Financial Analysis with Langchain and CrewAI Agents

Community Article Published June 30, 2024

This weekend I am experimenting how two frameworks that overlap compare with each other, langchain and crewAI.

For the most part this is not a fair experiment, since I'm using Cohere's cmd r for langchain and GPT 3.5 for crewAI and IMO cmd R is better at understanding and following instructions. I also don't have much experience with crewai and this is my attempt to learn it

How to Become an Expert at Something (Attempting to Be an Expert)

  1. Iteratively take on concrete projects and accomplish them in depth, learning "on demand" (i.e., don't learn from the bottom up).
  2. Teach/Summarize everything you learn in your own words.
  3. Only compare yourself to your younger self (comparing to others may discourage you).

Following a guide on cohere's website I chose to use their model CMD-R (It's free unlike others)

COHERE_API_KEY = os.environ["COHERE_API_KEY"] 
CHAT_URL= "https://api.cohere.ai/v1/chat"
COHERE_MODEL = 'command-r-plus'

Define Python Tool

Here we define the python tool using langchain's PythonREPL. We also define functions_map that will later be used by the Cohere Agent to correctly map function name to the actual function. Lastly, we define the tools that will be passed in the Cohere API.

python_repl = PythonREPL()
python_tool = Tool(
    name="python_repl",

QnA over Single Table

In the example below, we show how the python tool can be used to load a dataframe and extract information from it. To do this successfully we need to:

  1. pass the file name to the preamble so the model knows how to load the dataframe
  2. pass a preview of the dataframe in the preamble so the model knows which columns/rows to query

We will ask the following questions given income statement data.

  1. what is the highest value of cost of goods and service?
  2. what is the largest gross profit margin?
  3. what is the minimum ratio of operating income loss divided by non operating income expense?

QnA over Multiple Tables

We now make the task for the Agent more complicated, by asking it a question that answer can be computed only by retrieving relevant information from multiple tables:

  • Q: What is the ratio of the largest stockholders equity to the smallest revenue?

As you will see below, this question can be obtained only by accessing both the balance sheet and the income statement.

question_dict ={
    'q1': ['what is the ratio of the largest stockholders equity to the smallest revenue'],
}
# get the largest stockholders equity
x = balance_sheet['StockholdersEquity'].astype(float).max()
print(f"The largest stockholders equity value is: {x}")

# get the smallest revenue
y = income_statement['RevenueFromContractWithCustomerExcludingAssessedTax'].astype(float).min()
print(f"The smallest revenue value is: {y}")

# compute the ratio
ratio = x/y
print(f"Their ratio is: {ratio}")
The largest stockholders equity value is: 134047000000.0
The smallest revenue value is: 53809000000.0
Their ratio is: 2.4911631883142227

Error Resilience

In the previous example over single table, the model successfully answered your questions. However, the model may not always have access to the preview of the data. You will see that when we remove the preview from the preamble, the model is run into an error and not produce the answer. We will solve this problem with two different ways:

  1. Asking the model to keep trying until it fixes the issue.
  2. Giving the model another tool to view the data and telling it to preview the data before writing code.

You will see that the second method is able to come to the answer with fewer steps.

preamble = """

"""

question1 = "what is the highest value of cost of goods and service?"

output = cohere_agent(question1, preamble, tools, verbose=True)
running 0th step.

== tool results: [{'python_answer': "KeyError('cost of goods and service')"}]
Sorry, there is no column named 'cost of goods and service' in the dataframe.

As you see above, the model failed to execute because it assumed certain column names but they turned out to be wrong. One simple fix is to tell the model to continue to solve the problem in the face of error.

