google-pandas-agent 1.0.3

Google‑native alternative to LangChain's create_pandas_dataframe_agent

Google Pandas Agent

A Google-native alternative to LangChain's create_pandas_dataframe_agent, powered by Google's Gemini models and LangGraph.

Features

• Query pandas DataFrames using natural language
• Powered by Google's Gemini models
• Simple, intuitive interface
• Type-safe implementation
• Comprehensive error handling
• Support for multiple DataFrames

Installation

pip install google-pandas-agent

Requirements

• Python >= 3.10
• pandas >= 2.2
• google-generativeai >= 0.8.5
• langgraph >= 0.3.21

Quick Start

import pandas as pd
import google.generativeai as genai
from google_pandas_agent import create_pandas_dataframe_agent

# Initialize Gemini
genai.configure(api_key='your-api-key')  # Get your API key from Google Cloud Console
model = genai.GenerativeModel('gemini-pro')

# Create a sample DataFrame
df = pd.DataFrame({
    'Name': ['Alice', 'Bob', 'Charlie'],
    'Age': [25, 30, 35],
    'City': ['New York', 'London', 'Paris']
})

# Create the agent
agent = create_pandas_dataframe_agent(model, df)

# Ask questions about your data
response = agent.chat("What is the average age?")
print(response)

# You can also use multiple DataFrames
df2 = pd.DataFrame({
    'City': ['New York', 'London', 'Paris'],
    'Country': ['USA', 'UK', 'France']
})

agent = create_pandas_dataframe_agent(model, [df, df2])
response = agent.chat("Show me people's names along with their countries")
print(response)

API Reference

create_pandas_dataframe_agent

def create_pandas_dataframe_agent(
    llm: genai.GenerativeModel,
    df: Union[pd.DataFrame, List[pd.DataFrame]],
    *,
    verbose: bool = False,
    allow_dangerous_code: bool = False,
    **kwargs,
) -> AgentExecutor

Creates an agent that can answer questions about pandas DataFrames.

Parameters

• llm: A Gemini model instance (must be initialized with genai.GenerativeModel)
• df: A pandas DataFrame or list of DataFrames
• verbose: Enable verbose output (default: False)
• allow_dangerous_code: Allow potentially unsafe imports in the Python REPL (default: False)
• **kwargs: Additional arguments passed to the executor

Returns

An AgentExecutor instance that can process natural language queries about the DataFrame(s)

AgentExecutor

The main class for executing queries against DataFrames.

Methods

• chat(question: str) -> str: Process a natural language query and return the response
• run(question: str) -> str: Alias for chat()
• invoke(state: dict) -> dict: Advanced method for custom state handling

Common Issues and Solutions

1. Import Error: If you get an error about missing dependencies, make sure you have all required packages installed:

   pip install "google-pandas-agent[all]"
   

2. API Key Error: Make sure to configure your Google API key before creating the model:

   genai.configure(api_key='your-api-key')
   

3. Model Error: Ensure you're using the correct model name ('gemini-pro'):

   model = genai.GenerativeModel('gemini-pro')
