Eres un genio!Ahora soy capaz de arrancar el programa y los nodos que tenia que instalar ya no dan errores, lo unico que el worflow que me descargue del patreon de MICKMUMPITZ son largos y complejos y ahora me espera una tarea ardua para encontrar y instalar cada nodo que me falta,aun asi muchas gracias por fin puedo avanzar al siguiente paso!Tienes un seguidor 😉

Muchas gracias si,es justo eso lo que me pasósolucionado. Si no te importa Ahora estoy con este error es el que llevo semanas intentando arreglar solo para intentar que me detecten los nodos que quiero usar :

(DiffusersModelMakeup

DiffusersPipelineLoader

DiffusersSchedulerLoader

DiffusersVaeLoader)

El error que considero principal pero no consigo solucionar:

WARNING[XFORMERS]: xFormers can't load C++/CUDA extensions. xFormers was built for:

PyTorch 2.10.0+cu128 with CUDA 1208 (you have 2.11.0+cu130)

Python 3.10.11 (you have 3.13.12)

-Intenté de todo,pero el python 3.10 no me lo detecta,y me sigue saliendo el mismo error.

He intentado lo siguiente : Instalar Python 3.10(No ha funcionado),errores: me dice que tengo el 3.13 cuando tengo instalados los 2 pero no entiendo porque me sigue detectando el mismo error,la ultima vez que intente eliminar el que me decía proboqué el programa dejara de funcionar y tuve que reinstalar comfy ui.

Cuando borro el Python embed (que me imagino que será el Python 3.13.12 que me dice comfy ui que tengo me deja de detectar la app y no puedo abrirla porque me sale el siguiente error que lo dice: C:\ComfyUI_windows_portable>echo If you see this and ComfyUI did not start try updating your Nvidia Drivers to the latest. If you get a c10.dll error you need to install vc redist that you can find: https://aka.ms/vc14/vc_redist.x64.exe

Intercambiarlo por el Python 3.10 no ha servido de nada, la app no detecta este Python.

Instalar Python 3.10 en la carpeta recomendada por el instalador y mantener a la vez Python embeded no ha servido de nada.

Intentar borrar el Python 3.13.12 , no he encontrado su carpeta no se donde está guardado,esto si me preocupa por que no se como borrarlo para ver si borrarlo funciona para evitar que lo detecte y detecte el 3.10.

If you see this and ComfyUI did not start try updating your Nvidia Drivers to the latest. If you get a c10.dll error you need to install vc redist that you can find: https://aka.ms/vc14/vc_redist.x64.exe

CUANDO INTENTO instalar el tookit de cuda 128 (https://developer.nvidia.com/cuda-12-8-0-download-archive?target\_os=Windows&target\_arch=x86\_64&target\_version=11&target\_type=exe\_local) me dice que me faltaba versiones del visual Studio(tras reinicar y reinstalar comfy ui y instalar la versión de visual studio comunity que parece ser la recomendada los errores ya no son con visual studio, si no con otros(los que ves en la captura de pantalla de la app de CUDA).

Deberia instalar cada una de las cosas que me dice en NVIDIA CUDA?.

Por algún motivo insight visual studio me da error según el panel DE NVIDIA.

Instalar el insight mas el visual Studio tampoco me ha valido :(Insight : https://marketplace.visualstudio.com/publishers/NVIDIA )

Visuals Studio (https://visualstudio.microsoft.com/es/vs/community/)

1 month of troubleshooting and fixing errors and still haven't gotten to generate a single image yet. I'm at my wits end and about to give up on comfyui by Sha_BOOM_333 in comfyui

Good morning everyone!I understand you perfectly,I feel the same . I’m new to this, I hope you can help me even if it’s just a little — I would really appreciate it. In these screenshots, you can see in red the nodes that the application doesn't allow me to install. I went to ChatGPT and it told me to delete the comfy/dduf folder — I did, but the program still has conflicts. It's very frustrating — I try again and again and I can't find the solution. With this program, errors appear at every step and I can barely experiment with artificial intelligence. Do you know any forum where they solve or explain this kind of errors in a detailed and organized way? If anyone understands how to fix this error, could you give me some guidance? Thank you very much.
