Step 1: Set Up Your Environment

1. Hardware Requirements: Ensure you have access to NVIDIA GPUs, ideally A100 80GB VRAM, to run the model (Llama3:70b) efficiently. In my case I rent A100 GPU from Digital Ocean Paperspace. Please see the screenshot. OS: Ubuntu 22.04 Disk Size: At least 200 GB (llama3:70b)-> 40GB, (llama3:8b)-> 5GB

   

   ssh paperspace@XXX.XXX.XXX.XXX

2. First git clone the repository

   cd ~
   git clone https://github.com/aidatatools/LLM_Sentinel.git
   cd LLM_Sentinel

3. venv:

   Ensure you have Python 3.10 or later installed.

   cd ~/LLM_Sentinel
   python3.10 -m venv venv
   source venv/bin/activate

4. Install requirements.txt

   pip install -r requirements.txt

5. Check the backend ollama service is running, and the model (llama3:8b)(for DEV) or (llama3:70b)(for Production) exists. If you are not familiar with ollama, please visit https://ollama.com

   ollama list
   curl http://127.0.0.1:11434

6. Copy .env.example to .env and set the variable(ENV_PROD) to True or False

   echo 'ENV_PROD=False' > .env

Step 2: Start the Web UI to Interact with Chatbot

1. Start the WebUI in terminal:

   python chatbot3.py

2. Open a browser, and visit the site with port number:

   http://127.0.0.1:7860
