# InfiniteTalk - Deployment Guide

## Prerequisites

1. **HuggingFace Account**: Sign up at https://huggingface.co
2. **Git & Git LFS**: Install from https://git-scm.com
3. **HuggingFace CLI** (optional but recommended):
   ```bash
   pip install huggingface_hub
   huggingface-cli login
   ```

## Deployment Steps

### Option 1: Web UI (Easiest)

1. **Create New Space**
   - Go to https://huggingface.co/new-space
   - Space name: `infinitetalk` (or your choice)
   - License: `apache-2.0`
   - SDK: `Gradio`
   - Hardware: `ZeroGPU` (free tier available!)
   - Click "Create Space"

2. **Upload Files**
   - Click "Files" tab in your new Space
   - Upload all files from this directory:
     - `README.md` (with YAML metadata)
     - `app.py`
     - `requirements.txt`
     - `packages.txt`
     - `.gitignore`
     - `src/` folder
     - `wan/` folder
     - `utils/` folder
     - `assets/` folder (optional)
     - `examples/` folder (optional)
     - `LICENSE.txt`

3. **Wait for Build**
   - Space will automatically build
   - First build takes 5-10 minutes (installing dependencies)
   - Check "Logs" tab for build progress
   - Watch for any error messages

4. **Test Your Space**
   - Once built, the Space will show "Running"
   - First generation will download models (~2-3 minutes)
   - Try with example images/audio

### Option 2: Git (Advanced)

1. **Clone Your Space**
   ```bash
   git clone https://huggingface.co/spaces/YOUR_USERNAME/YOUR_SPACE_NAME
   cd YOUR_SPACE_NAME
   ```

2. **Copy Files**
   ```bash
   # From your local infinitetalk-hf-space directory
   cp -r /path/to/infinitetalk-hf-space/* .
   ```

3. **Commit and Push**
   ```bash
   git add .
   git commit -m "Initial InfiniteTalk Space deployment"
   git push
   ```

4. **Monitor Build**
   - Go to your Space URL
   - Check "Logs" for build progress

### Option 3: CLI Upload

```bash
# From this directory
huggingface-cli upload YOUR_USERNAME/YOUR_SPACE_NAME . --repo-type=space
```

## Troubleshooting

### Build Fails with Flash-Attn Error

**Symptom**: `flash-attn` compilation fails

**Solutions**:
1. Try adding to `requirements.txt`:
   ```
   flash-attn==2.7.4.post1 --no-build-isolation
   ```

2. Or use Dockerfile approach (create `Dockerfile`):
   ```dockerfile
   FROM nvidia/cuda:12.1.0-devel-ubuntu22.04

   RUN apt-get update && apt-get install -y \
       python3.10 python3-pip git ffmpeg build-essential libsndfile1

   WORKDIR /app

   # Install PyTorch first
   RUN pip install torch==2.4.1 torchvision==0.19.1 torchaudio==2.4.1

   # Install flash-attn with pre-built wheels
   RUN pip install flash-attn==2.7.4.post1 --no-build-isolation

   # Copy and install requirements
   COPY requirements.txt .
   RUN pip install -r requirements.txt

   # Copy application
   COPY . .

   CMD ["python3", "app.py"]
   ```

### Models Not Downloading

**Symptom**: "Model download failed" error

**Solutions**:
1. Check HuggingFace is not down: https://status.huggingface.co
2. Add HF_TOKEN secret in Space settings (for private models)
3. Check model repository IDs in `utils/model_loader.py`

### Out of Memory (OOM) Errors

**Symptom**: "CUDA out of memory"

**Solutions**:
1. Reduce resolution (use 480p instead of 720p)
2. Reduce diffusion steps (try 30 instead of 40)
3. Process shorter videos
4. Check `utils/gpu_manager.py` settings

### Space Stuck in "Building"

**Symptom**: Build takes >15 minutes

**Solutions**:
1. Check "Logs" tab for errors
2. Flash-attn compilation can take 10+ minutes
3. If timeout, try Dockerfile approach
4. Consider pre-built flash-attn wheels

### ZeroGPU Quota Exceeded

**Symptom**: "GPU quota exceeded"

**Solutions**:
1. **Free Tier**: Wait for quota to refill (1 ZeroGPU second = 30 real seconds)
2. **Upgrade to PRO**: $9/month for 8× quota
3. **Apply for Grant**: Community GPU Grant for innovative projects
4. Optimize generation time (reduce steps, use 480p)

## Post-Deployment

### Monitor Usage
- Check "Logs" tab regularly
- Monitor GPU quota in Space settings
- Watch for user error reports in Community tab

### Update Space
```bash
# Make changes locally
git add .
git commit -m "Update: [description]"
git push
```

Space will automatically rebuild on push.

### Add Examples
Upload example images and audio to `examples/` folder to help users get started quickly.

### Enable Discussions
In Space settings, enable "Discussions" to get user feedback.

### Apply for Community GPU Grant
If your Space is popular and useful:
1. Go to Space Settings
2. Click "Apply for community GPU grant"
3. Explain your project's value to the community

## Hardware Options

### Free ZeroGPU
- **Cost**: FREE
- **Limits**: 300s per session, 600s max quota
- **Best for**: Testing, light usage, demos
- **GPU**: H200 with 70GB VRAM

### PRO ZeroGPU
- **Cost**: $9/month
- **Benefits**: 8× quota, priority queue, 10 Spaces
- **Best for**: Regular usage, public demos

### Dedicated GPU (Paid)
- **T4 (16GB)**: $0.60/hour - Too small for InfiniteTalk
- **A10G (24GB)**: $1.05/hour - Minimum viable
- **A100 (40GB)**: $3.00/hour - Overkill but works
- **Best for**: Private, dedicated instances

## Performance Expectations

### First Generation
- Model download: 2-3 minutes
- Generation (10s video, 480p): 40 seconds
- **Total**: ~3-4 minutes

### Subsequent Generations
- Generation (10s video, 480p): 35-40 seconds
- Generation (10s video, 720p): 60-70 seconds

### Free Tier Usage
- ~3-5 generations per quota period (600s ZeroGPU)
- Quota refills gradually (1 ZeroGPU second per 30 real seconds)
