pandasai 0.2.14

Pandas AI is a Python library that integrates generative artificial intelligence capabilities into Pandas, making dataframes conversational.

PandasAI 🐼

Pandas AI is a Python library that adds generative artificial intelligence capabilities to Pandas, the popular data analysis and manipulation tool. It is designed to be used in conjunction with Pandas, and is not a replacement for it.

Demo

Try out PandasAI in your browser:

Installation

pip install pandasai

Usage

Disclaimer: GDP data was collected from this source, published by World Development Indicators - World Bank (2022.05.26) and collected at National accounts data - World Bank / OECD. It relates to the year of 2020. Happiness indexes were extracted from the World Happiness Report. Another useful link.

PandasAI is designed to be used in conjunction with pandas. It makes Pandas conversational, allowing you to ask questions about your data and get answers back, in the form of pandas DataFrames. For example, you can ask PandasAI to find all the rows in a DataFrame where the value of a column is greater than 5, and it will return a DataFrame containing only those rows:

import pandas as pd
from pandasai import PandasAI

# Sample DataFrame
df = pd.DataFrame({
    "country": ["United States", "United Kingdom", "France", "Germany", "Italy", "Spain", "Canada", "Australia", "Japan", "China"],
    "gdp": [19294482071552, 2891615567872, 2411255037952, 3435817336832, 1745433788416, 1181205135360, 1607402389504, 1490967855104, 4380756541440, 14631844184064],
    "happiness_index": [6.94, 7.16, 6.66, 7.07, 6.38, 6.4, 7.23, 7.22, 5.87, 5.12]
})

# Instantiate a LLM
from pandasai.llm.openai import OpenAI
llm = OpenAI(api_token="YOUR_API_TOKEN")

pandas_ai = PandasAI(llm, conversational=False)
pandas_ai(df, prompt='Which are the 5 happiest countries?')

The above code will return the following:

6            Canada
7         Australia
1    United Kingdom
3           Germany
0     United States
Name: country, dtype: object

Of course, you can also ask PandasAI to perform more complex queries. For example, you can ask PandasAI to find the sum of the GDPs of the 2 unhappiest countries:

pandas_ai(df, prompt='What is the sum of the GDPs of the 2 unhappiest countries?')

The above code will return the following:

19012600725504

You can also ask PandasAI to draw a graph:

pandas_ai(
    df,
    "Plot the histogram of countries showing for each the gpd, using different colors for each bar",
)

You can find more examples in the examples directory.

Command-Line Tool

Pai is the command line tool designed to provide a convenient way to interact with PandasAI through a command line interface (CLI).

pai [OPTIONS]

Options:

• -d, --dataset: The file path to the dataset.
• -t, --token: Your HuggingFace or OpenAI API token, if no token provided pai will pull from the .env file.
• -m, --model: Choice of LLM, either openai, open-assistant, or starcoder.
• -p, --prompt: Prompt that PandasAI will run.

To view a full list of available options and their descriptions, run the following command:

pai --help

For example,

pai -d "~/pandasai/example/data/Loan payments data.csv" -m "openai" -p "How many loans are from men and have been paid off?"

Should result in the same output as the from_csv.py example.

Privacy & Security

In order to generate the Python code to run, we take the dataframe head, we randomize it (using random generation for sensitive data and shuffling for non-sensitive data) and send just the head.

Also, if you want to enforce further your privacy you can instantiate PandasAI with enforce_privacy = True which will not send the head (but just column names) to the LLM.

Environment Variables

In order to set the API key for the LLM (Hugging Face Hub, OpenAI), you need to set the appropriate environment variables. You can do this by copying the .env.example file to .env:

cp .env.example .env

Then, edit the .env file and set the appropriate values.

As an alternative, you can also pass the environment variables directly to the constructor of the LLM:

# OpenAI
llm = OpenAI(api_token="YOUR_API_KEY")

# Starcoder
llm = Starcoder(api_token="YOUR_HF_API_KEY")
