Xorbits

This notebook shows how to use agents to interact with Xorbits Pandas dataframe and Xorbits Numpy ndarray. It is mostly optimized for question answering.

NOTE: this agent calls the Python agent under the hood, which executes LLM generated Python code - this can be bad if the LLM generated Python code is harmful. Use cautiously.

Pandas examples​

import xorbits.pandas as pd
from langchain_experimental.agents.agent_toolkits import create_xorbits_agent
from langchain_openai import OpenAI
data = pd.read_csv("titanic.csv")
agent = create_xorbits_agent(OpenAI(temperature=0), data, verbose=True)

agent.run("How many rows and columns are there?")


> Entering new  chain...
Thought: I need to count the number of rows and columns
Action: python_repl_ast

Observation: (891, 12)
Thought: I now know the final answer
Final Answer: There are 891 rows and 12 columns.
