# Fixing Memory Issue - Windows Virtual Memory

## Problem
```
OSError: The paging file is too small for this operation to complete. (os error 1455)
```

Your system needs more virtual memory to load the large AI models (1.21GB+).

## Solution: Increase Windows Virtual Memory

### Step-by-Step Instructions:

1. **Open System Properties**
   - Press `Windows Key + Pause/Break` OR
   - Right-click "This PC" → Properties → Advanced system settings

2. **Access Virtual Memory Settings**
   - Click "Advanced" tab
   - Under "Performance", click "Settings..."
   - Click "Advanced" tab again
   - Under "Virtual memory", click "Change..."

3. **Configure Virtual Memory**
   - **Uncheck** "Automatically manage paging file size for all drives"
   - Select your C: drive (or main drive)
   - Select "Custom size"
   - Set values:
     - **Initial size (MB):** 8192 (8 GB)
     - **Maximum size (MB):** 16384 (16 GB)
   - Click "Set"
   - Click "OK" on all dialogs

4. **Restart Your Computer**
   - This is required for changes to take effect

5. **Try Running the App Again**
   ```powershell
   python app.py
   ```

## Alternative: Quick Fix (Temporary)

If you can't change virtual memory settings, try these:

### Option A: Close Other Programs
- Close all browsers, apps, and programs
- This frees up RAM
- Then try running the app again

### Option B: Use Smaller Model (Code Change)
Edit `classifier/config.py` to use a smaller model if available.

### Option C: Run with Priority
```powershell
# Run Python with higher priority
Start-Process python -ArgumentList "app.py" -WindowStyle Normal -Wait
```

## Checking Current Virtual Memory

To see your current settings:
1. Follow steps 1-2 above
2. Note the current "Total paging file size" at the bottom

Typical recommendations:
- **Minimum:** 1.5x your RAM
- **Recommended:** 2-3x your RAM
- **For ML models:** At least 8-16 GB

## After Fixing

Once virtual memory is increased and computer is restarted:
```powershell
cd "C:\Users\Tarak Jha\OneDrive - Coast to Coast Logistics\Desktop\HEALTHBOT\health-query-classifier"
python app.py
```

The models should load successfully!
