# Lazy Loading Implementation for ANNOTATE App
|
||||
|
||||
## Overview
|
||||
|
||||
Implemented lazy loading of NN models in the ANNOTATE app to improve startup time and reduce memory usage. Models are now loaded on-demand when the user clicks a LOAD button.
|
||||
|
||||
---
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Backend Changes (`ANNOTATE/web/app.py`)
|
||||
|
||||
#### Removed Auto-Loading
|
||||
- Removed `_start_async_model_loading()` method
|
||||
- Models no longer load automatically on startup
|
||||
- Faster app initialization
|
||||
|
||||
#### Added Lazy Loading
|
||||
- New `_load_model_lazy(model_name)` method
|
||||
- Loads specific model on demand
|
||||
- Initializes orchestrator only when first model is loaded
|
||||
- Tracks loaded models in `self.loaded_models` dict
|
||||
|
||||
#### Updated Model State Tracking
|
||||
```python
|
||||
self.available_models = ['DQN', 'CNN', 'Transformer'] # Can be loaded
|
||||
self.loaded_models = {} # Currently loaded: {name: instance}
|
||||
```
|
||||
|
||||
#### New API Endpoint
|
||||
**`POST /api/load-model`**
|
||||
- Loads a specific model on demand
|
||||
- Returns success status and loaded models list
|
||||
- Parameters: `{model_name: 'DQN'|'CNN'|'Transformer'}`
|
||||
|
||||
#### Updated API Endpoint
|
||||
**`GET /api/available-models`**
|
||||
- Returns model state dict with load status
|
||||
- Response format:
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"models": [
|
||||
{"name": "DQN", "loaded": false, "can_train": false, "can_infer": false},
|
||||
{"name": "CNN", "loaded": true, "can_train": true, "can_infer": true},
|
||||
{"name": "Transformer", "loaded": false, "can_train": false, "can_infer": false}
|
||||
],
|
||||
"loaded_count": 1,
|
||||
"available_count": 3
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Frontend Changes (`ANNOTATE/web/templates/components/training_panel.html`)
|
||||
|
||||
#### Updated Model Selection
|
||||
- Shows load status in dropdown: "DQN (not loaded)" vs "CNN ✓"
|
||||
- Tracks model states from API
|
||||
|
||||
#### Dynamic Button Display
|
||||
- **LOAD button**: Shown when model selected but not loaded
|
||||
- **Train button**: Shown when model is loaded
|
||||
- **Inference button**: Enabled only when model is loaded
|
||||
|
||||
#### Button State Logic
|
||||
```javascript
|
||||
function updateButtonState() {
|
||||
if (!selectedModel) {
|
||||
// No model selected - hide all action buttons
|
||||
} else if (modelState.loaded) {
|
||||
// Model loaded - show train/inference buttons
|
||||
} else {
|
||||
// Model not loaded - show LOAD button
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Load Button Handler
|
||||
- Disables button during loading
|
||||
- Shows spinner: "Loading..."
|
||||
- Refreshes model list on success
|
||||
- Re-enables button on error
|
||||
|
||||

|
||||
|
||||
## User Experience
|
||||
|
||||
### Before
|
||||
1. App starts
|
||||
2. All models load automatically (slow, ~10-30 seconds)
|
||||
3. User waits for loading to complete
|
||||
4. Models ready for use
|
||||
|
||||
### After
|
||||
1. App starts immediately (fast, <1 second)
|
||||
2. User sees model dropdown with "(not loaded)" status
|
||||
3. User selects model
|
||||
4. User clicks "LOAD" button
|
||||
5. Model loads in background (~5-10 seconds)
|
||||
6. "Train Model" and "Start Live Inference" buttons appear
|
||||
7. Model ready for use
|
||||
|
||||

|
||||
|
||||
## Benefits
|
||||
|
||||
### Performance
|
||||
- **Faster Startup**: App loads in <1 second vs 10-30 seconds
|
||||
- **Lower Memory**: Only loaded models consume memory
|
||||
- **On-Demand**: Load only the models you need
|
||||
|
||||
### User Experience
|
||||
- **Immediate UI**: No waiting for app to start
|
||||
- **Clear Status**: See which models are loaded
|
||||
- **Explicit Control**: User decides when to load models
|
||||
- **Better Feedback**: Loading progress shown per model
|
||||
|
||||
### Development
|
||||
- **Easier Testing**: Test without loading all models
|
||||
- **Faster Iteration**: Restart app quickly during development
|
||||
- **Selective Loading**: Load only the model being tested
|
||||
|
||||

|
||||
|
||||
## API Usage Examples
|
||||
|
||||
