-# Transfer Learning Base Configuration Feature
-
-## Overview
-This feature implements automatic loading of base configurations when "Train on COCO" transfer learning is selected. Base parameters are loaded from `backend/data/` based on the selected YOLOX model, and these protected fields are displayed as greyed out and non-editable in the frontend.
-
-## Components Modified/Created
-
-### Backend
-
-#### 1. Base Configuration Files (`backend/data/`)
-- **`yolox_s.py`** - Base config for YOLOX-Small (depth=0.33, width=0.50)
-- **`yolox_m.py`** - Base config for YOLOX-Medium (depth=0.67, width=0.75)
-- **`yolox_l.py`** - Base config for YOLOX-Large (depth=1.0, width=1.0)
-- **`yolox_x.py`** - Base config for YOLOX-XLarge (depth=1.33, width=1.25)
-
-Each file contains a `BaseExp` class with protected parameters:
-- Model architecture (depth, width, activation)
-- Training hyperparameters (max_epoch, warmup_epochs, scheduler, etc.)
-- Optimizer settings (momentum, weight_decay)
-- Augmentation probabilities (mosaic_prob, mixup_prob, etc.)
-- Input/output sizes
-
-#### 2. Services (`backend/services/generate_yolox_exp.py`)
-**New functions:**
-- `load_base_config(selected_model)` - Dynamically loads base config using importlib
-- Modified `generate_yolox_inference_exp()` to support `use_base_config` parameter
-- Base config merging logic: base → user overrides → defaults
-
-**Behavior:**
-- `transfer_learning='coco'` → loads base config + applies user overrides
-- `transfer_learning='sketch'` → uses only user-defined values
-- Protected parameters from base config are preserved unless explicitly overridden
-
-#### 3. API Routes (`backend/routes/api.py`)
-**New endpoint:**
-```python
-@api_bp.route('/base-config/<model_name>', methods=['GET'])
-def get_base_config(model_name):
-```
-Returns the base configuration JSON for a specific YOLOX model.
-
-### Frontend
-
-#### 1. HTML (`edit-training.html`)
-**Added:**
-- Info banner to indicate when base config is active
-- CSS styles for disabled input fields (grey background, not-allowed cursor)
-- Visual feedback showing which model's base config is loaded
-
-**Banner HTML:**
-```html
-<div id="base-config-info" style="display:none; ...">
-    🔒 Base Configuration Active
-    Protected parameters are loaded from [model] base config
-</div>
-```
-
-**CSS for disabled fields:**
-```css
-.setting-row input[type="number"]:disabled,
-.setting-row input[type="text"]:disabled,
-.setting-row input[type="checkbox"]:disabled {
-    background: #d3d3d3 !important;
-    color: #666 !important;
-    cursor: not-allowed !important;
-    border: 1px solid #999 !important;
-}
-```
-
-#### 2. JavaScript (`js/start-training.js`)
-**New functionality:**
-
-1. **Base Config Loading:**
-   ```javascript
-   function loadBaseConfig(modelName)
-   ```
-   Fetches base config from `/api/base-config/<model>`
-
-2. **Apply Base Config:**
-   ```javascript
-   function applyBaseConfig(config, isCocoMode)
-   ```
-   - Applies config values to form fields
-   - Disables and greys out protected fields
-   - Shows/hides info banner
-   - Adds tooltips to disabled fields
-
-3. **Update Transfer Learning Mode:**
-   ```javascript
-   function updateTransferLearningMode()
-   ```
-   - Monitors changes to "Transfer Learning" dropdown
-   - Monitors changes to "Select Model" dropdown
-   - Loads appropriate base config when COCO mode is selected
-   - Clears base config when sketch mode is selected
-
-4. **Form Submission Enhancement:**
-   - Temporarily enables disabled fields before submission
-   - Ensures protected parameters are included in form data
-   - Re-disables fields after collection
-
-**Protected Fields List:**
-```javascript
-const protectedFields = [
-    'depth', 'width', 'act', 'max_epoch', 'warmup_epochs', 'warmup_lr',
-    'scheduler', 'no_aug_epochs', 'min_lr_ratio', 'ema', 'weight_decay',
-    'momentum', 'input_size', 'mosaic_scale', 'test_size', 'enable_mixup',
-    'mosaic_prob', 'mixup_prob', 'hsv_prob', 'flip_prob', 'degrees',
-    'translate', 'shear', 'mixup_scale', 'print_interval', 'eval_interval'
-];
-```
-
-## User Flow
-
-### 1. Normal Custom Training (Train from sketch)
-- User selects model: e.g., "YOLOX-s"
-- User selects "Train from sketch"
-- All fields are editable (white background)
-- User can customize all parameters
-- Submission uses user-defined values only
-
-### 2. COCO Transfer Learning (Train on COCO)
-- User selects model: e.g., "YOLOX-s"
-- User selects "Train on coco"
-- **Automatic actions:**
-  1. Frontend calls `/api/base-config/YOLOX-s`
-  2. Base config is loaded and applied
-  3. Protected fields become greyed out and disabled
-  4. Green info banner appears: "🔒 Base Configuration Active"
-  5. Tooltip on hover: "Protected by base config for YOLOX-s. Switch to 'Train from sketch' to customize."
