Cloud GPU Integration Guide

This document provides instructions for using the cloud-based GPU version of the AI-Powered Facial and Body Feature Editor, which leverages InstructPix2Pix for GPU-accelerated processing without requiring any local setup.

Overview

The cloud-based GPU version of the application uses InstructPix2Pix, a public GPU-accelerated Space on Hugging Face, to process your images. This approach offers several benefits:

• GPU-accelerated processing without local setup
• Works on any device with internet access
• No need to install CUDA or PyTorch
• Simpler deployment and maintenance

How It Works

1. Your image is sent to the InstructPix2Pix Space
2. Your feature selections are converted to text instructions
3. The Space processes your image using GPU acceleration
4. The edited image is returned to the interface

Setup Instructions

1. Download the app_cloud_gpu.py file
2. Replace your current app.py file in your Hugging Face Space with this file
3. Commit and push the changes to your Space
4. Your Space will automatically rebuild with the cloud GPU integration

# In your local repository
cp app_cloud_gpu.py app.py
git add app.py
git commit -m "Implement cloud GPU integration with InstructPix2Pix"
git push

Feature Mapping

The application maps your feature selections to text instructions that InstructPix2Pix can understand:

Feature Type	Modification Type	Instruction
Eyes	Larger	"make the eyes larger"
Eyes	Smaller	"make the eyes smaller"
Face Shape	Slim	"make the face slimmer"
Lips	Fuller	"make the lips fuller"
...	...	...

The intensity slider modifies these instructions:

• Low intensity (0.1-0.3): Adds "slightly" to the instruction
• Medium intensity (0.4-0.7): Uses the base instruction
• High intensity (0.8-1.0): Adds "dramatically" to the instruction

Custom Prompts

You can also use custom prompts for more specific edits. Enable the "Use Custom Prompt" checkbox and enter your desired instruction, such as:

• "make the eyes blue and add long eyelashes"
• "add a subtle smile"
• "make the hair curly and blonde"

Performance Considerations

• Processing typically takes 10-30 seconds depending on server load
• The InstructPix2Pix Space may have usage limits or queues
• Images are automatically resized to 512x512 pixels for optimal processing

Troubleshooting

If you encounter issues:

1. Connection errors: The InstructPix2Pix Space might be temporarily unavailable. Try again later.
2. Processing errors: Try a different image or a simpler edit instruction.
3. Unexpected results: Adjust your instruction or try using a custom prompt for more control.

Limitations

• Less precise control compared to direct feature manipulation
• Results depend on how well InstructPix2Pix understands the instructions
• Subject to the availability of the public InstructPix2Pix Space

Future Improvements

• Add support for additional public GPU Spaces
• Implement a fallback mechanism if InstructPix2Pix is unavailable
• Expand the instruction mapping for more specific edits
