Welcome to this comprehensive guide on utilizing the Fine-Tuned Llama 3 Instruct model specifically designed for function calling! Llama 3 is a state-of-the-art text generation model that excels in processing natural language and can be tailored for various tasks, particularly function invocation. This article will focus on getting you set up quickly, provide insight into important concepts, and offer troubleshooting tips to handle any hiccups along the way.

What You Need to Get Started

• Python installed on your machine
• Access to the Hugging Face model repository (you may need to log in)
• Basic knowledge of Python coding and command line interface
• Your creativity to experiment with function calling

Quick Server Setup

Begin your journey by utilizing a one-click template for TGI (Text Generation Inference). Simply follow the link below:

To learn the step-by-step setup of your inference model, here’s a helpful YouTube Video guiding you through the process!

Understanding Inference Scripts

Inference scripts are akin to detailed recipes — they outline the ingredients (or prompts) you need and the steps to follow. The Fine-Tuned Llama 3 model expressly supports TGI, vLLM and Llama.cpp, which allows you to automate function calls. Let’s delve into the structure of a sample prompt format.

Sample Prompt Format

To interact seamlessly with the model, we set up a coherent structure akin to building a bridge between our needs (user input) and the model’s capabilities (function output). Below are the structural components you need to create your prompt:

Set up messages:[
    {role: "function_metadata", content: FUNCTION_METADATA},
    {role: "user", content: "What is the current weather in London?"},
    {role: "function_call", content: 
        {name: "get_current_weather", 
        arguments: {city: "London"}},
    },
    {role: "function_response", content: 
        {temperature: "15 C", condition: "Cloudy"}},
    {role: "assistant", content: "The current weather in London is Cloudy with a temperature of 15 Celsius"}
]

Here, each component fulfills a role: the user asks for the weather, while the assistant interprets and delivers this output.

Applying Function Metadata

Function metadata provides crucial context. This is like the GPS coordinates for your bridge, helping the model understand where to direct its outputs:

FUNCTION_METADATA = [
    {type: "function", function: 
        {name: "get_current_weather",
        description: "This function gets the current weather in a given city",
        parameters: {
            type: "object",
            properties: {
                city: {type: "string", description: "The city, e.g., San Francisco"},
                format: {
                    type: "string",
                    enum: ["celsius", "fahrenheit"],
                    description: "The temperature unit to use."
                },
            },
            required: ["city"]
        }}}
]

The function names, descriptions, and required parameters serve as the nuts and bolts of your operation.

Troubleshooting

Even the best models may not work perfectly on the first try. Here are some common issues you might encounter and how to resolve them:

• If the model doesn’t seem to respond, ensure you’ve installed the necessary dependencies correctly using pip install huggingface_hub and successfully logged in using huggingface-cli login.
• Keep an eye out for any syntax errors in your command line inputs or your prompt. This often leads to confusion — just like a recipe gone awry!
• Be mindful of the environment in which you’re running the model. If you are using a gated model, ensure that you have the appropriate access rights.
