## 🔧 Configuración de Token HuggingFace
|
751 |
-
|
752 |
-
Para usar Google Derm Foundation, configura tu token:
|
753 |
-
|
754 |
-
```bash
|
755 |
-
export HUGGINGFACE_TOKEN="tu_token_aqui"
|
756 |
-
```
|
757 |
-
|
758 |
-
O en Python:
|
759 |
-
```python
|
760 |
-
import os
|
761 |
-
os.environ['HUGGINGFACE_TOKEN'] = 'tu_token_aqui'
|
762 |
-
```

### Añadir Nuevos Modelos
|
785 |
-
|
786 |
-
Para añadir un nuevo modelo al sistema:
|
787 |
-
|
788 |
-
```python
|
789 |
-
MODEL_CONFIGS.append({
|
790 |
-
'name': 'Nombre del Modelo',
|
791 |
-
'id': 'huggingface/model-id',

### Tipos de Modelos Soportados
|
799 |
-
|
800 |
-
- **vit**: Vision Transformer
|
801 |
-
- **swin**: Swin Transformer
|
802 |
-
- **efficientnet**: EfficientNet
|
803 |
-
- **foundation**: Modelos foundation (como Google Derm)
|
804 |
-
|
805 |
-
### Pesos del Ensemble
|
806 |
-
|
807 |
-
Los pesos se asignan automáticamente según:
|
808 |
-
- Tipo de modelo (foundation > swin > efficientnet > vit)
|
809 |
-
- Confianza de la predicción
|
810 |