-- User can still edit non-protected fields
-- On submit: both base config values AND user overrides are sent to backend
-- Backend generates exp.py with merged settings
-
-### 3. Switching Models
-- User changes from "YOLOX-s" to "YOLOX-l" (while in COCO mode)
-- Frontend automatically:
-  1. Fetches new base config for YOLOX-l
-  2. Updates field values (depth=1.0, width=1.0, etc.)
-  3. Updates banner text to show "YOLOX-l"
-- Protected parameters update to match new model's architecture
-
-## Testing
-
-### Manual Test Steps:
-
-1. **Test Base Config Loading:**
-   ```bash
-   cd backend/data
-   python test_base_configs.py
-   ```
-   Should display all parameters for yolox-s, yolox-m, yolox-l, yolox-x
-
-2. **Test API Endpoint:**
-   ```bash
-   # Start Flask server
-   cd backend
-   python app.py
-   
-   # In another terminal:
-   curl http://localhost:3000/api/base-config/YOLOX-s
-   ```
-   Should return JSON with depth, width, activation, etc.
-
-3. **Test Frontend:**
-   - Open `edit-training.html?id=<project_id>` in browser
-   - Select "YOLOX-s" model
-   - Select "Train on coco" → fields should grey out
-   - Select "Train from sketch" → fields should become editable
-   - Switch to "YOLOX-l" (in COCO mode) → values should update
-   - Open browser console and check for: `Applied base config. Protected fields: depth, width, ...`
-
-4. **Test Form Submission:**
-   - With COCO mode active (fields greyed out)
-   - Click "Save Parameters"
-   - Check browser Network tab → POST to `/api/yolox-settings`
-   - Verify payload includes protected parameters (depth, width, etc.)
-   - Check Flask logs for successful save
-
-### Expected Behaviors:
-
-✅ **COCO mode + YOLOX-s:**
-- depth: 0.33 (greyed out)
-- width: 0.50 (greyed out)
-- activation: silu (greyed out)
-- Info banner visible
-
-✅ **COCO mode + YOLOX-l:**
-- depth: 1.0 (greyed out)
-- width: 1.0 (greyed out)
-- activation: silu (greyed out)
-
-✅ **Sketch mode:**
-- All fields white/editable
-- No info banner
-- User can set any values
-
-## Documentation
-
-- **`backend/data/README.md`** - Complete guide on base config system
-- **`backend/data/test_base_configs.py`** - Test script for base configs
-
-## Benefits
-
-1. **Proven defaults:** Users start with battle-tested COCO pretraining settings
-2. **Prevents mistakes:** Can't accidentally break model architecture by changing depth/width
-3. **Easy customization:** Can still override specific parameters if needed
-4. **Visual feedback:** Clear indication of which fields are protected
-5. **Model-specific:** Each model (s/m/l/x) has appropriate architecture defaults
-6. **Flexible:** Can easily add new models by creating new base config files
-
-## Future Enhancements
-
-- Add "Override" button next to protected fields to unlock individual parameters
-- Show diff comparison between base config and user overrides
-- Add validation warnings if user tries values far from base config ranges
-- Export final merged config as preview before training

-
-## 🚀 Getting Started
-
-1. **Install dependencies:**
-   ```bash
-   cd backend
-   python -m venv venv
-   .\venv\Scripts\Activate.ps1  # Windows
-   pip install -r requirements.txt
-   ```
-
-2. **Run the server:**
-   ```bash
-   python start.py
-   ```
-
-3. **Server runs at:** `http://0.0.0.0:3000`
-
-## 📦 Dependencies Installed
-
-- Flask 3.0.0 - Web framework
-- Flask-CORS 4.0.0 - Cross-origin resource sharing
-- Flask-SQLAlchemy 3.1.1 - ORM integration
-- SQLAlchemy 2.0.23 - Database ORM
-- PyMySQL 1.1.0 - MySQL driver
-- requests 2.31.0 - HTTP client
-- Pillow 10.1.0 - Image processing
-
-## ⚠️ Important Notes
-
-1. **Virtual Environment**: Always activate the virtual environment before running
-2. **Database**: MySQL must be running with the `myapp` database created
-3. **Credentials**: Update database credentials in `app.py` if needed
-4. **Python Version**: Requires Python 3.8 or higher
-
-## 🧪 Testing
-
-Test the conversion:
-```bash
-# Get all training projects
-curl http://localhost:3000/api/training-projects
-
-# Get Label Studio projects
-curl http://localhost:3000/api/label-studio-projects
-```
-
-## 📝 Original Files
-
-Your original Node.js files remain untouched:
-- server.js
-- package.json
-- routes/api.js
-- models/*.js (JavaScript)
-- services/*.js (JavaScript)
-
-You can keep them as backup or remove them once you verify the Python version works correctly.