CrewAI

Now let's Attemp to replicate the same thing using CrewAI but with GPT3.5

I liked using CrewAI more. It feels simpler and better explained. Their docs could use an update, but the idea behind it is nice. The documentation recommends splitting the tasks into smaller chunks and assigning one agent for each task, but here, I just did one big chunk, and it works (kind of). It did work better on a different case when I split the task into smaller parts. I will make sure to post that later when it’s complete, and I’m happy with the results.

from crewai import Agent, Task, Crew, Process

# Creating the task to combine results into a JSON format
python_evaluator = Task(
    description=(
        f"You are an expert who answers the user's question. You are working with a pandas dataframe in Python. The name of the dataframe is f`{income_statement.head(3)}`. "
        "Always view the data first to write flawless code."
    ),
    expected_output="results of the code's output in a nice format",
    agent=Agent(
        role='Senior Python Engineer',
        goal='Successfully run the script and return the results in a useful format',
        verbose=True,
        memory=True,
        backstory=(

        ),
        allow_delegation=False,
        allow_code_execution=True,
    ),
)
crew = Crew(
        agents=[python_evaluator.agent],
        tasks=[python_evaluator],
        process=Process.sequential
    )

# Kickoff the crew with the provided text response

result = crew.kickoff(inputs=inputs)

Thought: I now can give a great answer. To perform data aggregation and return the results in a useful format, I need to write a Python script using the pandas library. The goal is to take the provided dataframe and aggregate the data to get meaningful insights.

Here’s the code to aggregate the data and output the results:

```python
import pandas as pd
import numpy as np

# Sample data creation based on the provided dataframe structure
data = {
    "index": ["2017-10-01-2018-09-29", "2018-09-30-2018-12-29", "2018-09-30-2019-09-28"],
    "RevenueFromContractWithCustomerExcludingAssessedTax": [265595000000, 84310000000, 260174000000],
    "CostOfGoodsAndServicesSold": [163756000000, np.nan, 161782000000],
    "GrossProfit": [101839000000, 32031000000, 98392000000],
    "ResearchAndDevelopmentExpense": [14236000000, np.nan, 16217000000],
    "SellingGeneralAndAdministrativeExpense": [16705000000, np.nan, 18245000000],
    "OperatingExpenses": [30941000000, np.nan, 34462000000],
    "OperatingIncomeLoss": [70898000000, np.nan, 63930000000],
    "NonoperatingIncomeExpense": [2005000000, np.nan, 1807000000],
    "IncomeLossFromContinuingOperationsBeforeIncomeTaxesExtraordinaryItemsNoncontrollingInterest": [72903000000, np.nan, 65737000000],
    "IncomeTaxExpenseBenefit": [13372000000, np.nan, 10481000000],
    "NetIncomeLoss": [59531000000, 19965000000, 55256000000],
    "EarningsPerShareBasic": [3.00, 1.05, 2.99],
    "EarningsPerShareDiluted": [2.98, 1.05, 2.97],
    "WeightedAverageNumberOfSharesOutstandingBasic": [19821510000, np.nan, 18471340000],
    "WeightedAverageNumberOfDilutedSharesOutstanding": [20000440000, np.nan, 18595650000],
}

# Create the dataframe
df = pd.DataFrame(data)

# Display the dataframe to ensure it's created correctly
print("Original DataFrame:")
print(df)

# Perform aggregation on the dataframe
# For simplicity, let's calculate the average Gross Profit and Net Income Loss
average_gross_profit = df['GrossProfit'].mean()
average_net_income_loss = df['NetIncomeLoss'].mean()

# Constructing the result dictionary
result = {
    "Average Gross Profit": average_gross_profit,
    "Average Net Income Loss": average_net_income_loss,
}

print("\nAggregated Results:")
print(result)
```

Running the above code will provide us with the average Gross Profit and average Net Income Loss from the dataset.

Thought: I now can give a great answer. 

To effectively work with the given dataframe, I will first inspect the data to understand its structure. Then, I will perform data aggregation and analysis as required. Let's start by viewing the data.

```python
import pandas as pd

# Assuming the dataframe is already loaded and named `df`
print(df)
```

Once we have a clear view of the data, we can proceed with any specific calculations or transformations required.

Thought: I now can give a great answer by viewing the data and writing code to handle it effectively.

Let's start by viewing the data to ensure we understand its structure and then proceed with writing the appropriate code.

Here is the data in a pandas DataFrame:

```python
