locallab 0.2.3

A lightweight AI inference server for running models locally or in Google Colab

🚀 LocalLab

LocalLab is a powerful, lightweight AI inference server designed to deliver cutting-edge language model capabilities on your local machine or through Google Colab. It empowers developers and researchers to run sophisticated AI models on local hardware, optimizing resources with advanced features such as dynamic model loading, memory optimizations, and real-time system monitoring.

What Problem Does LocalLab Solve?

• Local Inference: Run advanced language models without relying on expensive cloud services.
• Optimized Performance: Utilize state-of-the-art techniques like quantization, attention slicing, and CPU offloading for maximum efficiency.
• Seamless Deployment: Easily switch between local deployment and Google Colab, leveraging ngrok for public accessibility.
• Effective Resource Management: Automatically monitor and manage CPU, RAM, and GPU usage to ensure smooth operation.

Get Started

1. Installation:

   pip install locallab
   

2. Starting the Server Locally:

   from locallab import start_server
   start_server()
   

3. Starting the Server on Google Colab:

   !pip install locallab
   
   # Set up your ngrok auth token (REQUIRED for public access)
   # Get your free token from: https://dashboard.ngrok.com/get-started/your-authtoken
   import os
   os.environ["NGROK_AUTH_TOKEN"] = "your_token_here"
   
   # Optional: Configure model and optimizations
   os.environ["HUGGINGFACE_MODEL"] = "microsoft/phi-2"  # Choose your preferred model
   os.environ["LOCALLAB_ENABLE_QUANTIZATION"] = "true"  # Enable model optimizations
   
   # Start the server with ngrok for public access
   from locallab import start_server
   start_server(use_ngrok=True)  # Creates a public URL accessible from anywhere
   

4. Connecting your Client:

   from locallab.client import LocalLabClient
   
   # Use the ngrok URL displayed in the output above
   client = LocalLabClient("https://xxxx-xxx-xxx-xxx.ngrok.io")
   
   # Test the connection
   response = client.generate("Hello, how are you?")
   print(response)