-
-## 🔍 What to Verify
-
-1. ✅ Database connection works
-2. ✅ All API endpoints respond correctly
-3. ✅ File uploads work
-4. ✅ Label Studio integration works
-5. ✅ YOLOX training can be triggered
-6. ✅ COCO JSON generation works
-

-# Quick Start Guide - Python Backend
-
-## Step-by-Step Setup
-
-### 1. Install Python
-Make sure you have Python 3.8 or higher installed:
-```bash
-python --version
-```
-
-### 2. Create Virtual Environment
-```bash
-cd backend
-python -m venv venv
-```
-
-### 3. Activate Virtual Environment
-
-**Windows:**
-```powershell
-.\venv\Scripts\Activate.ps1
-```
-
-**Linux/Mac:**
-```bash
-source venv/bin/activate
-```
-
-### 4. Install Dependencies
-```bash
-pip install -r requirements.txt
-```
-
-### 5. Verify Database Connection
-Make sure MySQL is running and the database `myapp` exists:
-```sql
-CREATE DATABASE IF NOT EXISTS myapp;
-```
-
-### 6. Run the Server
-```bash
-python start.py
-```
-
-Or:
-```bash
-python app.py
-```
-
-The server should now be running at `http://0.0.0.0:3000`
-
-## Testing the API
-
-Test if the server is working:
-```bash
-curl http://localhost:3000/api/training-projects
-```
-
-## Common Issues
-
-### ModuleNotFoundError
-If you get import errors, make sure you've activated the virtual environment and installed all dependencies.
-
-### Database Connection Error
-Check that:
-- MySQL is running
-- Database credentials in `app.py` are correct
-- Database `myapp` exists
-
-### Port Already in Use
-If port 3000 is already in use, modify the port in `app.py`:
-```python
-app.run(host='0.0.0.0', port=3001, debug=True)
-```
-
-## What Changed from Node.js
-
-1. **Server Framework**: Express.js → Flask
-2. **ORM**: Sequelize → SQLAlchemy
-3. **HTTP Client**: node-fetch → requests
-4. **Package Manager**: npm → pip
-5. **Dependencies**: package.json → requirements.txt
-6. **Startup**: `node server.js` → `python app.py`
-
-## Next Steps
-
-1. Test all API endpoints
-2. Update frontend to point to the new Python backend (if needed)
-3. Migrate any remaining Node.js-specific logic
-4. Test file uploads and downloads
-5. Test YOLOX training functionality

+## 1. Einleitung
+
+### 1.1 Das Unternehmen
+
+[HIER INHALT VON KOLLEGE ÜBERNEHMEN - Firmenbeschreibung, Standort, Mitarbeiter, Branche, etc.]
+
+### 1.2 Projektumfeld
+
+[HIER INHALT VON KOLLEGE ÜBERNEHMEN - Übergeordnetes Projekt, Teamstruktur, Projektorganisation, etc.]
+
+### 1.3 Projektziel
+
+Der **mb ai Trainer** ist eine webbasierte Anwendung zur vollständigen Verwaltung und Durchführung von YOLOX-Modelltrainings im Bereich Computer Vision. Das System wurde entwickelt, um den gesamten Machine Learning Workflow - von der Datenannotation über das Training bis zur Modell-Evaluierung - in einer einheitlichen Plattform zu integrieren.