### Check Model Status
|
||||
```javascript
|
||||
fetch('/api/available-models')
|
||||
.then(r => r.json())
|
||||
.then(data => {
|
||||
console.log('Available:', data.available_count);
|
||||
console.log('Loaded:', data.loaded_count);
|
||||
data.models.forEach(m => {
|
||||
console.log(`${m.name}: ${m.loaded ? 'loaded' : 'not loaded'}`);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Load a Model
|
||||
```javascript
|
||||
fetch('/api/load-model', {
|
||||
method: 'POST',
|
||||
headers: {'Content-Type': 'application/json'},
|
||||
body: JSON.stringify({model_name: 'DQN'})
|
||||
})
|
||||
.then(r => r.json())
|
||||
.then(data => {
|
||||
if (data.success) {
|
||||
console.log('Model loaded:', data.loaded_models);
|
||||
} else {
|
||||
console.error('Load failed:', data.error);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Model Loading Flow
|
||||
|
||||
1. **User selects model from dropdown**
|
||||
- `updateButtonState()` called
|
||||
- Checks if model is loaded
|
||||
- Shows appropriate button (LOAD or Train)
|
||||
|
||||
2. **User clicks LOAD button**
|
||||
- Button disabled, shows spinner
|
||||
- POST to `/api/load-model`
|
||||
- Backend calls `_load_model_lazy(model_name)`
|
||||
|
||||
3. **Backend loads model**
|
||||
- Initializes orchestrator if needed
|
||||
- Calls model-specific init method:
|
||||
- `_initialize_rl_agent()` for DQN
|
||||
- `_initialize_cnn_model()` for CNN
|
||||
- `_initialize_transformer_model()` for Transformer
|
||||
- Stores in `self.loaded_models`
|
||||
|
||||
4. **Frontend updates**
|
||||
- Refreshes model list
|
||||
- Updates dropdown (adds ✓)
|
||||
- Shows Train/Inference buttons
|
||||
- Hides LOAD button
|
||||
|
||||
### Error Handling
|
||||
|
||||
- **Network errors**: Button re-enabled, error shown
|
||||
- **Model init errors**: Logged, error returned to frontend
|
||||
- **Missing orchestrator**: Creates on first load
|
||||
- **Already loaded**: Returns success immediately
|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
### Manual Testing Steps
|
||||
|
||||
1. **Start app**
|
||||
```bash
|
||||
cd ANNOTATE
|
||||
python web/app.py
|
||||
```
|
||||
|
||||
2. **Check initial state**
|
||||
- Open browser to http://localhost:5000
|
||||
- Verify app loads quickly (<1 second)
|
||||
- Check model dropdown shows "(not loaded)"
|
||||
|
||||
3. **Load a model**
|
||||
- Select "DQN" from dropdown
|
||||
- Verify "Load Model" button appears
|
||||
- Click "Load Model"
|
||||
- Verify spinner shows
|
||||
- Wait for success message
|
||||
- Verify "Train Model" button appears
|
||||
|
||||
4. **Train with loaded model**
|
||||
- Create some annotations
|
||||
- Click "Train Model"
|
||||
- Verify training starts
|
||||
|
||||
5. **Load another model**
|
||||
- Select "CNN" from dropdown
|
||||
- Verify "Load Model" button appears
|
||||
- Load and test
|
||||
|
||||
### API Testing
|
||||
|
||||
```bash
|
||||
# Check model status
|
||||
curl http://localhost:5000/api/available-models
|
||||
|
||||
# Load DQN model
|
||||
curl -X POST http://localhost:5000/api/load-model \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"model_name": "DQN"}'
|
||||
|
||||
# Check status again (should show DQN loaded)
|
||||
curl http://localhost:5000/api/available-models
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Possible Improvements
|
||||
|
||||
1. **Unload Models**: Add button to unload models and free memory
|
||||
2. **Load All**: Add button to load all models at once
|
||||
3. **Auto-Load**: Remember last used model and auto-load on startup
|
||||
4. **Progress Bar**: Show detailed loading progress
|
||||
5. **Model Info**: Show model size, memory usage, last trained date
|
||||
6. **Lazy Orchestrator**: Don't create orchestrator until first model loads
|
||||
7. **Background Loading**: Load models in background without blocking UI
|
||||
|
||||
### Code Locations
|
||||
|
||||
- **Backend**: `ANNOTATE/web/app.py`
|
||||
- `_load_model_lazy()` method
|
||||
- `/api/available-models` endpoint
|
||||
- `/api/load-model` endpoint
|
||||
|
||||
- **Frontend**: `ANNOTATE/web/templates/components/training_panel.html`
|
||||
- `loadAvailableModels()` function
|
||||
- `updateButtonState()` function
|
||||
- Load button handler
