TaskWeaver

     

TaskWeaver is A code-first agent framework for seamlessly planning and executing data analytics tasks. This innovative framework interprets user requests through code snippets and efficiently coordinates a variety of plugins in the form of functions to execute data analytics tasks in a stateful manner.

Unlike many agent frameworks that only track the chat history with LLMs in text, TaskWeaver preserves both the chat history and the code execution history, including the in-memory data. This feature enhances the expressiveness of the agent framework, making it ideal for processing complex data structures like high-dimensional tabular data.

💥 Highlights

• Rich data structure - TaskWeaver allows you to work with rich data structures in Python, such as DataFrames, instead of dealing with strings.
• Customized algorithms - TaskWeaver allows you to encapsulate your own algorithms into plugins and orchestrate them.
• Incorporating domain-specific knowledge - TaskWeaver is designed to incorporate domain-specific knowledge easily to improve the reliability.
• Stateful execution - TaskWeaver is designed to support stateful execution of the generated code to ensure consistent and smooth user experience.
• Code verification - TaskWeaver is designed to verify the generated code before execution. It can detect potential issues in the generated code and provide suggestions to fix them.
• Easy to use - TaskWeaver is easy to use with sample plugins, examples and tutorials to help you get started. TaskWeaver offers an open-box experience, allowing users to run it immediately after installation.
• Easy to debug - TaskWeaver is easy to debug with detailed and transparent logs to help you understand the entire process, including LLM prompts, the code generation, and execution process.
• Security consideration - TaskWeaver supports a basic session management to keep different users' data separate. The code execution is separated into different processes to avoid mutal interference.
• Easy extension - TaskWeaver is easy to extend to accomplish more complex tasks with multiple agents as the plugins.

✨ Quick Start

🛠️ Step 1: Installation

TaskWeaver requires Python >= 3.10. It can be installed by running the following command:

# [optional to create conda environment]
# conda create -n taskweaver python=3.10
# conda activate taskweaver

# clone the repository
git clone https://github.com/microsoft/TaskWeaver.git
cd TaskWeaver
# install the requirements
pip install -r requirements.txt

🖊️ Step 2: Configure the LLMs

Before running TaskWeaver, you need to provide your LLM configurations. Taking OpenAI as an example, you can configure taskweaver_config.json file as follows.

OpenAI

{
  "llm.api_key": "the api key",
  "llm.model": "the model name, e.g., gpt-4"
}

💡 TaskWeaver also supports other LLMs and advanced configurations, please check the documents for more details.

🚩 Step 3: Start TaskWeaver

⌨️ Command Line (CLI)

# assume you are in the cloned TaskWeaver folder
python -m taskweaver -p ./project/

This will start the TaskWeaver process and you can interact with it through the command line interface. If everything goes well, you will see the following prompt:

=========================================================

🎬 Demo Examples

The demos were made based on the web UI, which is better for displaying the generated artifacts such as images. The demos could also be conducted in the command line interface.

1️⃣📉 Example 1: Pull data from a database and apply an anomaly detection algorithm

In this example, we will show you how to use TaskWeaver to pull data from a database and apply an anomaly detection algorithm.

anomaly_detection_chainlit.mp4

If you want to follow this example, you need to configure the sql_pull_data plugin in the project/plugins/sql_pull_data.yaml file. You need to provide the following information:

api_type: azure or openai
api_base: ...
api_key: ...
api_version: ...
deployment_name: ...
sqlite_db_path: sqlite:///../../../sample_data/anomaly_detection.db

The sql_pull_data plugin is a plugin that pulls data from a database. It takes a natural language request as input and returns a DataFrame as output.

This plugin is implemented based on Langchain. If you want to follow this example, you need to install the Langchain package:

pip install langchain
pip install tabulate

2️⃣🏦 Example 2: Forecast QQQ's price in the next 7 days

In this example, we will show you how to use TaskWeaver to forecast QQQ's price in the next 7 days.

forecast_price_chainlit.mp4

If you want to follow this example, you need to ensure you have these two requirements installed:

pip install yfinance
pip install statsmodels

For more examples, please refer to our paper.

💡 The planning of TaskWeaver are based on the LLM model. Therefore, if you want to repeat the examples, the execution process may be different from what you see in the videos. For example, in the second demo, the assistant may ask the user which prediction algorithm should be used. Typically, more concrete prompts will help the model to generate better plans and code.