+
+**Hauptziele des Projekts:**
+
+- Entwicklung einer benutzerfreundlichen Weboberfläche zur Verwaltung von Trainingsprojekten
+- Integration von Label Studio für professionelle Bildannotation
+- Implementierung einer robusten Datenverwaltung mit MySQL
+- Automatisierung des YOLOX-Trainingsprozesses
+- Bereitstellung eines Transfer Learning Systems mit vordefinierten Basis-Konfigurationen
+- Zentrale Verwaltung aller Trainingsparameter und -verläufe
+
+### 1.4 Projektbegründung
+
+Im Bereich des Machine Learning für Computer Vision existieren zahlreiche isolierte Tools für verschiedene Aufgaben (Annotation, Training, Evaluierung). Dies führt zu:
+
+- **Hohem Verwaltungsaufwand:** Daten müssen zwischen verschiedenen Tools transferiert werden
+- **Fehlerpotential:** Manuelle Konfiguration von Trainingsskripten ist fehleranfällig
+- **Keine Nachvollziehbarkeit:** Trainingsverläufe und verwendete Parameter sind nicht zentral dokumentiert
+- **Steile Lernkurve:** Neue Teammitglieder müssen mehrere Tools erlernen
+
+Der mb ai Trainer löst diese Probleme durch eine integrierte Plattform, die alle notwendigen Funktionen vereint.

+
+### 3.2 Systemarchitektur
+
+#### 3.2.1 Backend-Architektur
+
+Das Backend des mb ai Trainer ist als modulare Python/Flask-Anwendung aufgebaut:
+
+```

+└── routes/
+    └── api.py              # REST API Endpoints
+```
+
+**Datenfluss:**
+
+1. **Projektanlage:** Frontend → POST `/api/training-projects` → MySQL
+2. **Label Studio Sync:** Backend → Label Studio API → MySQL (Images, Annotations)
+3. **Transfer Learning:**
+   - Frontend wählt "Train on coco" + Model
+   - GET `/api/base-config/<model_name>` → Basis-Config laden
+   - Frontend sperrt geschützte Felder
+4. **Training Start:**
+   - POST `/api/yolox-settings` → Settings speichern
+   - POST `/api/start-yolox-training` → Exp.py generieren
+   - YOLOX Training starten
+
+#### 3.2.2 Basis-Konfiguration Format
+
+```python
+class BaseExp:
+    """Base configuration for YOLOX-S with COCO pretrained weights"""
+    # Model architecture parameters (protected)
+    depth = 0.33
+    width = 0.50
+    
+    # Training parameters (protected)
+    scheduler = "yoloxwarmcos"
+    activation = "silu"
+    # ... weitere Parameter
+```
+
+#### 3.2.3 API Design
+
+**Endpoint:** `GET /api/base-config/<model_name>`
+
+**Response:**
+```json
+{
+  "depth": 0.33,
+  "width": 0.50,
+  "activation": "silu",
+  "scheduler": "yoloxwarmcos",
+  // ... weitere Parameter
+}
+```
+
+### 3.3 Implementierung
+
+#### 3.3.1 Backend: Dynamic Module Loading
+
+Die Basis-Konfigurationen werden zur Laufzeit dynamisch geladen:
+
+```python
+import importlib.util
+import os
+
+def load_base_config(selected_model):
+    """Dynamically load base configuration for selected model"""
+    model_map = {
+        'yolox-s': 'yolox_s.py',
+        'yolox-m': 'yolox_m.py',
+        'yolox-l': 'yolox_l.py',
+        'yolox-x': 'yolox_x.py'
+    }
+    
+    file_name = model_map.get(selected_model.lower())
+    if not file_name:
+        return None
+    
+    base_dir = os.path.join(os.path.dirname(__file__), '..', 'data')
+    file_path = os.path.join(base_dir, file_name)
+    
+    # Dynamic import
+    spec = importlib.util.spec_from_file_location("base_exp", file_path)
+    module = importlib.util.module_from_spec(spec)
+    spec.loader.exec_module(module)
+    
+    return module.BaseExp
+```
+
+**Vorteile:**
+- Keine hardcodierten Imports
+- Neue Modelle können ohne Code-Änderung hinzugefügt werden
+- Klare Trennung von Konfiguration und Logik
+
+#### 3.3.2 Backend: Configuration Merging
+
+Die Merge-Strategie kombiniert drei Quellen:
+
+```python
+def generate_yolox_inference_exp(training_id, options, use_base_config=True):
+    """Generate exp.py with base config support"""
+    
+    # 1. Load base configuration
+    base_config = load_base_config(selected_model) if use_base_config else None
+    
+    # 2. Load user-defined values from database
+    training = db.session.get(Training, training_id)
+    
+    # 3. Merge with priority: base > user > defaults
+    final_config = {}
+    
+    # Protected parameters from base config
+    protected_params = ['depth', 'width', 'activation', 'scheduler', ...]
