# Model Improvement Apps - Troubleshooting and Fix Summary

## Overview
This document summarizes the troubleshooting and fixes applied to the two model improvement apps in the aimodelshare library.

## Apps Fixed
1. **model_building_game.py** - Advanced model building game for experienced learners
2. **model_building_game_beginner.py** - Simplified beginner-friendly model building game

## Issues Identified

### Issue 1: Apps Not Exported
The two model building game apps were not exported in `aimodelshare/moral_compass/apps/__init__.py`, making them inaccessible to users.

### Issue 2: Gradio API Compatibility
Both apps had compatibility issues with Gradio 5.x:
- **model_building_game_beginner.py**: Used deprecated `gr.Box()` component (removed in Gradio 4.x)
- **model_building_game.py**: Incorrectly used `gr.TabbedInterface()` as a context manager

### Issue 3: Test References to Non-existent App
Tests referenced a non-existent `ai_lead_engineer` app instead of the actual model building game apps.

## Fixes Applied

### Fix 1: Export Model Building Game Apps
**File**: `aimodelshare/moral_compass/apps/__init__.py`

Added exports for both model building game apps:
```python
from .model_building_game import create_model_building_game_app, launch_model_building_game_app
from .model_building_game_beginner import create_model_building_game_beginner_app, launch_model_building_game_beginner_app
```

### Fix 2: Gradio 5 API Compatibility

#### model_building_game_beginner.py
Replaced deprecated `gr.Box()` with `gr.Group()` in 5 locations:
- Line 458: Model selection box
- Line 471: Complexity adjustment box
- Line 479: Data size selection box
- Line 486: Optional feature box

**Before:**
```python
with gr.Box():
    gr.Markdown("### 3️⃣ Data Size")
```

**After:**
```python
with gr.Group():
    gr.Markdown("### 3️⃣ Data Size")
```

#### model_building_game.py
Replaced incorrect `TabbedInterface` usage with `gr.Tabs()`:

**Before:**
```python
with gr.TabbedInterface(["Team Standings", "Individual Standings"], elem_id="lb-tabs") as lb_tabs:
    with gr.TabItem("Team Standings"):
        # content
    with gr.TabItem("Individual Standings"):
        # content
```

**After:**
```python
with gr.Tabs():
    with gr.TabItem("Team Standings"):
        # content
    with gr.TabItem("Individual Standings"):
        # content
```

### Fix 3: Update Tests
**File**: `tests/test_moral_compass_apps.py`

1. Updated `test_all_apps_exported_from_init()` to check for model building game apps instead of ai_lead_engineer
2. Updated `test_apps_with_custom_theme()` to test model building game apps with custom themes
3. Added two new dedicated tests:
   - `test_model_building_game_app_can_be_created()`
   - `test_model_building_game_beginner_app_can_be_created()`

## Verification

### Test Results
All 10 tests pass successfully:
```
✅ test_tutorial_app_can_be_created
✅ test_judge_app_can_be_created
✅ test_ai_consequences_app_can_be_created
✅ test_what_is_ai_app_can_be_created
✅ test_all_apps_exported_from_init
✅ test_judge_app_defendant_profiles
✅ test_what_is_ai_predictor
✅ test_apps_with_custom_theme
✅ test_model_building_game_app_can_be_created (NEW)
✅ test_model_building_game_beginner_app_can_be_created (NEW)
```

### Manual Verification
Both apps can be successfully imported and instantiated:
```python
from aimodelshare.moral_compass.apps import (
    create_model_building_game_app,
    create_model_building_game_beginner_app
)

app1 = create_model_building_game_app()  # ✓ Works
app2 = create_model_building_game_beginner_app()  # ✓ Works
```

### Security Scan
CodeQL analysis completed with **0 security vulnerabilities** found.

## Impact
- ✅ Both model improvement apps now load correctly
- ✅ Apps are properly exported and accessible to users
- ✅ Fully compatible with Gradio 5.x
- ✅ Comprehensive test coverage
- ✅ No security vulnerabilities introduced

## Usage Example
```python
# Import the model building game apps
from aimodelshare.moral_compass.apps import (
    create_model_building_game_app,
    launch_model_building_game_app,
    create_model_building_game_beginner_app,
    launch_model_building_game_beginner_app
)

# Create and launch the advanced version
app = create_model_building_game_app(theme_primary_hue="indigo")
app.launch(share=False, height=1200)

# Or use the convenience launcher
launch_model_building_game_app(height=1200, share=False)

# For beginners, use the simplified version
launch_model_building_game_beginner_app(height=1100, share=False)
```

## Files Modified
1. `aimodelshare/moral_compass/apps/__init__.py` - Added exports
2. `aimodelshare/moral_compass/apps/model_building_game.py` - Fixed Gradio API usage
3. `aimodelshare/moral_compass/apps/model_building_game_beginner.py` - Fixed Gradio API usage
4. `tests/test_moral_compass_apps.py` - Updated and added tests

## Dependencies
The model building game apps require:
- `gradio>=4.0.0` (tested with 5.49.1)
- `networkx` (for playground functionality)
- `scikit-learn` (for model training)
- `pandas`, `numpy` (for data handling)

## Next Steps
The model improvement apps are now fully functional and ready for use in educational notebooks and interactive learning environments.
