox by creating a new thread for each user. Another way is to use the ‘tkinter’ module, which is a GUI toolkit that allows you to make a chatbox by creating a new window for each user. We use the RegEx Search function to search the user input for keywords stored in the value field of the keywords_dict dictionary. If you recall, the values in the keywords_dict dictionary were formatted with special sequences of meta-characters.

We will use WebSockets to ensure bi-directional communication between the client and server so that we can send responses to the user in real-time. To set up the project structure, create a folder namedfullstack-ai-chatbot. Then create two folders within the project called client and server. The server will hold the code for the backend, while the client will hold the code for the frontend. Then we will pass conversation data to trainer.train() function. Its knowledge is limited to the stuff similar to what it has learned.