+    
+    for param in protected_params:
+        if base_config and hasattr(base_config, param):
+            final_config[param] = getattr(base_config, param)
+        elif hasattr(training, param):
+            final_config[param] = getattr(training, param)
+        else:
+            final_config[param] = DEFAULT_VALUES.get(param)
+    
+    return final_config
+```
+
+**Priorität:**
+1. **Base Config** (höchste Priorität bei COCO-Mode)
+2. **User Values** (für nicht-geschützte Parameter)
+3. **Default Values** (Fallback)
+
+#### 3.3.3 Frontend: Field Locking
+
+Das Frontend zeigt geschützte Felder visuell an:
+
+```javascript
+const protectedFields = [
+    'depth', 'width', 'activation', 'scheduler', 'nmsthre', 
+    'momentum', 'weight_decay', 'warmup_epochs', 'max_epoch',
+    // ... weitere Felder
+];
+
+function applyBaseConfig(config, isCocoMode) {
+    protectedFields.forEach(field => {
+        const input = document.querySelector(`[name="${field}"]`);
+        
+        if (input && config.hasOwnProperty(field)) {
+            // Set value
+            input.value = config[field];
+            
+            if (isCocoMode) {
+                // Lock field
+                input.disabled = true;
+                input.style.backgroundColor = '#d3d3d3';
+                input.style.cursor = 'not-allowed';
+                input.title = 'This parameter is locked by base configuration';
+            }
+        }
+    });
+    
+    // Show/hide info banner
+    const banner = document.getElementById('base-config-info');
+    banner.style.display = isCocoMode ? 'block' : 'none';
+}
+```
+
+**UI-Features:**
+- Grauer Hintergrund für gesperrte Felder
+- Cursor: `not-allowed` für visuelle Rückmeldung
+- Tooltip erklärt warum Feld gesperrt ist
+- Grüner Info-Banner zeigt aktive Basis-Konfiguration
+
+#### 3.3.4 Frontend: Field Name Mapping
+
+Alias-Handling für Backend/Frontend Unterschiede:
+
+```javascript
+const fieldNameMap = {
+    'activation': 'act',        // Backend: activation, Frontend: act
+    'nms_thre': 'nmsthre'       // Backend: nms_thre, Frontend: nmsthre
+};
+
+function applyBaseConfig(config, isCocoMode) {
+    for (const [backendName, value] of Object.entries(config)) {
+        // Try direct match first
+        let input = document.querySelector(`[name="${backendName}"]`);
+        
+        // Try mapped name if direct match fails
+        if (!input && fieldNameMap[backendName]) {
+            const frontendName = fieldNameMap[backendName];
+            input = document.querySelector(`[name="${frontendName}"]`);
+        }
+        
+        if (input) {
+            input.value = value;
+            // ... weitere Logik
+        }
+    }
+}
+```
+
+### 3.4 Testing und Validierung
+
+#### 3.4.1 Unit Tests
+
+Erstellte Test-Suite für Basis-Konfigurationen:
+
+```python
+# backend/data/test_base_configs.py
+import importlib.util
+import os
+
+def test_base_config(file_name, expected_depth, expected_width):
+    """Test if base config loads correctly"""
+    file_path = os.path.join(os.path.dirname(__file__), file_name)
+    
+    spec = importlib.util.spec_from_file_location("base_exp", file_path)
+    module = importlib.util.module_from_spec(spec)
+    spec.loader.exec_module(module)
+    
+    config = module.BaseExp
+    assert config.depth == expected_depth
+    assert config.width == expected_width
+    # ... weitere Assertions
+
+# Run tests
+test_base_config('yolox_s.py', 0.33, 0.50)

+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:
