🤗 AutoQuantNX

Overview

AutoQuantNX is a powerful Gradio-based web application designed to simplify the process of optimizing and deploying Hugging Face models. It supports a wide range of tasks, including quantization, ONNX conversion, and seamless integration with the Hugging Face Hub. With AutoQuantNX, you can easily convert models to ONNX format, apply quantization techniques, and push the optimized models to your Hugging Face account—all through an intuitive user interface.

In the deployed UI, only 16 Bit quantization works because of GPU requirement of BitsAndBytes and no GPU availability in free HF space.

Features

Supported Tasks

AutoQuantNX supports the following tasks:

• Text Classification
• Named Entity Recognition (NER)
• Question Answering
• Causal Language Modeling
• Masked Language Modeling
• Sequence-to-Sequence Language Modeling
• Multiple Choice
• Whisper (Speech-to-Text)
• Embedding Fine-Tuning
• Image Classification (Placeholder for future implementation)

Quantization Options

• None (default)
• 4-bit
• 8-bit
• 16-bit-float

ONNX Conversion

Converts models to ONNX format for optimized deployment.

Supports optional ONNX quantization:

• 8-bit
• 16-bit-int
• 16-bit-float

Hugging Face Hub Integration

• Automatically pushes optimized models to your Hugging Face Hub repository
• Tags models with metadata for easy identification (e.g., onnx, quantized, task type)

Performance Testing

Compares original and quantized models using metrics like:

• Mean Squared Error (MSE)
• Spearman Correlation
• Cosine Similarity
• Inference Time
• Model Size

Prerequisites

Using requirements.txt (Not preferable to me atleast)

• Python 3.8 or higher
• Install dependencies:

  pip install -r requirements.txt

Using Poetry

1. Install Poetry (if not already installed):

   Linux:

   curl -sSL https://install.python-poetry.org | python3 -

   Other platforms: Follow the official instructions.

2. Install dependencies:

   poetry install

3. Activate the virtual environment:

   poetry shell

Usage

Launch the App

Run the following command to start the Gradio web application:

python src/app.py

The app will be accessible at http://localhost:7860 by default.

Steps to Use the App

1. Enter Model Details:

   • Provide the Hugging Face model name
   • Select the task type (e.g., text classification, question answering)

2. Select Optimization Options:

   • Choose quantization type (e.g., 4-bit, 8-bit)
   • Enable ONNX conversion and select quantization options if needed

3. Provide Hugging Face Token:

   • Enter your Hugging Face token for accessing and pushing models to the Hub

4. Start Conversion:

   • Click the "Start Conversion" button to process the model

5. Monitor Progress:

   • View real-time status updates, resource usage, and results directly in the app

6. Push to Hub:

   • Optimized models are automatically pushed to your specified Hugging Face repository

Example

For a model like bert-base-uncased performing text classification:

1. Select text_classification as the task
2. Enable quantization (e.g., 8-bit)
3. Enable ONNX conversion with optimization
4. Click "Start Conversion" and monitor progress

Key Functions

app.py

• process_model: Main function handling model quantization, ONNX conversion, and Hugging Face Hub integration
• update_memory_info: Monitors and displays system resource usage

optimization/onnx_conversion.py

• convert_to_onnx: Converts models to ONNX format
• quantize_onnx_model: Quantizes ONNX models for optimized inference

optimization/quantize.py

• ModelQuantizer: Handles quantization of PyTorch models and performance testing

utilities/push_to_hub.py

• push_to_hub: Pushes models to the Hugging Face Hub

utilities/resources.py

• ResourceManager: Manages temporary files and memory usage

Notes

• Ensure you have sufficient system resources for model conversion and quantization
• Use a Hugging Face Hub token with proper write permissions for pushing models

Troubleshooting

• Model Conversion Fails: Ensure the model and task are supported
• Insufficient Resources: Free up memory or reduce optimization levels
• ONNX Quantization Errors: Verify that the selected quantization type is supported for the model
