python Error with ChatterBot library when running simple code

First, you import the requests library, so you are able to work with and make HTTP requests. The next line begins the definition of the function get_weather() to retrieve the weather of the specified city. SpaCy’s language models are pre-trained NLP models that you can use to process statements to extract meaning. You’ll be working with the English language model, so you’ll download that. Because the industry-specific chat data in the provided WhatsApp chat export focused on houseplants, Chatpot now has some opinions on houseplant care. It’ll readily share them with you if you ask about it—or really, when you ask about anything.

In the next section, python chatbot library create a script to query the OpenWeather API for the current weather in a city. According to IBM, organizations spend over $1.3 trillion annually to address novel customer queries and chatbots can be of great help in cutting down the cost to as much as 30%. In this example, you assume that it’s called «chat.txt», and it’s located in the same directory as If you need more advanced path handling, then take a look at Python’s pathlib module. Lines 12 and 13 open the chat export file and read the data into memory. If you scroll further down the conversation file, you’ll find lines that aren’t real messages.

Regular Expression (RegEx) in Python

In this example, I am using a text file that I have taken as a sample from a website. If you’re not interested in houseplants, then pick your own chatbot idea with unique data to use for training. Repeat the process that you learned in this tutorial, but clean and use your own data for training. For example, you may notice that the first line of the provided chat export isn’t part of the conversation. Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender.

In this tutorial, we will require two libraries spacy and requests. The spacy library will help your chatbot understand the user’s sentences and the requests library will allow the chatbot to make HTTP requests. In this example, we get a response from the chatbot according to the input that we have given. Let us try to build a rather complex flask-chatbot using the chatterbot-corpus to generate a response in a flask application. With increased responses, the accuracy of the chatbot also increases.

Step 2 – Creating the chatbot function

# By epochs, we mean the number of times you repeat a training set. # Whilst training your Nural Network, you have the option of making the output verbose or simple. After connecting to the chatroom, there are several connection commands that will allow a user/bot to perform actions. Nine Reasons Why You Should Use Chatbots for Your BusinessAs a business owner Sarah was eager to use new technologies to give customers new ways of interacting with the… You can use deep learning models like BERT and other state-of-the-art deep learning models to solve classification, NER, Q&A and other NLP tasks.

  • ChatterBot is a Python library that makes it easy to generate automated responses to a user’s input.
  • Making statements based on opinion; back them up with references or personal experience.
  • Get your in-house and outsourcing specialists to work together as one team.
  • If you decide to build your own bot without using any frameworks, you need to remember that the chatbot development ecosystem is still quite new.
  • A chatbot development framework is a set of coded functions and elements that developers can use to speed up the process of building bots.
  • The DialoGPT model is pre-trained for generating text in chatbots, so it won’t work well with response generation.

The editor shows sample boilerplate code when you choose language as Python or Python2 and start coding. Chatbots relying on logic adapters work best for simple applications where there are not so many dialog variations and the conversation flow is easy to control. The logic_adapters parameter is used for setting the algorithm for choosing the response. There are five types of logic adapters represented in the ChatterBot library.


The free availability of the code leads to more transparency, but can also provide higher efficiency by collecting developers’ contributions relating to any changes. 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.

Which IDE is the best for Python AI?

  • IDLE. IDLE (Integrated Development and Learning Environment) is a default editor that accompanies Python.
  • PyCharm. PyCharm is a widely used Python IDE created by JetBrains.
  • Visual Studio Code. Visual Studio Code is an open-source (and free) IDE created by Microsoft.
  • Sublime Text 3.
  • Atom.
  • Jupyter.
  • Spyder.
  • PyDev.

The architecture is based on two neural networks that process data in parallel while communicating closely with each other. Apriorit offers robust driver development and system programming services, delivering secure and reliable kernel and driver solutions for all kinds of systems and devices. We can implement critical changes at the operating system level to improve the flexibility, integration, and security of your solution. Leverage Apriorit’s expertise to deliver efficient and competitive IT solutions. We offer a wide range of services, from research and discovery to software development, testing, and project management. Because neural networks can only understand numerical values, we must first process our data so that a neural network can understand what we are doing.

Next Steps

You can run more than one training session, so in lines 13 to 16, you add another statement and another reply to your chatbot’s database. After importing ChatBot in line 3, you create an instance of ChatBot in line 5. The only required argument is a name, and you call this one «Chatpot». No, that’s not a typo—you’ll actually build a chatty flowerpot chatbot in this tutorial!

Human in the Loop For Enterprise ChatbotsIn the world of chatbots “human in the loop” means the ability of human agents to monitor and manually take charge of… Bottender lets you create apps on every channel and never compromise on your users’ experience. You can apply progressive enhancement or graceful degradation strategy to your building blocks. Claudia Bot Builder simplifies messaging workflows and converts incoming messages from all the supported platforms into a common format, so you can handle it easily. It also automatically packages text responses into the right format for the requesting bot engine, so you don’t have to worry about formatting results for simple responses. With this software, you can build your first conversational application easily without having any previous experience with a coding language.

By following this article’s explanation of ChatBots, their utility in business, and how to implement them, we may create a primitive Chatbot using Python and the Chatterbot Library. Anyone interested in gaining a better knowledge of conversational artificial intelligence will benefit greatly from this article. Virtual assistants seem like something out of a science fiction movie. Thanks to the implementation of chatbot applications, we are able to revolutionize the way humans and machines communicate with each other.

Is Python good for chatbots?

Yes, Python could be a great choice for building chatbots because of its Chatterbox library, which is developed using machine learning, with a built-in training engine and conversational dialogue flow. The user's response will be used to automatically train the bot that was constructed using this library.

Thankfully, nowadays, you can use a framework to have the groundwork done for you. This way, even beginner developers can create custom-made bots for themselves as well as clients. Chatbot platforms are usually ready-to-use solutions with visual builders. They are powered and hosted by third parties and require no coding skills. When it comes to chatbot frameworks, they give you more flexibility in developing your bots.
