CSV Agent

This notebook shows how to use agents to interact with a csv. It is mostly optimized for question answering.

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

from langchain.agents.agent_types import AgentType

Using ZERO_SHOT_REACT_DESCRIPTION

This shows how to initialize the agent using the ZERO_SHOT_REACT_DESCRIPTION agent type. Note that this is an alternative to the above.

In [9]:

agent = create_csv_agent(
    OpenAI(temperature=0),
    "titanic.csv",
    verbose=True,
    agent_type=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
)

Using OpenAI Functions

This shows how to initialize the agent using the OPENAI_FUNCTIONS agent type. Note that this is an alternative to the above.

In [3]:

agent = create_csv_agent(
    ChatOpenAI(temperature=0, model="gpt-3.5-turbo-0613"),
    "titanic.csv",
    verbose=True,
    agent_type=AgentType.OPENAI_FUNCTIONS,
)

In [4]:

agent.run("how many rows are there?")

Out [4]:

Error in on_chain_start callback: 'name'


Invoking: `python_repl_ast` with `df.shape[0]`


891There are 891 rows in the dataframe.

> Finished chain.

'There are 891 rows in the dataframe.'

In [5]:

agent.run("how many people have more than 3 siblings")

Out [5]:

Error in on_chain_start callback: 'name'


Invoking: `python_repl_ast` with `df[df['SibSp'] > 3]['PassengerId'].count()`


30There are 30 people in the dataframe who have more than 3 siblings.

> Finished chain.

'There are 30 people in the dataframe who have more than 3 siblings.'

In [6]:

agent.run("whats the square root of the average age?")

Out [6]:

Error in on_chain_start callback: 'name'


Invoking: `python_repl_ast` with `import pandas as pd
import math

# Create a dataframe
data = {'Age': [22, 38, 26, 35, 35]}
df = pd.DataFrame(data)

# Calculate the average age
average_age = df['Age'].mean()

# Calculate the square root of the average age
square_root = math.sqrt(average_age)

square_root`


5.585696017507576The square root of the average age is approximately 5.59.

> Finished chain.

'The square root of the average age is approximately 5.59.'

Multi CSV Example

This next part shows how the agent can interact with multiple csv files passed in as a list.

In [8]:

agent = create_csv_agent(
    ChatOpenAI(temperature=0, model="gpt-3.5-turbo-0613"),
    ["titanic.csv", "titanic_age_fillna.csv"],
    verbose=True,
    agent_type=AgentType.OPENAI_FUNCTIONS,
)
agent.run("how many rows in the age column are different between the two dfs?")

Out [8]:

Error in on_chain_start callback: 'name'


Invoking: `python_repl_ast` with `df1['Age'].nunique() - df2['Age'].nunique()`


-1There is 1 row in the age column that is different between the two dataframes.

> Finished chain.

'There is 1 row in the age column that is different between the two dataframes.'
