+# Hugging Face Spaces Deployment Guide
+
+## Key Changes for ZeroGPU Support
+
+### 1. Import Order (CRITICAL!)
+The `spaces` package **must** be imported before any CUDA-related packages:
+
+```python
+# CORRECT ✅
+import spaces
+import torch
+import cv2
+
+# WRONG ❌
+import torch
+import spaces  # Too late!
+```
+
+### 2. GPU Decorator
+Use `@spaces.GPU` decorator on functions that need GPU:
+
+```python
+@spaces.GPU
+def sam_refine(video_state, point_prompt, click_state, evt):
+    initialize_models()  # Lazy load on first use
+    # ... GPU code here
+
+@spaces.GPU(duration=120)  # Specify duration for long tasks
+def run_videomama_with_sam2(video_state, click_state):
+    # ... GPU code here
+```
+
+### 3. Lazy Model Loading
+Models should be initialized on first use, not at app startup:
+
+```python
+# Global model variables
+sam2_tracker = None
+videomama_pipeline = None
+
+def initialize_models():
+    global sam2_tracker, videomama_pipeline
+    if sam2_tracker is not None:
+        return  # Already loaded
+    # Load models here...
+
+# In GPU functions:
+@spaces.GPU
+def inference_function():
+    initialize_models()  # Load on first use
+    # Use models...
+```
+
+### 4. Requirements
+Add `spaces` to `requirements.txt`:
+
+```txt
+# CRITICAL: Hugging Face ZeroGPU support
+spaces
+
+# Other packages...
+torch>=2.0.0
+gradio==4.31.0
+```
+
+### 5. README Configuration
+Update `README.md` with hardware specification:
+
+```yaml
+---
+title: VideoMaMa
+sdk: gradio
+sdk_version: 4.31.0
+app_file: app.py
+python_version: "3.10"
+hardware: zero-a10g  # For ZeroGPU Pro
+---
+```
+
+## Available Hardware Options
+
+For Pro subscribers:
+- `zero-a10g` - NVIDIA A10G (24GB VRAM) - Recommended
+- `zero-a100` - NVIDIA A100 (40GB VRAM) - For larger models
+
+## Duration Parameter
+
+The `duration` parameter specifies GPU allocation time:
+```python
+@spaces.GPU(duration=60)   # 1 minute - good for single image
+@spaces.GPU(duration=120)  # 2 minutes - good for short videos
+@spaces.GPU(duration=300)  # 5 minutes - for long processing
+```
+
+## Testing Locally
+
+To test without ZeroGPU:
+```python
+# Mock the spaces decorator for local testing
+try:
+    import spaces
+except ImportError:
+    # Mock for local development
+    class MockSpaces:
+        @staticmethod
+        def GPU(duration=None):
+            def decorator(func):
+                return func
+            return decorator if duration else lambda f: f
+    spaces = MockSpaces()
+```
+
+## Common Errors
+
+### Error: "CUDA has been initialized before importing spaces"
+**Solution**: Move `import spaces` to the very top of `app.py`, before any other imports.
+
+### Error: "GPU time exceeded"
+**Solution**: Increase the `duration` parameter in `@spaces.GPU(duration=X)`.
+
+### Error: "Out of memory"
+**Solution**: 
+- Use smaller batch sizes
+- Clear CUDA cache: `torch.cuda.empty_cache()`
+- Consider requesting `zero-a100` hardware
+
+## Deployment Checklist
+
+- [ ] `import spaces` is the FIRST import in app.py
+- [ ] All GPU functions have `@spaces.GPU` decorator
+- [ ] Models use lazy loading (initialized on first use)
+- [ ] `spaces` is in requirements.txt
+- [ ] README.md specifies `hardware: zero-a10g`
+- [ ] Tested locally without errors
+- [ ] Git pushed to Hugging Face Space repository
+
+## Files Modified
+
+1. **app.py**
+   - Added `import spaces` at the top
+   - Added `@spaces.GPU` decorators to GPU functions
+   - Implemented lazy model loading
+   - Removed model initialization from main block
+
+2. **requirements.txt**
+   - Added `spaces` package
+
+3. **README.md**
+   - Added hardware configuration
+   - Set correct Gradio version

+# Quick Start: Fix ZeroGPU CUDA Error
+
+## The Problem
+```
+RuntimeError: CUDA has been initialized before importing the `spaces` package.
+```
+
+## The Solution (Applied ✅)
+
+### 1. Import `spaces` FIRST in app.py
+```python
+# BEFORE (❌ Wrong):
+import os
+import torch
+import spaces  # Too late!
+
+# AFTER (✅ Fixed):
+import spaces  # MUST BE FIRST!
+import os
+import torch
+```
+
+### 2. Add GPU Decorators
+```python
+@spaces.GPU
+def sam_refine(...):
+    initialize_models()  # Lazy load
+    # ... processing
+
+@spaces.GPU(duration=120)  # 2 minutes for video processing
+def run_videomama_with_sam2(...):
+    initialize_models()  # Lazy load
+    # ... processing
+```
+
+### 3. Lazy Load Models
+```python
+# Don't load at startup:
+if __name__ == "__main__":
+    # initialize_models()  # ❌ Remove this
+    demo.launch()
+
+# Load on first use instead:
+@spaces.GPU
+def inference_function():
+    initialize_models()  # ✅ Load here
+    # ...
+```
+
+### 4. Update requirements.txt
+```txt
+spaces  # Add this at the top
+torch>=2.0.0
+gradio==4.31.0
+# ... rest
+```
+
+### 5. Update README.md
+```yaml
+---
+hardware: zero-a10g  # For ZeroGPU Pro
+sdk_version: 4.31.0
+---
+```
+
+## All Changes Applied ✅
+
+The following files have been updated:
+- ✅ `app.py` - Added `import spaces` at top, GPU decorators, lazy loading
+- ✅ `requirements.txt` - Added `spaces` package
+- ✅ `README.md` - Added hardware configuration
+
+## Deploy Now
+
+Simply push to your Hugging Face Space:
+
+```bash
+git add app.py requirements.txt README.md
+git commit -m "Fix ZeroGPU CUDA initialization error"
+git push
+```
+
+## Test Result
+
+Your Space should now:
+1. ✅ Start without CUDA errors
+2. ✅ Allocate GPU only when needed (clicks or processing)
+3. ✅ Work with ZeroGPU Pro subscription
+
