ComfyUI es una herramienta potente para la generación de imágenes con IA, que ofrece flexibilidad y control sobre los flujos de trabajo. En este artículo, te guiaremos por el proceso de instalación de ComfyUI en un equipo Windows, incluidos los requisitos del sistema, los pasos de instalación y consejos para solucionar problemas.
Tabla de contenido
Requisitos del sistema
Antes de comenzar el proceso de instalación, asegúrate de que tu sistema cumpla los siguientes requisitos previos de hardware y software:
Requisitos de hardware
- Procesador: CPU moderna de varios núcleos (se recomienda Intel i5/i7 o AMD Ryzen).
- GPU: GPU NVIDIA con compatibilidad con CUDA (mínimo 6GB VRAM, aunque 8GB+ VRAM es ideal para un mejor rendimiento). Por ejemplo:
- NVIDIA GTX 1660 o superior
- GPU NVIDIA RTX 3060/3070/3080/de las series 40 y 50
- GPU NVIDIA de las series A y Tesla
Requisitos de software
- Sistema operativo: Windows 10 o Windows 11 (64 bits).
- Versión de Python: Python 3.10 o posterior.
- Controladores NVIDIA: Asegúrate de que los controladores más recientes estén instalados para garantizar la compatibilidad con CUDA.
- Disponible en Descargas de controladores de NVIDIA.
- Instala NVIDIA CUDA:
- Git: Git debe estar instalado para clonar el repositorio.
- Disponible en Git for Windows.
Guía paso a paso para instalar ComfyUI en Windows

Que se puede descargar directamente haciendo clic en descargar.
Paso 4: Ejecuta ComfyUI
Paso 5: Prueba a usar el prompt y el modelo predeterminados para generar una imagen
Al hacer clic en ejecutar, aparece un error.
Error completo a continuación:
Informe de errores de ComfyUI
Detalles del error
- ID de nodo: 7
- Tipo de nodo: CLIPTextEncode
- Tipo de excepción: RuntimeError
- Mensaje de excepción: CUDA error: operation not supported
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1
Compile withTORCH_USE_CUDA_DSAto enable device-side assertions.

Después de investigar, descubrí que el problema ya se había mencionado en GitHub:
El ejecutable de ComfyUI de escritorio (Windows) no acepta parámetros en su línea de comandos · Issue #7087 · comfyanonymous/ComfyUI
Mitigación:
La mitigación consiste en establecer «Use CUDA malloc for memory allocation» en deshabilitado .
Paso 6: Genera la imagen
Después de resolver el problema y volver a hacer clic en ejecutar, por fin pude generar la imagen.
Verificación de la instalación
Para asegurarte de que ComfyUI está instalado correctamente y funciona:
- Prueba flujos de trabajo básicos generando imágenes de muestra.
- Comprueba el uso de la GPU con herramientas como Administrador de tareas o NVIDIA-SMI para confirmar que la aceleración de GPU está activa.
Solución de problemas comunes
Problema 1: Python no se reconoce
- Asegúrate de que Python se añada a tu PATH durante la instalación.
- Si no es así, añade manualmente el directorio de Python a tu PATH a través de Variables de entorno.
Problema 2: Errores de compatibilidad con CUDA
- Verifica que tus controladores NVIDIA y el kit de herramientas CUDA estén actualizados.
- Comprueba la compatibilidad de tu GPU con la versión de CUDA instalada.
Conclusión
Si sigues esta guía, ya deberías tener ComfyUI instalado y en funcionamiento en tu equipo Windows. Con su interfaz intuitiva y sus potentes funciones, estás listo para explorar flujos de trabajo de generación de imágenes con IA.
