You saved me from wasting thousands of times trying to solve this issue .. I was depressed and disappointed .. thanks to you its installed ♥

Thank you very much for explaining the installation, I didn't understand where the errors were coming from. Have a nice day

[@CaoCao2025]

Glad it helped

[@johnc9926]

Thank you so much! this worked for me for my Windows 11, 64x 32 system. I have a 16 gb ram, intel cpu. AMD. I just followed first half of video without the CUDA part cause i don't have it. Face swap runs well!

[@CaoCao2025]

thanks for your information

[@dreamstate5047]

This really was a great video and well explained, thank you for great work, this really solved my problem, and I was struggling for long, I bumped on your video after countless attempts at getting the reactor worked after a fresh OS install, But this worked for me finally. Awesome Video.

I have been trying for days with no success and then saw a post on the official channel for Reactor that someone else said to downgrade the onnxruntime. So after following your instructions here I Then downgraded CUDA to 11.8 and the added all the extras like you di in bin, lib and include to the 11.8 CUDA folder. resorting back to Cuda 11.8 then I removed the onnxruntime and then reinstanlled it downgradin it to 1.17.1 and Voila Success. python_embeded\python.exe -m pip uninstall -y onnxruntime onnxruntime-gpu python_embeded\python.exe -m pip install onnxruntime==1.17.1 FINALLLLLLYYYYYYYYYY!!!!!!!!

[@matteo.grossi]

What was't working for you? It installs everything without errors for me, it just won't load in ComfyUI.

[@CaoCao2025]

Congratulations

[@maxdeniel]

Hi friend, how you downgrade CUDA to 11.8? I still having the same problem, the same ERROR pops up: "CUDA_PATH is set but CUDA wasn't able to be loaded. Please install the correct version of CUDA and cuDNN as mentioned in the GPU requirements page......... etc etc etc"

[@legenDaCerita]

finally after 3 days of darkness with your help it can be solved. python_embeded\python.exe -m pip uninstall -y onnxruntime onnxruntime-gpu python_embeded\python.exe -m pip install onnxruntime==1.17.1 using this method and it work again like before thanks bro

[@djwhispers3157]

how do you force to uninstall onx?

[@IzzyDiamonds69]

Hi, thanks for the tutorial. Only one problem I have with REAKTOR, the fact that it ruins the color of the hair (it loses color due to contouring over the face) when applying the new face. Is there any solution to this situation? Thanks in advance.

[@CaoCao2025]

1. you could repair it using inpainting 2. try using roop instead of reactor

[@BeatCreationsGaming]

Great my friend. good share

[@Rohit_KushwahaBSP]

Looks Pretty

[@maxdeniel]

First of all thank yo very much for your videos, they are straight to the point. Great job my friend. Still having the same problem, the same ERROR pops up: "CUDA_PATH is set but CUDA wasn't able to be loaded. Please install the correct version of CUDA and cuDNN as mentioned in the GPU requirements page......... etc etc etc" I notice something different on my Installation process, I followed your instruction BUT at 1:15 (when Install.bat is executed), when you said "As you can see, we finish installing Onyx 1.16........" in my case, it does not install anything, it just shows the windows prompt like this: Installing. . . CUDA 12.1 OK Done Press any key to continue . . . The user @HiProfileAI said something about downgrade the CUDA version to 11.8, gonna try that as well.

[@CaoCao2025]

you might try uninstall the onnyx and install it again, follow the command line on video description

Hello, I have workflows that are shared on sites and are open to everyone. I download and install the missing models, lora, etc. in those workflows, but I still get errors. I want these to be fixed and prepared in a way that I can run. If I pay you, can you do these for me?

[@CaoCao2025]

Sorry, could you specify the error? Some Custom Node require you to install other thing. For example, reactor require to install Cuda. Some require a certain python version. I think you should check each custom node that it has, and see it github page, to make sure you don't need any new version. Also if you get the workflow from site, check the review and user reputation. Some time people upload workflow that simply don't work. Also by checking the review and comment you might find a clue about what to do with your error.

[@Tazastical]

good work1 :)

hi, i keep getting (IMPORT FAILED) ReActor Node for ComfyUI. there is a "fix" button there i select it but nothing chages. stuck in this error badly. i also install it manually but nothing changed. i don't know what is the problem.

do you already uninstall onnyx and install it again?

Unfortunately this is not working for me. I have tried other similar guides but it won't load ReActor. Even the "try fix" operation suggested by ComfyUI does not work. I don't even see any error message when installing the requirements. I am on windows 10. What am i missing?

you need to install CUDA Toolkit manually too, it's also a different from cuddn. I can't guide you with installing CUDA because i am afraid to mess up my setting. You can follow many other tutorial of installing Cuda Toolkit.

[@bohguss]

could you do this with multiple images as source? to get a more accurate face?

[@bohguss]

im guessing use a batch instead of load image? i'll try and come back

i think you could use a face model for reactor

batch will not work
