Hugging Face Gemma Recipes Project Detailed Introduction

Project Overview

huggingface-gemma-recipes is an open-source project officially maintained by Hugging Face, designed to provide users with minimized example code and tutorials related to the Google Gemma series models. The core goal of this project is to help developers quickly get started with Gemma model inference, fine-tuning, and various practical application scenarios.

Project Features

🚀 Quick Start

• Provides the most simplified code examples to lower the learning threshold.
• Supports multi-modal input processing (text, image, audio).
• Integrates the latest Transformers library features.

🎯 Multi-Modal Support

This project supports the multi-modal capabilities of the Gemma 3 series models:

• Pure Text Processing: Traditional text generation and question answering.
• Image Understanding: Image captioning, visual question answering.
• Audio Processing: Speech-to-text, audio analysis.
• Multi-Modal Interaction: Mixed input of text, images, and audio.

Core Functionality

1. Model Inference

The project provides a unified model inference interface, supporting quick loading and use of Gemma models:

from transformers import AutoProcessor, AutoModelForImageTextToText
import torch

model_id = "google/gemma-3n-e4b-it"  # or google/gemma-3n-e2b-it
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForImageTextToText.from_pretrained(model_id).to(device)

def model_generation(model, messages):
    inputs = processor.apply_chat_template(
        messages,
        add_generation_prompt=True,
        tokenize=True,
        return_dict=True,
        return_tensors="pt",
    )
    input_len = inputs["input_ids"].shape[-1]
    inputs = inputs.to(model.device, dtype=model.dtype)
    
    with torch.inference_mode():
        generation = model.generate(**inputs, max_new_tokens=32, disable_compile=False)
        generation = generation[:, input_len:]
        decoded = processor.batch_decode(generation, skip_special_tokens=True)
        print(decoded[0])

2. Usage Examples

Pure Text Processing

# Text Question Answering
messages = [
    {
        "role": "user",
        "content": [
            {"type": "text", "text": "What is the capital of France?"}
        ]
    }
]
model_generation(model, messages)

Audio Processing

# Speech-to-Text
messages = [
    {
        "role": "user",
        "content": [
            {"type": "text", "text": "Transcribe the following speech segment in English:"},
            {"type": "audio", "audio": "https://huggingface.co/datasets/ariG23498/demo-data/resolve/main/speech.wav"},
        ]
    }
]
model_generation(model, messages)

Image Understanding

# Image Captioning
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "image": "https://huggingface.co/datasets/ariG23498/demo-data/resolve/main/airplane.jpg"},
            {"type": "text", "text": "Describe this image."}
        ]
    }
]
model_generation(model, messages)
