What is HuggingChat?

Hugging Chat is an open-source AI-powered chatbot that has been designed to revolutionize the way we interact with technology. With its advanced natural language processing capabilities, Hugging Chat offers a seamless and intuitive conversational experience that feels incredibly human-like. One of its key strengths lies in its ability to understand and generate contextually relevant responses, ensuring that conversations flow naturally and intelligently. Hugging Chat’s underlying technology is based on large language models, which have been trained on vast amounts of text data, enabling it to grasp a wide range of topics and provide informative and engaging responses.


It can assist users in generating code snippets based on their prompts, making it an invaluable tool for developers and programmers. Whether it’s providing code examples, explaining syntax, or offering solutions to various challenges, Hugging Chat’s code generation feature enhances its versatility and utility. Additionally, Hugging Chat prioritizes user privacy and data security, ensuring confidential and secure conversations. It adheres to ethical AI practices, refraining from storing user information or conversations, thus providing users with peace of mind and control over their personal data. 

Unofficial HuggingChat Python API is available here.

What is Pipeline?

A pipeline refers to a sequence of data processing components arranged in a specific order. Each component in the pipeline performs a particular task on the data, and the output of one component becomes the input of the next. Pipelines are commonly used to streamline the machine learning workflow, allowing for efficient data preprocessing, feature engineering, model training, and evaluation. By organizing these tasks into a pipeline, it becomes easier to manage, reproduce, and deploy machine learning models.

The pipeline is as follows:

  • Text Query: User queries the system with all the requirements specified
  • Request: Query is restructured and the request is sent to HuggingChat API(unofficial)
  • HuggingChatAPI: Processes the query and generates relevant code
  • Response: Generated code is received by user as response
  • Execution: Resultant Python code is executed to get desired output

Step-by Step Implementation of Query2Model

Let us now look into the step by step implementation of Query2Model:

Step1. Import Libraries

Let us start by importing the following libraries:

  • sklearn: versatile machine learning library in Python, offering a comprehensive suite of tools for data preprocessing, model training, evaluation, and deployment.
  • pandas: powerful data manipulation and analysis library in Python, designed to simplify the handling of data efficiently.
  • hugchat: unofficial HuggingChat Python API, extensible for chatbots etc.
!pip install  hugchat
import sklearn
import pandas as pd
from hugchat import hugchat
from hugchat.login import Login

Step2. Defining Query2Model Class

Formatting prompt is used to structure the output in desired format. It consists of several guidelines such as printing results if needed, including indentations, ensuring error-free code, etc., to ensure the output from the chatbot contains only executable code without errors when passed to the exec() function.

#formatting_prompt is to ensure that the response contains only the required code
formatting_prompt = """Error-free code
Store the variable names in variables for future reference.
Print the result if required
Code should be well indented with spaces, etc., should not contain importing libraries, comments.
No loops.
Output should be executable without errors when it is passed to exec() function"""

The Query2Model class is a tool for executing user queries within a specific environment. It requires the user’s email and password for authentication, sets a cookie storage directory, and initializes a Login object. After successful authentication, it retrieves and saves cookies, initializing a ChatBot object for interaction. The execute_query() method executes user queries, returning the result as a string.

class Query2Model:
    def __init__(self, email, password): = email
        self.password = password
        self.cookie_path_dir = "./cookies/" 
        self.sign = Login(EMAIL, PASSWD)
        self.cookies = sign.login(cookie_dir_path=cookie_path_dir, save_cookies=True)
        self.chatbot = hugchat.ChatBot(cookies=cookies.get_dict())

    # function to execute the user's query
    def execute_query(self, query):
        query_result =
        return str(query_result)

User needs to provide the login credentials of HuggingFace account for authentication

user = Query2Model(email="email", password="password")

Step3. Data Preparation and Preprocessing

Query includes path to the dataset(here the dataset is present in current working directory), the variable to store it upon reading, and to display the first 5 rows.

query= r"""Read the csv file at path: iris.csv into df variable and display first 5 rows"""
output_code= user.execute_query( query )
print(output_code, sep="\n")

Separating the input features(X) and label(y) into separate dataframes. Features includes sepal length& width, petal length& width which represent the characteristics of iris flower. Label denotes which species the flower belongs to.

query= r"""Store 'SepalLengthCm', 'SepalWidthCm', 'PetalLengthCm', 'PetalWidthCm' in X
       and 'Species' in y"""
output_code= user.execute_query( query )
print(output_code, sep="\n")

Dividing 80% of data for training and 20% of data for testing with a random state of 111 

query= r"""Divide X, y for training and testing with 80-20% with random_state=111"""
output_code= user.execute_query( query )
print(output_code, sep="\n")

Applying standard scaler technique to normalize the data. It transforms the data by removing the mean and scaling it to unit variance, ensuring that each feature has a mean of 0 and a standard deviation of 1.

query= r"""Apply standard scaler"""
output_code= user.execute_query( query )
print(output_code, sep="\n")

Step4. Model Training and Evaluation

Query contains instructions to train a random forest classifier, display it’s accuracy, and finally to save the trained model for futuristic tasks. As any hyperparameters are not specified in the query, it considers default ones.

Random Forest: Random forest algorithm operates by constructing multiple decision trees during training and outputs the mode of the classes or mean prediction of the individual trees for regression tasks.

query= r"""Train a random forest classifier, print the accuracy, and save in .pkl"""
output_code= user.execute_query( query )
print(output_code, sep="\n")

After successfully training the model, we perform querying to check the output based on provided input features.

query= r"""Load the model, and predict ouput for SepalLength= 5.1, SepalWidth= 3.5, PetalLength= 1.4, and PetalWidth= 0.2"""
output_code= user.execute_query( query )
print(output_code, sep="\n")
