MeKB-Sim: Personal Knowledge Base-Powered Multi-Agent Simulation 🌐

🚀 We are excited to introduce MeKB-Sim, a multi-agent simulation platform that closely mimic real-life interactions, based on a dynamic personal knowledge base, termed MeKB.

🤖 The MeKB of each agent consists of attributes crucial for modeling theory of mind, such as linguistic style, personality, and memory. The dynamic nature of MeKB to enable agents to adapt their activities and interactions with other agents effectively.

Our platform includes a Unity WebGL game interface for visualization and an interactive monitoring panel that presents the agents’ planning, actions, and MeKBs over time. Dive into our simulation 🕹️ – click the image below for a YouTube video walkthrough!

🌟 Environment

Dependency

python: 3.9.18
mysql: 8.0.31
node.js: 18.19.1

Folder Creation

mkdir logs
mkdir actions
mkdir snapshot

Mysql Init

create database `llm_account` default character set utf8mb4 collate utf8mb4_unicode_ci;
create database `llm_game` default character set utf8mb4 collate utf8mb4_unicode_ci;
create database `llm_game0001` default character set utf8mb4 collate utf8mb4_unicode_ci;
create database `llm_game0002` default character set utf8mb4 collate utf8mb4_unicode_ci;

In order to connect to mysql, you need to modify config/app.json.

Install

pip install -r requirements.txt

⚡️ How to deploy your demo

Code Modification

You need to modify the contents marked with "### TODO" in the following files

agent/agent/agent.py
agent/utils/llmExpends/gpt4.py
agent/utils/llmExpends/gpt35.py
main.py
show_actions.py

Besides, modify the contents marked with "// TODO" in client/Build/Builds.framework.js

Run

1. To start the demo backend, run

python main.py

When you see

--------Server Started--------

The backend has been started successfully.

2. To start the unity webgl client, open client/index.html in your browser.

a. Right-clicking the index.html in your python IDE and select open in browser.

b. Or in directory client, run

python -m http.server 7042 --bind 0.0.0.0

Then visit the following address in your browser

http://127.0.0.1:7042

When you see

somebody linked.

The client has been started successfully.

3. To start the backend of the monitoring page, run

python show_actions.py

4. To start the Vue front-end of the monitoring page

Create a new vue project and replace the corresponding files in the new vue project with the two files under monitor_page-vue/src.

Then modify the backendServer in the main.js

5. Start Simulation

You can start tick with the buttons on the web client. You can also start with:

python tick.py

6. Restart

rm -f snapshot/app.json
rm -f actions/*

drop database llm_account;
drop database llm_game0001;
create database `llm_game0001` default character set utf8mb4 collate utf8mb4_unicode_ci;
create database `llm_account` default character set utf8mb4 collate utf8mb4_unicode_ci;

Then re-run

python main.py
